| What are the sources of CO2? |
Newmark: It's coming from a variety of sources including burning of fossil fuels, such as coal, oil, and natural gas, and from agriculture. But people don't focus on agriculture. They say that we need to switch to wind and solar energy. And, of course, we should transition from a fossil fuel-based energy system to clean energy. But we fail to confront the reality that it is the agricultural malpractice of current farming and ranching systems that contribute to more than half of human-caused CO2 emissions. Food and textile production are contributing billions of tons of CO2 each year.
The worst part of the challenge is that if we were to stop all CO2 emissions into the atmosphere--not one new molecule--that won't do anything to abate the climate crisis. We are already over 400 ppm and we need to get back to 350 ppm. Ideally we would like to get back to the pre-industrial era levels of 275 ppm.
