Education is the backbone of our future as a society of growth in all things that will make life better. If we as a society don't take the education of our youth seriously, we are practically ruining our future. Education gives us knowledge of the world around us. It develops a new perspective of viewing life. Imagine a world of politics with uneducated people. Imagine a government without educated rulers... looking at history with a knowledgable perspective helps make good decisions. A wise man once said, "Those who Do Not Learn History Are Doomed to Repeat it" (George Santayana).
I would have to go with Sewage mostly because it smells and because it can really hurt the environment. Plants can die and it just is gross to smell. So this would definitely pollute the earth. I hope this helped! :D
