He wrote: “…there are so many great alternatives, for instance, in Italian cooking, so many of the dishes are vegetarian already and Thai and Chinese cuisine are the same". McCartney points out: “…livestock industry as a whole was responsible for more greenhouse gas emissions than the whole of the transport sector put together…The Livestock industry produces gases that are extremely dangerous for the future of our environment…Livestock production is the largest source of water pollutants".
Former United States Vice President Al Gore is listed as one of the supporters of “Meat Free Monday" initiative. McCartney further says that number of schools in United Kingdom, town of Ghent in Belgium, and Sao Paulo (Brazil) have already done this. “…we cannot leave this important issue to the politicians of the world… it is once again left to us, the people, to do it ourselves", he argues and adds, “Next Monday - don"t eat meat and do your bit to save this beautiful planet of ours".
Hindu statesman Rajan Zed, in a statement in Nevada (USA) today, pointed out that Hinduism promoted strict vegetarianism insisting on ahimsa (not harming living creatures) and non-killing, and renouncing animal slaughter and meat eating. It suggested taking of sattvik (vegetables, fruits, etc.) and avoiding rajasik (eggs, etc.) and tamasik (meat, intoxicants, etc.) foods, Zed, who is president of Universal Society of Hinduism, argued.
