Brian Cox refutes claims of climate change denier on Q&A

alcom says...

We will all enjoyed the freedom and comfort of fossil fuel since the industrial revolution. At some point, we all have to pay for the gigatons of mess that we're pumping in the air.

The smart money is on clean energy as oil bounces back above $40 per barrel after the global supply glut had it below $30. Coal investment has tanked since oil peaked in 2009 and solar plants and wind plants are often more cost effective over their lifetimes.

Farm of the Future Uses No Soil and 95% Less Water

MilkmanDan says...

I think corn would be doable, but the advantages would be less efficient compared to short plants.

At some level of efficiency, there is a break even point (which can also take into consideration shipping costs and fossil fuel usage to major metro areas). I'm pretty convinced that vertical farming could be a significantly good / efficient idea for those plants that it is best suited for, but I do think there would be some early-adoption issues that would make it less practical for tall stuff like corn. At least until it has been done enough to work out the kinks and economy of scale kicks in.

So at least for the time being, I think we'll see it first be applied to leafy plants and tuber / root plants. But I could definitely be a biased opinion since my family revolves around conventional corn farming on irrigated fields...

Chairman_woo said:

Think about it this way. Stack the corn trays just once and you just doubled your output for a given area.

You're right about getting less mileage from taller crops. But every vertical layer would in theory still double the area you have to work with each time you added one.

Scale this up to a skyscraper sized building and you could supply any city with all the food it could need locally.

It probably could start to skew the market towards squatter plants as you say, but I can't see why most if not all of the things we grow now couldn't be viable. (doubly so if they ever nail the process of growing meat)

Monsanto, America's Monster

newtboy says...

In first world countries....yes, or close to that much. Agreed. Not world wide.

Mechanized harvest is accepted in "natural" old school farming. Agreed, it would fall under the "industrial farming" methods, but is one of the least damaging.
>1000 acre farms do not count as "family farms" in my eyes, even if they are owned by a single family. So is Walmart, but it's not a mom and pop or family store.

Again, mechanization is not the same as industrialization, but does still do damage by over plowing, etc. I'm talking about monoculture crops, over application of man made fertilizers, herbicides, and pesticides. Grain was farmed "by hand" since farming existed with few problems, but more work involved. The work it takes to rehab a river system because industrial farming runoff contaminated and killed it is FAR more work than the extra work involved in farming using old school methods (which does not mean everything is done with hands, tools and machines have been in use for eons).

Roundup doesn't "break down" completely, and doesn't break down at all if it's washed into river systems and out of the UV light.

Once again, machines aren't all of "industrial farming", they are one of the least damaging facets, and they are not unknown in old school, smaller farming techniques. BUT....overuse of heavy equipment either over packs the soil, making it produce far less, or over plows the soil, making it run off and blow away (see the dust bowl). If it was ONLY about machinery, and ONLY industrial farming used machines, you would have a point, but neither is true.

No, actually overproducing on a piece of land like that makes it unusable quickly and new farm land is needed to replace it while it recuperates (if it ever can). Chemical fertilizers add salts that kill beneficial bacteria, "killing" the soil, sometimes permanently. producing double or triple the amount of food on the same land is beneficial in the extreme short term, and disastrous in the barely long term. (See 'dust bowl')

Man power is far less damaging to the environment than fossil fuels for the same amount of energy. Also, the people would use no more resources because they're in the field than they would anywhere else, so there's NO net gain to the energy used or demand on the environment if they farm instead of sit at a desk, but machines don't use energy when idle, so there is a net loss to the energy required if you replace them with pre-existing people.

Yes, you quoted it directly, buy your characterization of what that meant was insane. You claim they said Monsanto worked on the project (and other things) because they're evil and want to do evil and harm. The video actually said they do these things without much care for the negative consequences to others, and that makes them evil. I hope you can comprehend the distinct difference in those statements, and that your portrayal of what they said is not honest.

These Lizards Have Been Playing Rock-Paper-Scissors for 15MY

I question their claim of 15 million years.
I highly doubt they have fossils going back even 100,000 years that would allow them to figure out the color of those males.

If Meat Eaters Acted Like Vegans

transmorpher says...

Ok I'll try to divide up my wall text a bit better this time

I totally acknowledge that people in the past, and even in present day, some people have to live a certain way in order to survive, but for the vast majority of people that doesn't apply.


Taste:
Like most of the senses in the human body, the sense of taste is in a constant state re-calibration. It's highly subjective and easily influenced over mere seconds but also long periods of time. They say it takes 3 weeks to acclimatize from things you crave, from salt to heroin. That's why most healthy eating books tell you go to cold tofurkey (see what I did there ) for 3 weeks. It's all about the brain chemistry. After 3 straight weeks you aren't craving it. (The habit might still be there but, the chemically driven cravings are gone).
Try it yourself by eating an apple before and after some soft drink. First the apple will taste sweet, and after it will taste sour. Or try decreasing salt over a 3 week period, it'll taste bland at first, but if you go back after 3 weeks it'll be way too salty.



Food science:
One of the major things stopping me from not being vegan, was the health concerns, so I read a number of books about plant-based eating.
There is a new book "How Not To Die" by Dr. Michael Greger. If you want scientific proof of a plant based diet this the one stop shop. 500 pages explaining tens of thousands of studies, some going for decades and involving hundreds of thousands of people. I was blown away at the simple fact that so many studies get done. Most of them are interventional studies also, meaning they are able to show cause and effect (unlike observational or corrolational studies, as he explains in the book). 150 pages of this book alone are lists of references to studies. It's pure unbiased science. (It's not a vegan book either in case you are worried about him being biased).

At the risk of spoiling the book - whole foods like apples and broccoli doesn't give you cancer, in fact they go a long way to preventing it, some bean based foods are as effective as chemotherapy, and without the side effects. I thought it sounded it ridiculous, but the science is valid.
Of course you can visit his website he explains all new research almost daily at nutritionfacts.org in 1 or 2 minute videos.
He also has a checklist phone app called Dr.Greger's Daily Dozen.

There are other authors too, most of these ones have recipes too, such as Dr. John McDougall, Dr. Neal Barnard, Dr. Cadwell Esselstyn, Dr. Dean Ornish, Dr Joel Furhman.
Health-wise it's the best thing you can do for yourself. And if like me you thought eating healthy meant salads, you'd be as wrong as I was I haven't had a salad for years. My blood results and vitamin levels are exactly what the books said they would be.

Try it for 3 weeks, but make sure you do it the right way as explained in the books, and you'll be shouting from roof tops about what a change it's made to your life. The other thing is, you get to eat more, and the more you eat it's healthier. What a weird concept in a world where we are constantly being told to calorie count (it doesn't work btw).

Environmental:
I've read a lot about ethics, reason and evidence based thinking, as well as nutrition and health (as a result of my own skepticism). So I could and I enjoy talking about these all day long. On the environmental side of things, I'm not as aware, but there some documentaries such as Earthlings and Cowspiracy which paint a pretty clear picture.
Anyone can do the maths even at a rough level - there are 56 billion animals bred and slaughtered each year. Feeding 56 billion animals (many of which are bigger than people) takes a lot more food than a mere 7 billion. Therefore it must take more crops and land to feed them, not to mention the land the animals occupy themselves, as well as the land they destroy by dump their waste products (feces are toxic in those concentrations, where as plant waste, is just compost)
The other thing is that many of these crops are grown in countries where people are starving, using up the fertile land to feed our livestock instead of the people. How f'd up is that?
It's reasons like that why countries like the Netherlands are asking their people to not eat meat more than 3 meals a week.

Productivity and economics:
Countries like Finland have government assistance to switch farmers from dairy to berry. Because they got sick of being sick:
http://nutritionfacts.org/video/dietary-guidelines-from-dairies-to-berries/

The world won't go vegan overnight, and realistically it will never be 100% vegan (people still smoke after all). There will be more than enough time to transition. And surely you aren't suggesting that we should eat meat and dairy to keep someone employed? I don't want anyone to lose their job, but to do something pointlessly cruel just to keep a person working seems wrong.

Animal industries are also heavily subsidized in many countries, so if they were to stop being subsidized that's money freed up for other projects, such as the ones in Finland.

The last bit:
If you eat a plant based diet, just like the cow you'll never have constipation, thanks to all of the fibre
When it comes to enzymes, humans are lactose intolerant because after the age of 2 the enzyme lactase stops being made by the body (unless you keep drinking it). Humans also don't have another enzyme called uricase (true omnivores, and carnivores do), which is the enzyme used to break down the protein called uric acid. As you might know gout is caused by too much uric acid, forming crystals in your joints.
However humans have a multitude of enzymes for digesting carbohydrate rich foods (plants). And no carbs don't make fat despite what the fitness industry would have you believe (as the books above explain).
Appealing to history as well, when they found fossilized human feces, it contained so much fibre it was obvious that humans ate primarily a plant based diet. (Animal foods don't contain fibre).

The reasons why you wouldn't want a whale to eat krill for you is:
1. Food is a packaged deal - there is nothing harmful in something like a potato. But feed a lot of potatoes to a pig, and eat the pig, you're getting some of the nutrients of a potato, but also heaps of stuff you're body doesn't need from the pig, like cholesterol, saturated fat, sulfur and methionine containing amino acids etc And no fibre. (low fibre means constipation and higher rates of colon cancer).
2. Your body's health is also dependent on the bacteria living inside you. (fun fact, most the weight of your poop is bacteria!) The bacteria inside you needs certain types of food to live. If you eat meat, you're starving your micro-organisms, and the less good bacteria you have, the less they produce certain chemicals and nutrients , and you get a knock on effect. The fewer the good bacteria also makes room for bad bacteria which make chemicals you don't want.
Coincidentally, if you eat 3 potatoes for breakfast, lunch, and dinner, you have all the protein you need - it worked for Matt Damon on Mars right?

@transmorpher

It's a little difficult to 'debate' your comment, because the points that you address to me are numbered but don't reference to specific parts of my post. That's probably my fault as i was releasing frustration haphazardly and sarcastically, and that sarcasm wasn't aimed at you. All i can do is try and sum up whether i think we agree or disagree overall.

Essentially everything is a question of 'taste', even for you. There's no escaping our nature, most of us don't drink our own piss, many of us won't swallow our own blood, almost all of us have a flavour that we can't abide because we were fed it as a child. So yes, our decisions are defined by taste. But taste is decided by the food that is available to people, within reasonable distance of their house, at a price they find affordable according to the society around them, from a range of food that is decided by society around them. Your average person does not have the luxury to walk around a high street supermarket selecting the most humane and delicious foods. People get what they can afford, what they understand, what they can prepare and what is available. Our ancestors ate chicken because of necessity of their own kind, their children are exposed to chicken through no fault of their own, fast forward a few generations, and thus chicken becomes an affordable, accessible staple. Can we reach a compromise here? It may not be necessary for chickens to die to feed the human race, but it may be necessary for some people to eat chicken today because of their particular life.

I don't like the use of the phrase 'if i can do it, i know anyone can'. I think it's a mistake to deal in certainties, especially pertaining to lifestyles that you can't possibly know about without having lived them. Are you one of the many homeless people accepting chicken soup from a stranger because it's nourishing, cheap and easy for a stranger to buy, and keeps you warm on the streets? Are you a single mother with coeliac disease, a grumpy teenager and picky toddler who has 20 minutes to get to the supermarket and get something cooking? Or one of the millions using foodbanks in the UK (to our shame) now? I don't think you're willfully turning a blind eye to those people, i'm not tugging heart strings to do you a disservice. Maybe you're just fortunate you not only have the choice, but you have such choice that you can't imagine a life without it. I won't budge an inch on this one, you can't know what people have to do, and we have to accept life is not ideal.

And within that idealism and choice problem we can include illnesses that once again in IDEAL situations could survive without dead animals, nevertheless find it necessary to eat what they can identify and feel safe with.

Yes, those damn gluten hipsters drive me round the bend but only because they make people think that a LITTLE gluten is ok, it makes people take the problem less seriously (see Tumblr feminism... JOKE).

I agree that we must look at what action we can take now - and that is why i keep reminding you that we are not in an ideal world. If the veganism argument is to succeed then you must suggest a reasonable pathway to go from how we are now to whatever situation you would prefer. My "ideal farm" description was just me demonstrating the problem - that you need to show us your blueprint for how we start again without killing animals and feeding everyone we have.

And on that subject, your suggestions need to be backed by real research, otherwise you don't have any real plan. "It's fair to say there is very little risk" is a nice bit of illustrative language but it is not backed by any fact or figure and so i'm compelled to do my Penn and Teller impression and call bullshit. As of right now, the life expectancy of humans is better than it has ever been. It is up to you to prove that changing the diet of 7 billion people will result in neutrality or improvement of health and longevity. That proof must come in the form of large statistical analyses and thorough science. I don't want to sound like i'm being a dick, but any time you state something like that as a fact or with certainty, it needs to be backed up by something. I'm not nit picking and asking for common knowledge to have a citation, but things like this do:

-- 70% of farmland claim
-- 'fair to say very little risk' claim
-- meat gives you cancer claim - i accept it may have a carcinogenic effect but i'll remind you so does breathing, joss-sticks, broccoli, apples and water
-- 'the impact to the planet would be immense' claim - in what way, and what would be the downsides in terms of economy, productivity, health, animal welfare (where are all the animals going to be sent to retire as of day 1?)
-- etc. etc.

Oh, and a cow might get its protein from plants, but it walks around a field all day eating grass, chewing the cud and having sloppy shits with 4 stomachs and enzymes that i don't have................. I'm a bit puzzled by this one... I probably can't survive on what an alligator or a goldfish eats, but i can survive on parts of an alligator or fish. I can't eat enough krill in a day to keep me going, but i can let a whale do it for me...?

Dear Future Generations: Sorry

newtboy says...

Pretty much what @Mordhaus said.

There's no way to sustain the numbers we have today without changing 99% of people's habits, most effectively starting with breeding habits.
With the need for only 10% the power required today, you would never need to use nuclear power at all, or hydro. You could supply it on wind and solar with a small fossil fuel peak power generator system.
The planet MAY survive....but I don't count only extremophile bacteria as really 'alive'. Worst case scenario, we could be Venus 2.0, in my eyes, that's not alive.

diego said:

actually, its not at all like that. the planet has food and land in surplus for everyone, but there is huge waste. Some of it is the price of technology and the modern life style, some of it is avoidable, reckless waste, but its not only a matter of "if there were only less people". That wouldnt make trawling the ocean any less destructive, or nuclear waste any less toxic. The planet is going to survive no matter what, the question is in what form, reducing the number of people on the planet only changes the time it takes to ruin the planet if the people that remain are going to continue irresponsibly consuming and contaminating as before.

Dear Future Generations: Sorry

newtboy says...

*promote some good points.
It's a bit sad to me that he doesn't seem to know or care that overpopulation is the root cause of all these 'problems', because the earth can survive through all the different damages people have done to it if there was only less damage done. We can cut forests without damage, if we only cut as much as we replant AND grow, we can burn fossil fuels if we only burn as much as the forests can filter, etc. If we had <1/10 the number of people doing <1/10 the amount of damage, the planet would likely be fine.
Also...*commercial (since it's an advertisement for standfortrees.org)

Pig vs Cookie

transmorpher says...

What's the difference between a pet pig and a livestock pig though?
They both want blankets and cookies. Or at the very least neither of them wants to stand in a tiny metal and concrete cage and be pumped full of antibiotics, hormones and god knows what else for their short miserable lives. Neither of them want to be bruised because they have only enough room to face one direction their entire lives. Neither of them want their testicles ripped out without anesthetic while they are piglets. Neither of them want to be beaten when they don't eat.

Also, despite what the marketing people say, humans are not omnivores, everything healthwise and physiologically suggests we are somewhere between herbivores and frugivores. It's also backed up historically too by analyzing fossilized poop!

Here is a quite simplified chart, but I think it does a pretty good point of showing how far away we are from typical mammalian omnivores http://www.whale.to/c/10013268_676368449097110_1949968139_n.jpg

I'm not having a go at you, but I just hope you aren't acting according to a few labels that some organisation has set.

makach said:

I respect that.

I would never eat a pet, but omnivore I am.

An Unfortunate History of White Actors Playing Other Races

VoodooV says...

And they explained away Khan's original appearance being transformed into Khanberbatch as just futuristic cosmetic surgery in the prequel comic I think.

But yes, it's still stupid. In their defense, how else were they going to do Khan? The person would have had to have looked like Montalblan otherwise.

But going back to stupid since it was just stupid to reboot the Khan storyline. Cuz yeah, a genetic superman from the 1990s would be a really big help fighting a war in 2200s. Obviously war in the 2200s is exactly the same as it was in 1900, no leap in logic for this fossil to design a hyper advanced starship that dwarfs the flagship of the day...not at all.

The All-Seeing NostraDonald

dannym3141 says...

What the fuck is going on here? Is this real politics? This is an obviously stupid, ignorant man. It's as though he has verbal diarrhea - he just can't stop exaggerating and making things up as though he's a kid in a playground, with no thought for evidence or substance, i'm expecting any minute for him to say that his dad can lift a house, he's been to the moon three times and he's been made Earth President by the alien high council. How the hell can he make so much progress in his bid for the American PRESIDENCY?

"I don't know where i saw the video, but i know i saw it because i have the world's greatest memory"
Those words were spoken in absolute seriousness by a leading presidential candidate for the US in 2015 when justifying a racist comment about muslims. I write this for posterity so future historians are left in no doubt, when the video is long gone, when all we have are fossils of internet text, because our civilisation violently died when President Trump took the west to nuclear war because he thought his dad is better than Putin's dad.

You can trust my memory. Where did i see it? I don't remember.....

@bobknight33 - whereas those right wing comedians have been absolutely killing the ratings as of late. They don't exist because as Chris Rock said comedy should always be punching upwards - so where is the comparison to say whether or not a right wing comedy show would do so much better? Personally i very rarely find Colbert funny, but that's because i don't find him funny, not because i think he's left wing - hence i wouldn't watch his show regardless of politics. It's your burden to prove that his political leanings have anything to do with his ratings.

Bill Nye - 5 Things You Need to Know About Climate Change

RFlagg says...

Yeah, I think that's what the deniers don't get. When 97% of scientist agree that humans burning fossil fuels is the primary driving force behind climate change, they are talking about the increase from what would be natural, to what is happening now. Nobody is claiming 100% of all global warming is human caused, just like nobody is coming for their guns, but the conservative media sells both that way.

Explaining the importance of the speed of the change can be difficult.

Bicimaquinas: Bike Powered Machines

Buttle says...

A generation or two ago I doubt that poor Guatemalans could get fat, regardless of culture, because they simply didn't have access to the surplus energy required. This surplus energy shows up in nitrate fertilizers used for agriculture, powered tools of all sorts, and manufactured goods, like used bicycles.

It comes, of course, from fossil fuels.

A bicycle may seem a simple and primitive device, but just try to build a bicycle chain in your home workshop and you will see that making safety bicycles is possible only in a modern industrial state. It's not surprising that the development of the safety bicycle only barely preceded that of the automobile and the airplane.

The bicimaquina raw material is discarded bicycles from richer people -- nothing wrong with that, it's good, frugal engineering. But it should be borne in mind when plotting the future that hardly used bicycles are not a renewable resource, and require energy and infrastructure to produce.

Bicycling does give one a good appreciation of the value of energy. For example, 125 Watts is a respectable output for a touring cyclist; keep that up for 8 solid hours, and you have one kilowatt-hour. One kW-hr is a day at hard labor. A typical household in the developed world uses the equivalent of the labor of three or four hard-laboring slaves every day.

Of course, those slaves aren't the most efficient. You'll notice that the machines shown all use a direct mechanical drive. They could generate electricity, but that would cost -- multiply a few 90% efficiencies together and pretty soon you're getting nothing done by leg power.

Bicycle drive does allow good power production from human beings, and multi-geared bicycles are adaptable to people of differing strength. Not as much fun as flipping a switch, but easier than turning a crank.

It's plain that cheap fossil fuels won't last forever, indeed they may not last for much longer, and probably will never be available to much of the world at the same level as we currently enjoy in the US or Australia. Will we find ourselves scouring garages and cellars for disused bicycles?

Likely North American influence upon their culture. Many of the poorest in our countries are riddled with pop and fast food, so it makes sense it would be similar elsewhere.

Nuclear energy is awesome

dannym3141 says...

Fusion is well within our reach. It just doesn't have the funding (and therefore the fast research/development cycle) because the oligarchs are not done selling us fossil fuels yet.
