What would be the consequence to Earth’s ecosystems if the ozone layer were to completely dissipate? Are certain organisms, landscapes, environments more at risk if this were to happen?
What is the difference between primary pollution and secondary pollution? Which is easier to control? Why?
Don’t like any of these questions? Ask one of your own, and then answer it.Note that your question should be substantive, just like your answer, and the question should be in a format that invites further discussion. Avoid questions like “Why are kittens cute?” or “Are sharks vicious?”
