Answer: For one, littering is not good for any type of species, not just humans...
Explanation: Litter can pollute the air that we breathe in, causing other species (animals, plants, etc.) to become sick and ill. Researchers have actually estimated that more than 40% of the world's litter is being burned in the open air, which resulted in toxic emissions being released. Above all, littering has a negative effect on everything. Littering along the road, on the streets or by the litter bins, toxic materials or chemicals in litter can be blown or washed into rivers, forests, lakes and oceans, and, eventually can pollute waterways, soil or aquatic environments.
Stop littering! Save mother Earth!
