The five main points

Please view Eating for the environment for ongoing updates of global statistics.

1. Limiting the consumption of meat and dairy:

Even if we don’t feel completely ready to cut out all animal products from our diets, it will make a significant difference to the planet if we all limit the amount of meat, dairy, fish, and eggs that we purchase.

2. Buy only Organic corn and soy.

About 65% of the corn and 75% of the soy grown in the U.S. is now Genetically Engineered. Not only does corn require a massive amount of pesticides but most of it is grown just to feed factory farmed livestock. Because of the corn surplus we are now using high-fructose corn syrup as a sweetener in almost every product on the market. A direct result of this is the unprecedented obesity we see in our children and the diabetes epidemic that now affects over 20 million Americans.

3. Eat local

Using your purchasing power to support local farmers is one of the best ways to help both the environment and your immediate community. By eating foods that are grown within a 100-mile radius of where you live you are not only living closer to how nature intended but also preventing the unnecessary use of oil needed to ship fruits, vegetables and meat thousands of miles in all directions.

4. Buy a water filter and limit your use of bottled beverages.

In the U.S. alone we use approximately two million plastic bottles every five minutes and 270 million aluminum cans each day. The amount of oil needed to make these plastic bottles equals about 15 million barrels a year. Most plastic bottles do not get recycled, but keep in mind that while recycling is preferred it is not possible without still more use of fossil fuels. Moreover, it takes 3 liters of water to manufacture just 1 liter of bottled water. So buy a stainless steel thermos and re-use instead.

5. Grow your own food or join a CSA (Community Supported Agriculture)

If you have the space grow your own fruits, vegetables and herbs. If not, join a CSA (Community Supported Agriculture) and shop at local farmer's markets whenever possible. By joining a CSA you will be supporting sustainable family farms whether you live in a big city or small town.
