There are many things we can do to help save the planet. First, the most simple thing we can do: Pick up your garbage. It sounds easy, but will you really commit? You can pick up garbage, any garbage you can see on the streets, or in your community. Then, put it in the correct garbage can. If it is paper, or something related to that, then dispose of it in the recycling bin. If it is organic, such as a banana peel, or apple skin, dispose of it in the organic bin. Then, if there is any extra garbage you cannot recognize, then you can dispose of it in the normal bin. ( eg- plastic).
Then, if you are going a short distance, please try walking, or taking a cycle. Try refrain from using a car because cars emit gases like carbon monoxide and carbon dioxide. Do you know they are making cars which are battery operated? So those cars will emit no harmful gases. Driving all those cars will do no harm to the environment. So please try avoiding driving a car that uses petrol and diesel.
Those are just 2 of the million things you can do to save the environment and help prevent global warming. Spread the awareness, tell people when they are doing something wrong like littering. Doing it by accident is ok, but doing it knowingly, is just not cool. Ask people about global warming. Learn more about it from the internet. I also have a little challenge for you: for 1 week, pick up any garbage you find, and put it in the trash bin. No matter how gross it is. If you do it, amazing job. Pat yourself on the back for the good work!
