Earth Day is a special day to make efforts in order to protect the environment. Thus, these are some tips to save our planet. Firstly, we must throw our rubbish in the dustbin. Besides, we should pick up litter in the ground. Moreover, we should organise cleaning campaigns to encourage people to clean the city. In addition, we should recycle and reuse the paper and plastic bottles. Finally, we should use the bike /bicycle more often instead of cars because cars are the main source for air pollution.
