Without oxygen, life cannot be sustained as it is an essential reactant in the respiration process. So the evolution of photosynthesizing bacteria increased the amount of oxygen in the atmosphere through converting water and carbon dioxide into oxygen with the help of sunlight. This provides a suitable environment for plants and vegetation to grow; plants also photosynthesise so they encouraged the increase of oxygen in the atmosphere even further, sustaining a suitable environment for the Animalia kingdom to evolve. Thanks to this, we now have a huge range of different modern species of animals and plants.

Hi there!
With humanity's constant burning of fossil fuels, large amounts of carbon dioxide get pumped into the atmosphere.
Under normal circumstances (without humans), greenhouse gases are good, as they help keep heat energy in, much like a blanket.
Now, with such large amounts of carbon dioxide, too much heat is being kept inside of this blanket. Our ice caps are melting, threatening the survival of many species of animals. Along with their melting, sea levels are rising (and will keep rising).
With our increasing population, the last thing we can afford is to lose land as well.
Hope this helps.
:)
