Climate change is not the only major environmental problem facing the world. Just as serious, if not more so, is the problem with maintaining biodiversity. Each day, as man as 150 species go extinct according to the Convention on Biological Diversity. This is largely due to wild habitat being destroyed in the name of animal agriculture (which also happens to be a leading cause of climate change). How can we stop such a calamity? Fortunately, a major part of the equation is to stop eating animals and get all of our calories from plants. Millions and millions of people are already doing this. We just need to convince everyone else to switch.
