Switching to a plant-based diet certainly has a positive effect on the environment.

But, I wonder if it is enough to stop a climate breakdown. I believe that automobiles and factories contribute the most to climate change. According to EPA[1], CO2 from fossil fuel and industrial processes account for 65% of global greenhouse gas emissions.

However, every little bit helps and thus I encourage folks to follow a plant-based diet for environment and other reasons. (I've been vegan 20+ years.)
