3. Stop wasting food
This may not be as obvious, but in reducing food waste we reduce methane emissions from landfills and lower our overall carbon footprint. Potential pollution is involved in every step of the process, including the growing, manufacturing, transporting, and selling of the food -- plus when it's eventually taken to the landfill, which are themselves disastrous for the environment. According to the EPA, roughly 95% of the food we throw away -- 38 million tons in 2014 -- ends up in either landfills or combustion facilities.
This is another one that's pretty easy to address. For instance, before buying more food, use what's already in your refrigerator. Really think about how often you'll be eating out vs. cooking and shop accordingly. With fruits and vegetables, it helps to store them in proactive ways, like freezing or canning. Also, as a lot of fruits ripen, they give off natural gases that make the fruits around them spoil faster, so it helps to store bananas, apples, and tomatoes separately. Also, eat less meat. The industry's current set up leads to a huge amount of greenhouse gas emissions.
Finally, if you have food you're not going to use, donate it to a food bank or food pantry. It puts the food to use and& help those in your community who are less fortunate. We'll get into this more in a minute, but you should also consider composting when you can to avoid sending more waste to the landfill than is necessary.
