Your Diet and Climate Change Are Connected: What You Eat Matters

Greenhouse gases drive global warming, which threatens biodiversity, ecosystems, and human health. A significant percentage of these disastrous gases come from human food systems: one-third of the worldwide total. This includes every step of the process – from land clearing to make way for farms to producing (raising and harvesting animals and plants) to processing, packaging, and shipping to the food as waste sitting in a landfill.

However, there are ways to improve many aspects of the process to generate fewer emissions. Your choices cause the improvements. For example, what you decide to eat and how much food you waste can either increase or reduce your contribution to global greenhouse gas emissions.

And it’s not as daunting as it sounds. Researchers from Tulane University even show how you don’t have to alter your diet entirely to make a difference. You can dramatically minimize your carbon footprint by simply substituting particular food items. The findings point to beef as the item with the greatest negative environmental effect.
