There is an environmental impact that comes with consuming an animal-based diet. The United Nations said over ten years ago that climate change is from carbon footprints.

When we think of a carbon footprint we think about the energy sector – fossil fuel, the transportation industry, but we never think about livestock.

The UN published a report that said the emission from the livestock industry meaning cattle, goats, pigs, all the livestock animals – they produce collectively more carbon greenhouse gas than transportation.

“I remember when I saw that I’m like no way. I thought that was a typo. Did I misread that? I mean how could a cow be the same as a car. But as it turned out the cow is way worse than a car in terms of emission because it doesn’t just emit carbon dioxide, it also emits a type of gas called methane, which is 20-30 times worse in greenhouse effect than CO2.”

Cows emit this gas through farting and burping on a daily basis.

The second problem caused by these animals is that they need to consume a lot of food and water in order to grow. You need to feed them before they are fed to us.

“For the same piece of land that can feed a hundred people if you simply grow plants or vegetables or fruits, you can feed only 1/10 or even 1/20 the number of people if you grow food to feed and raise the animals that are then to be fed to us.”

Any time when we are talking about water consumption, land use, food efficiency, food production efficiency, and greenhouse gas effects, meat is always at least ten times if not 20-30 times worse than a plant based diet.
