Doom yourself to horrific climate change by burning all that carbon and releasing all that CO2. Or power down society, reducing total energy usage around the planet. One leads to ecological collapse. The other is a reversion, in many ways, to poverty.

We have climate change caused by greenhouse gas emissions, mostly from human power and transportation infrastructure. At the same time, we have 2 billion people who live in energy poverty.

Agriculture is the #1 source of deforestation. By some estimates it accounts for 80% of the forests chopped down in the tropics.

I think the environmental movement is now so large and diverse that it's hard to talk of it as a single entity.

We don't have good global policies in place for climate.

Unfortunately, in the environment, I don't see as much willingness to invest heavily in R&D as I do in consumer technology. And that's a pity.

Just like you could dump oil into the Cuyahoga in the 60s and let someone else foot the bill, today you can pump CO2 into the atmosphere and let the whole world foot the bill.
