Its aim is to remind people to protect the environment. It has a different theme each year. Theme for this year’s World Environment Day celebrations is Think, Eat, Save. According to the UN Food and Agriculture Organization (FAO), every year 1.3 billion tonnes (公吨) of food is wasted. At the same time, 1 in every 7 people in the world go to bed hungry and more than 20,000 children under the age of 5 die daily from hunger.
If food is wasted, it means that all the resources (资源) and inputs (投入) used in the production of all the food are also lost. For example, it takes about 1,000 liters of water to produce 1 liter of milk and about 16,000 liters goes into a cow’s food to make a hamburger.
So think before you eat and help save our environment!
For example, you may choose foods that have less environmental impact (影响), such as organic (有机的) foods that do not use chemicals (化学制品) in the production process. Choosing to buy locally can also mean that foods are not flown halfway across the world and therefore limit emissions (排放).
Tasks: 1. What is the theme of World Environment Day this year?
2. Why should we think before eating? Because people waste a lot of food every year, which has bad impact on the environment. What can we do to clean up the world?Please design some activities for World Environmental Day.
