Summary
In the article "Diet For A Healthier Planet", the author discusses a recent study conducted by the Potsdam Institute for Climate Impact Research that determined if people use less meat and dairy in our diets, it could help reduce the agricultural greenhouse gases by as much as 80% by 2055. The researchers found that if meat and dairy consumption patterns remain constant or increase, agricultural emissions will increase significantly. On the other hand, a 25% reduction over the next 40 years would help bring agriculture emission levels down to where they were around 1995. Agriculture greenhouse gases are mostly caused by waste from livestock and synthetic fertilizers. Also, around two-thirds of nitrous-oxide emissions come from agriculture, and most of that results from either raising animals or producing the feed used to raise them. Although not nearly as much methane or nitrous oxide is released into the atmosphere as carbon dioxide, they both contribute substantial amounts to greenhouse gas emissions.
Evaluation
While I was reading this article, I couldn't help but wonder where the author was getting the information from. It didn't explain it very well in the beginning of the article, but towards the middle it started listing sources and telling where the author got the information from. I thought that the article is a reliable source, and I would probably use it in the future. I definitely learned some things from the article that most sources I read didn't mention. It makes sense to me that waste from the animals or from producing the feed for them will produce nitrous oxide. Also, I thought that that the suggestions the author and dieticians gave to help people with their diets were very realistic, and not just "over the top" information. Overall, I thought this article was pretty well written, and the author is a reliable source.
