So Much CO2 That Trees Can't Save Us
I guess we should just give up reducing emissions, and enjoy these last few years, then, huh?

Africans started slavery
Misleading title, otherwise it would be a good post. The slave trade of the 1700's would never have grown into what if became if there were not buyers.
@newtboy, you are correct. Slavery indeed long predates the trade of Africans across oceans. Though, it probably didn't start in Mesopotamia because it was probably happening a little bit everywhere there were tribes that were aggressive with each other.
When slavery is thought of in a modern sense, we tend to think of the slave trade during the early stages of the industrial revolution.
And indeed, members of different tribes were more or less kidnapped and brought to the coast by coastal tribes, where they were sold to ships, which usually originated in Europe or N. America.
One of the busiest ports for the slave trade was Dakar, Senegal. The kingdom there would collect people, to take to Goree Island where they would be later loaded onto ships.

Why you should never pour grease down the drain
If your back yard is big enough....
Not in this rural area.
Why you should never pour grease down the drain
Should go to your city compost system, not the trash. You city does have a compost system, right?

@5:35 -- Remember "LABOUR shortage" is really an industry term for "WAGE shortage."
All labour shortages are solved by increasing wages and/or working conditions. Only when a company in unwilling to do so do they complain about labour. This is often used as an excuse to bring in foreign workers or robots.
The term robot is from Czech robotnik meaning "forced worker."

Rethinking Nuclear Power
I guess I'm lucky enough to live in a country where less than one-fifth of the electricity is generated by coal. So I don't much think of coal vs. nuclear in terms of the cancer risks as such. I'll never be close enough to the fuel of a nuclear reactor. And I'll likely be exposed to more toxicity from traffic than coal plants.
Also, our CANDU reactors can be powered by decommissioned bombs.
"CANDU reactors are unique in that they use natural, unenriched uranium as a fuel; with some modification, they can also use enriched uranium, mixed fuels, and even thorium. Thus, CANDU reactors are ideally suited for using material from decommissioned nuclear weapons as fuel, helping to reduce global arsenals."

There is still spent fuel to be managed, which isn't trivial, but I'm okay with at taking a few bombs out of circulation in the mean time.
Comparing coal and nuclear is like choosing between lung cancer or brain cancer, when there is a option to have neither.

Rethinking Nuclear Power
I used to be anti-nuclear. The basis for this was one part "oh no, meltdowns!" and one part anti-war. The second part of this concern happened when I learned that the material in warheads is refined in nuclear reactors.
As I continued my research I learned that newer reactors can be built that do not enrich weapons-grade material. They can't be used for bombs.
With the new reactor technology, I was left with only the concern around meltdowns. Even with older technology, meltdowns are very rare. Newer technology---like what's mentioned in this video--is even safer..
Now, I'm an old hippie, and I still prefer solar and wind (in my ideal world) but my concern over nuclear was pretty much put to rest with all that I've learned.
As long as the powerplants are designed in such a way that they do not create material that can be weaponized, I'm pretty much okay with it.
