Question

5．Making greener choices and encouraging healthy lifestyles can promote your health and benefit the environment．Here are some guidelines to follow：
Choose foods thoughtfully
Americans have never had such a variety or abundance of food to choose from．Besides so many choices，we now hear about our"food print"，the amount of land needed to supply one person's nutritional needs for a year．Do we buy cherry tomatoes from Mexico or tomatoes grown locally in a hothouse？Do．we get the Granny Smiths from the fanners'market or the supermarket？Is organic produce healthier for us and the planet？
These are very complex issues that require analysis of many criteria，including the energy used in producing and transporting the food，as well as the type of soil and methods of raising the food．
Despite the complexities，there are some general guidelines you can follow．For instance，eat less meat or eat low on the food chain．Your doctor may have recommended you to restrict your consume red meat because of its too much fat content．Beyond th at，there are environmental reasons，too．Raise food animals contributes substantially to climate change because a meat-based diet requires more land，energy and water than a plant-based one．
Drinking plenty of fluids is significant during hot weather or when exercising．But is bottled water the way to go？You may not think so when seeing the true costs．Based on a survey，manufacturing the 30-plus billion plastic water bottles can produce more than 2.5 million tons of carbon dioxide and use here times the amount of water in the bottle．Adding in transportation，the energy used comes to over 50 million barrels of oil equivalent （等價(jià)物）．Consequently，skip the bottled water and drink tap water，both at home and at restaurants．Additionally，bottled water is not necessarily cleaner than tap．
