Answers
Answer:
your answer is Polluted
Answer:
Undoubtedly, over the last one hundred years, humans have introduced a significant number of chemicals into the environment. While some chemicals are designed to get rid of weeds and pests, a significant amount of chemicals are waste from industrial and agricultural processes. The improper handling of chemical waste has resulted in oceans and the world's water supply being treated like sewage or toxic waste dumps.
Explanation:
While it may seem fine for industrial plants or manufacturers to dispose of two inert chemicals, when those chemicals are mixed the result could be a serious pollutant to the water supply. As streams, rivers, and oceans become polluted, aquatic life can suffer as well as humans. Since water accounts for up to 60 percent of human bodies, it's important for chemicals to be disposed of properly and not end up in the water supply.
Even if you believe the chemical you are throwing down the drain is fine on its own mertis, what if your neighbor is thinking the same thing and the two chemicals combine in the sewer system?
