Oceans and seas are very important for humankind. Oceans and Seas give us water, food, energy, etc. Plastic affects the Oceans and seas and we need to do something to keep the oceans and seas clean. We need to throw our trashes in the right trash bin. Use fewer plastic products. Go to a local river with your scout's group and do a clean-up project. And to make awareness of how plastic affects the oceans and seas.
