Earth is our only home in universe.If we don't protect it from now on,we will have nowhere to go when the environment being ruin.Look at what we have done to our matherland.
We let out too much exhaust gas that our atmosphere is no longer clear and health for breath.In many big cities,we can hardly see a bright blue sky.
We use as much resourse as we can find,then turn them into rubbish.These rubbish is taken up more and more space in our planet.
We also pollute water.Fishes and other beings are suffering to our mistakes.Some are died out,Some are dying out in future.
All of us must do something to protect our earth.Take a bus instead of private car;use goods that are made of recycle material.Many ways we can take in daily life should do good for our better future.
