How to Protect the Environment in Our Daily Life
Protecting the environment is very important. We can start by reducing the use of plastic. For example, we can use reusable bags instead of plastic ones. We should also save water and electricity by turning off taps and lights when not in use. Planting more trees is another way to help the environment. Trees clean the air and provide oxygen. Additionally, we should sort our garbage and recycle as much as possible. Finally, using public transport instead of driving can reduce air pollution. If everyone does their part, we can make a big difference.
