A study in 1985 found that non-vegetarians are almost twice as likely to develop them as vegetarians. Meat eats the rainforest. Tropical rainforest destruction is a huge environmental problem. The forests of the world are being felled, partly as a result of loggers and our expanding human population, but also to create pasture lands to rear livestock. Millions of acres of life-sustaining forest continue to be felled to create cattle ranches and to grow feed for livestock.
Vegetarianism reduces methane.
Methane gas is one of the key gases that is polluting the atmosphere. This is the result of the sheer numbers of cattle bred around the world. Ozone layer depletion is caused partly by the huge quantities of methane gas emitted by livestock. A depleted ozone layer results in higher rates of ultraviolet B radiation and increased incidences of skin cancer. Help our suffering seas.
