Unless we change our food choices, nothing else matters. Because it is meat that is destroying most of our forests. It is meat that pollutes the waters. It is meat that is creating disease which leads to all our money being diverted to hospitals. So, it's the first choice for anybody who wants to save the Earth.

Cows provide approx 100 million tonnes of dry dung a year costing Rs 5000 crores which saves 50 million tonnes of firewood which again means that many trees saved and more environmental damage prevented. It is calculated that if these 73 million animals were to be replaced, we would need 7.3 million tractors at the cost of 2.5 lac each which would amount to an investment of 180,000 crores. In addition 2 crore, 37 lakh and 50 thousand tonnes of diesel which would mean another 57,000 crore rupees. This is how much we owe these animals, and this is what we stand to lose by killing them.
