One critical issue the effect of water has on humanity is that the polar ice caps are melting. This is bad for several reason. One, this is fresh water stored in ice that just melts and falls into salt water. There is already a scarce amount of fresh water for humans to use and with the polar ice caps melting it leaves us with less fresh water to use. The polar ice caps melting also show us how we are emitting too much carbon dioxide into the air. Since 1973 to now, about half the polar ice caps are left. If we do not lower the amount of carbon dioxide that we emit, we are lowering the amount of fresh water that we can access in the polar ice caps.
