You may not have realized that eating vegan can have a positive impact on the environment. By going meat-free, you'll reduce your carbon footprint and save water, land, and energy for other uses. The World Health Organization (WHO) has stated that climate change is one of the biggest health threats of our time. As greenhouse gas emissions continue to rise, so does the global temperature—and higher temperatures lead to higher rates of heat-related illnesses like cardiovascular disease, respiratory distress, and kidney failure. This makes it all the more important to reduce our greenhouse gas emissions whenever we can—and following a vegan diet is one way to do so!
