ERIC SCHECHTER—But exponential growth and tipping points are just descriptions of how fast. How are humans causing global warming? Materially, the three biggest ways are fossil fuels, deforestation, and cow farts.
Yes, cow farts. We humans, especially in the wealthier countries, are eating a lot of beef, mostly from Concentrated Animal Feeding Operations. CAFO cattle don’t get to graze on grass; instead they are fed cheap grains. This unnatural diet produces a great deal of methane as a side effect. (Pig shit too, to a lesser degree.)
