Thanks primarily to human caused climate change, the earth is on the cusp of mass...extinction.
And yet we find you on the internet burning up electricity to post about this topic, using a computer which also uses electricity and whose production released quite a bit of noxious pollution into the environment.
Instead of being a hypocrite here is how you can productively work to fix the problem. Throw away your computer, preferably via recycling, call your power company and cancel your electricity service. Get rid of your car, protest local mass transit for using metal vehicles powered by technology because metal refining produces pollution as does every type of fuel system, even solar, which could power that vehicle.
Walk everywhere. If your employer uses power during the work day then quit your job because you don't want to be an enabler of horrible practices like using electricity.
Now if your diatribe here is just cheap reputational conspicuous consumption meant to broadcast to us all how much you CARE!!!!!! and you're not actually living your life in a cave, then never mind all of the good advice I just gave you. Normal people know how to tune out liberals who are publicly preening like peacocks about how concerned and enlightened they are about issues.
You know even if I did all of those things, the damage is already done. In less than a century, much of the earth will not be habitable.
Once again, bullshit. Ehrlich, who is one of the main sources for this crap, said (back in the early 1970's) that by the 1980's billions would be dead and most of the Earth would be uninhabitable. As you can no doubt see, he was flat assed wrong then, and he and they are flat assed wrong now.
What astonishes me is you claim to be an educated thinker, yet you believe predictions from people who have a worse prediction rate than KNOWN charlatans like Jean Dixon.
Just imagine that billy, PSYCHICS are better at predictions than your precious "scientists"...... And by a huge amount.
