Pre-reading
What do you think a "green country" means
I think a green country means a country with fresh air, clean water and beautiful natural surroundings. People there live in harmony with nature.
Switzerland: a green country
I love Switzerland. 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 strict laws to protect forests and control pollution. When people break these rules, they will be punished.
For example, if we drop litter in a public place, we will be fined.
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 types of energy produce little pollution and will never rur out. They are going to be used more widely in the future.
Tomorrow is 5 June, World Environment Day. Countries around the world will organize lot to celebrate it. What are you going to do for the enviroriment Remember that everyone can do something to make a difference!
