They have many strict rules about protecting nature. One important rule is about waste sorting. People must separate their rubbish into different groups, such as glass, paper, plastic, and kitchen waste. They cannot throw all the rubbish into one bin. If they break the rules, they will be fined. Another interesting fact is that Switzerland recycles a lot. About 70% of their plastic bottles and 90% of their glass bottles are recycled. They also try to reduce the use of plastic bags. When people go shopping, they often bring their own cloth bags. However, there is a big problem: nuclear waste. Nuclear power stations produce cheap energy, but the waste is dangerous. The government is still looking for the safest way to deal with it. In schools, students are taught to "reduce, reuse, and recycle" from a young age. They know that being eco-friendly is not just a choice, but a duty to protect their home. 1.
