Global warming or Climate Change is the biggest problem human civilization has ever faced. There are three main divisions in Climate change: Industrial pollution, Car pollution and Animal pollution. People are choosing to eat 70 billion animals every year which is at least 30% of the problem. One study states all the factors add up to 51% of the problem with animals for food. The obvious solution is a plant-based diet. Jesus and Mary were kosher vegetarians. The biblical, historical and scientific evidence is summarized showing that they were vegetarians. They are models to follow since major change is needed in the area of food people eat which affects climate change.
