It is a country with high mountains and clean blue lakes. It is beautiful, and we should try to keep it that way. In Switzerland, things like glass, plastic and paper are separated into different groups and then recycled. In fact, Switzerland has one of the highest levels of waste recycling in the world--it successfully recycles more than 50% of its total waste. I learnt about an organization for recycling clothes. It collects old clothes from all over the country. Some of the clothes are sold in charity shops, some are given to people in need, and others are sent to factories for recycling. My family and I often send our old clothes and shoes to this organization. Our government has many laws to protect the environment.There are strict rules about how many trees people are allowed to cut down as well as laws to control air and water pollution.When people break these rules, they will be punished. For example, if we drop litter in a public place, we will be fined by the police. Nature is our greatest treasure. We depend on its rich resources to live, so it is important for us to protect it wisely. Luckily, we have already started to use energy from the sun, wind and water.These new types of energy will never run out. Moreover, they produce little pollution. Tomorrow is 5 June, World Environment Day. Lots of activities and events are going to be organized all around the world to celebrate this day. What are you going to do for nature and the environment?
