It's an extreme solution certainly, but not without merit. I doubt there'd ever be a willing acceptance of such a plan though, so a slightly more realistic solution would need to be moderated some. How's this for dystopian-but-not-quite-genocidal:
Worldwide lottery, a small percentage (total of 500M - 1B maybe) wins the right to live in what will be the new model of the world: something like what we have now, but with drastically reduced usage of non-renewable resources (until they can be replaced completely) and a target of zero negative impact on the environment as a whole. Still some version of democratic (generally at least), freedom of whatnot and such, open travel to the degree that sustainable transportation options allow, all the (again, sustainable) mod cons. I suppose different countries / regions could still run things according to their preferences, as long as the net-zero goal remains.
The other lottery entrants, the non-winners, don't need to die, hooray! They will however live on something akin to reservations, as serfs, without the right to further reproduce. These poor bastards, in exchange for not being outright murdered to save civilization, are to be consolidated into agricultural communes to do whatever they can to regrow the world's flora and fauna until they all eventually die. Their goal is not net-zero, but as far into the positive as possible. It would all be overseen according to some grand scheme(s) to be as beneficial for the overall future of humanity and life on Earth in general as possible.

Probably also unworkable, but preferable to megamurder?

As I understand it, numerous states are changing their electoral rules so all their electoral college votes go to the winner of the national vote count. Not perfect, but it's a start.

Not one single mention who the winners were for best potato battery or volcano experiment.

And the winner of World's Most Punchable Face for the third year in a row....Donny "Treason" Trump.

I want to preface this comment by saying that I am a political independent, and something that might help convince you of that is that I didn't vote for Donald Trump. The reason I didn't vote for him is because I had serious reservations about him considering what I knew about his character. Now that he is president I support him because I respect the office of the President and I pray for him just as I did for President Obama. That doesn't mean I agree with a lot of what he does, or that I am under any illusions about his character. It just means that I know God is working in these circumstances for a greater good.

I know a lot of Christians voted for Donald Trump because they knew he would side with them in the culture wars. And he has, to a large part. But that isn't the issue with me. I do not fight the culture wars even though I find abortion abhorrent and I lament the deepening darkness that pervades our culture. It is moral and spiritual darkness which will eventually lead to the one world government of the Antichrist.

My issue has to do with the church waking up, and stop thinking the solution is in fixing the culture because the culture is influencing the church more than the church is the culture. The solution is to get right with God and show the love of Christ to a lost and dying world.

So, here is the comment:

It's obvious that the entirety of news media is corrupt; if 2016 didn't make that obvious I don't know what would. They pick winners and losers, as supporters of Bernie Sanders realized. They all have a political agenda and will write either negative or positive coverage based on that agenda. They will present a certain slant to every issue which is favorable to their political aspirations. It is patently obvious and I think most of the country realizes this.

So, this outrage over Fox doing what every other news media company has done in the past, is pretty lame. Maybe Fox is better at it than MSNBC but the point is, they both function as the arm of their respective parties, and manipulate their media coverage to brainwash people into believing their worldview.

This is possibly the most Canadian thing ever. The French Canadian town of Saint-Narcisse-de-Rimouski holds an annual snowblower race at their winter carnival with a grand price of a heat pump. 96.7 The River reports this year’s winner was a souped up Honda.

Everybody's singing the same song
It goes "tonight, tonight, tonight, tonight, tonight, tonight"
I never realized these artists thought so much about dying

But truth be told we all have the same end
Could make you cry, cry, cry, cry, cry
But I'm telling you
This is the best news you're getting all week

Oh sure it's ruling the airwaves
What remains of the airwaves
And we're frankly thankful for the market psychology you're hipping us to

And all the hits are saying the same thing
There's only tonight, tonight, tonight, tonight, tonight, tonight
Then life is finite
But shit, it feels like forever
It feels like forever

Oh is everybody feeling the same stuff?
We're all wild
Except for you
And you know who you are
This is a love song

And you're getting older
I promise you this; you're getting older
And there's improvements unless
You're such a winner
That the future's a nightmare
And there's nothing I can do
Nothing anyone can do about this

And oh, I'm offering you a chance to get even
But oh, you know very well the dialect of negation
Sure enemies haunt you with spit and derision
But friends are the ones who can put you in an exile
But that's not right

And you're too sharp to be used
Or you're too shocked from being used
By these bullying children of the fabulous
Raffling off limited edition shoes

And what's it you do again?
Oh I'm a reminder
The hobbled veteran of the disk shop inquisition
Set to parry the cocksure of men's sick filth
With my own late era middle-aged ramblings

Every lover favors the same things
It's all "touch me, touch me, touch me, touch me tonight"
We maybe realize what it is we need before we die

And luck is always better than skill at things
We're flying blind
Oh good gracious
I sound like my mom

But out of the little rooms and onto the streets
You've lost your internet and we've lost our memory
We had a paper trail that led to our secrets
But embarrassing pictures have now all been deleted
By versions of selves that we thought were the best ones
'Till versions of versions of others repeating
Come laughing at everything we thought was important
While still making mistakes that you thought you had learned from
And reasonable people know better than you
That cost in the long run but they don't know the short game
And terrible people know better than you
They're used and abused of the once so dear listener
So you will be badgered and taunted until death
You're missing a party that you'll never get over
You hate the idea that you're wasting your youth
That you stood in the background oh until you got older
But that's all lies
That's all lies
