By cutting down of the factories that polluate the air so much, we could have cleaner air, that would contain more oxygen. The atmosphere wouldn't be getting warmer from all the fumes and the icebergs wouldn't be melting anymore, resulting in less chances of the ocean levels rising.
Also, it is very important that we stop harming the nature surrounding us, since it represents great importance to our future. Therefore, we need to stop littering, stop cutting down forests, plant more trees that would help rise the oxygen level, and, in general, try to be more environment-friendly.
