Wanna know how?

Then keep watching.

What contributes more to climate change than all of the world 's planes, trains, and automobiles combined?

Farm animals.

According to the UN, raising animals for food is one of the largest contributors to greenhouse gas emissions.

And that's only the beginning.

As demand for animal products is growing, animal agriculture has gobbled up more and more water, energy, crops and land.

Over recent decades, vast expanses of native habitat around the world have been cleared to grow crops to feed animals.

Most of them in factory farms.

Animals are fed about 6 kilograms of plant protein to produce just one kilogram of animal protein.

The numbers just don't add up.

Factory farms use more food than they produce, which leaves less food for everyone else.

At a time when globally, nearly 1 billion people are suffering from malnutrition,

one-third of the world 's edible cereal harvest is being fed to farm animals.

That cereal would be enough to feed about 3 billion people.

Everyone from leading water and climate scientists to OXFAM and World Vision, and even the United Nations agree

that by eating less meat we can reduce pollution, save resources, and combat world hunger.
