One of the biggest environmental issues facing the world today is global warming. While its affect on weather patterns, ice caps and rising ocean levels is largely understood, less clear is its impact on our food supply and personal health. Jia-Rui Chong, staff science writer for the Los Angeles Times, cautions that rising global temperatures are changing the food we eat, from increased bacteria levels in seafood from warmer waters to higher carbon dioxide levels that impact the nutritional value of rice and wheat. Global warming also affects human health, as higher concentrations of pollen aggravate allergies, and warmer temperatures promote the growth of diseases and bacteria.
