How does the environment affect a species survival?

I am guessing you mean 'How is the environment our survival?'

Well, basically, we can't live with-out a lot of things: Food, water and heat are just some of them (TV is close, I know!), and with-out them, animals of all sorts, and us humans, would simply die out.

So, if we're polluting the Earth, this means we are slowly destroying the Earth. The cloud of gas building up in the atmosphere is wearing away the beams that stop sun-beams getting to us, meaning that the Earth is warming up rapidly. If we let this happen, we will die from the heat of the sun protruding our nice little Earth.

Global Warming is also causing lots of weather problems, with heavy rain, and then very hot weather. This means that lots of crops all over the world aren't bearing the sudden changes, and dying. This then means that we aren't getting as much food on our plates.

Remember I said (^) that we need food+water to survive? Well, I've covered food, but what about water?

Well, that's the same kind of thing as food. The weather is changing the amount of water we can take from places with-out ruining the surrounding area.

I hope I helped you,
