News that scientists are 95% certain humans are the “dominant cause” of global warming since the 1950s is alarming.

Future generations will shake their heads in disbelief that we knowingly went on wrecking the planet: it will be them, not us, paying the price.

Incredibly, more than 70% of all agricultural land in Britain is used to feed animals. Rearing animals to make meat, dairy and eggs is a terrible waste of resources.

The same amount of land can feed up to ten times as many people if you grow crops on it rather than graze animals or grow animal feed. This is all the more shocking when you consider that world hunger continues unabated and millions of people each year die of starvation. Yet in some countries, crops are grown to feed animals while the people there suffer and die from hunger and disease due to a lack of food.

Animal farming is also a huge waste of water. It takes 1,000 litres of water to produce one kilo of wheat, yet it takes 100,000 litres of water to produce one kilo of beef.

It also causes soil erosion and land degradation. Methane gas from farmed animals contributes to global warming, and waste from intensive factory farms is one of the main causes of water pollution. It is also responsible for the disappearance of the rainforests to make way for cattle ranching and growing crops to feed farmed animals.

Therefore, switching to a vegan diet would help stop global warming. It would also benefit our health and the animals.
