We have to prove to the disinherited majority of the world that ecology and conservation will not work against their interest but will bring an improvement in their lives.

Biofuels such as ethanol require enormous amounts of cropland and end up displacing either food crops or natural wilderness, neither of which is good.
The most interesting biofuel efforts avoid using land that’s expensive and has high opportunity costs. They do this by getting onto other types of land, or taking advantage of byproducts that aren’t used in the food chain today, or by intercropping.
Climate change is such a huge issue that it requires strong, concerted, consistent and enduring action by governments.
By the time we see that climate change is really bad, your ability to fix it is extremely limited… The carbon gets up there, but the heating effect is delayed. And then the effect of that heat on the species and ecosystem is delayed. That means that even when you turn virtuous, things are actually going to get worse for quite a while.
It’s not as though we can keep burning coal in our power plants. Coal is a finite resource, too. We must find alternatives, and it’s a better idea to find alternatives sooner then wait until we run out of coal, and in the meantime, put God knows how many trillions of tons of CO2 that used to be buried underground into the atmosphere.
Climate change is a terrible problem, and it absolutely needs to be solved. It deserves to be a huge priority.
Now, we put out a lot of carbon dioxide every year, over 26 billion tons. For each American, it’s about 20 tons. For people in poor countries, it’s less than one ton. It’s an average of about five tons for everyone on the planet. And, somehow, we have to make changes that will bring that down to zero.
The reason we should do a carbon tax is because it’s the right thing to do. It’s economics 101, elementary stuff.
