Let's fight global warming
Global warming is a very crucial thing in the world, because of this ice is melting in the antarctic causing the polar bears to be homeless, eventually in the world there will be no polar bear, lots of polluting air and heat everywhere.
We burn fossil fuels and use lots of oil just for our own well being, we use it in cars,stoves,campfires etc. But even for us we have some disadvantages, for e.g the smoke coming from the fossil fuels can go into our lungs and damage it permanently.
