A vegetarian diet is often praised for its health benefits. What most people are less aware of, however, are the effects that a vegetarian diet, compared to a non-vegetarian diet, can have on the environment.
How can eating meat have a negative effect on the environment? For a start, all livestock animals such as cows and pigs release methane gas by expelling wind from their bodies. Many environmental experts now believe that methane is more responsible for global warming than carbon dioxide. Another way in which meat production affects the environment is through the use of water and land.
Many people now see the benefits of switching to a vegetarian diet, not just for health reasons, but also because it plays a vital role in protecting the environment. However, some nutritionists believe a vegan diet, which excludes all products from animal sources, such as eggs and milk, can be deficient in many of the necessary vitamins and minerals our bodies need.
Today, more people may realize that more of us will need to become vegetarian in order to preserve the environment and to help the human race to survive. 【題組】50 Which of the following can be concluded from the article?
