　　Let's try our best to protect our environment together!‍

We had a discussion on ways to protect our environment. Mary suggested that we should bring our shopping bag when we go shopping. Kate said that it's better take a bus or walk when we go out and drive our cars less. Mike suggested that we should put more teeth on our laws on environmental issues like waste disposal of factories which put our water and air environment at risk. Jack thought it's important to do refuse sorting - identify, collect and sort discarded items suitable for recycling. Tom suggested that we use both sides of the paper instead of one. By doing that, we protect our trees. Finally I said that we use our water wisely. Without water, there is no life.
In conclusion, we came up with a slogan - Let's try our best to protect our environment together!
