Answer:
Pollution and Habitat Loss
Step-by-step explanation:
Pollution has been a big problem in the US from the late 1950s to the early 2000s. Of course, people have made electric charged cars, but they aren't sold as well as gas-run ones because of the fact that there aren't many electrical gas stations. With that being said, pollution isn't JUST because of cars. Believe it or not, 86% of pollution in the US is because of New York! Yes, New York! The big.... Uhhhhh..... I don't know its nickname... But anyway, that's not the point. The point is that New York has many factories and places that run on gas and nuclear energy.
How To Stop Pollution
Alright, I'm going to say it now. YOU CAN USE garbage FOR ENERGY. yeah! you can. It's called thermal energy! You basically decompose the trash and use it as electricity. People could also use solar panels, and if you want to know how they work, just comment below and I'll answer that, too. There also is water energy in places like Tennesee, as water is used for electricity.
Habitat Loss
So... Everybody cares about the cute little bunnies and rabbits, right? And don't forget about the cute little sunflowers that are blooming in summer!
Well, people are cutting down trees to make more homes and cabins, and materials for... materials.
How to stop Habitat Loss
I'm not saying that people can't cut down trees. That they can't touch even one part of an animal's habitat. But I AM saying that they can find a deserted place with no animals and use that as their wood\stone\you-know-what-it-is- refinery! This is unfair to animals to bombard their homes. SO STOP IT!!!!
