1. the earths water systems are thrown off balance, more extreme weather events
2. C.) <span>Man-made pollutants causing increased levels of carbon dioxide. </span> As the Earths population grows there is more demand for certain things and even more demand for what creates those products that lead to companies building large factories that create carbon dioxide and other man-made chemicals
3.) A and C are correct but it would have to depend.
With the Earth warming up, temperatures all over the world is changing, for example, over the arctic the ice is melting at a faster rate than it did years before causing the sea levels to rise. with out the ice to deflect light off the surface of the Earth more heat is kept inside the atmosphere( also melting the ice).
i would say more but i cant put it into words
Would have to say to diminish the use of man-made pollutants. And find other ways to produce energy. dont know what else to say
