Food And Global Warming

Sep 29, 2011 in , ,

Most of us are omnivores – that is, we eat both meat and plant foods. While we need a healthy balanced diet, we should also be aware that consuming meat has a very large impact on the environment.
In the difference between eating meat and plants, the first thing that stands out is that plants such as grain only need water and fertiliser. Meat, on the other hand, comes from animals who need to be fed grain – the same grain that people could eat. It takes 4kg of grain to produce just 1kg of beef and those 4kg could be used to feed starving people instead – such as those in the Horn of Africa who are facing a terrible famine right now.

Production of meat is also a significant contributor to global warming, and according to, “Producing 1kg of beef results in more CO2 emissions than going for a three-hour drive while leaving all the lights on at home.” The accumulation of this comes partially from the transport of their feed, and the carbon that they exhale. Along with carbon, cows also emit methane, a gas that degrades the ozone layer. Imagine, just by eating steaks, we are contributing to global warming, and to the decline of our environment.

The most obvious thing that we can do is to become vegetarian, but there are easier ways to make a difference. For instance you skip consumption of meat one day in a week, or simply cut down the amount of meat in your diet in general.
Doing so can bring health benefits too.

Something you must remember, no matter what you eat, is to check the source of your food. It’s best to get food that has been produced locally, because you are cutting down on the carbon emitted through transport, while supporting your community at the same time.

Whatever your food choices are, please keep the environment, and your health, in mind.
