These days, environmental problems are becoming more and more serious.

One possible version:
Protecting Our Natural Home
These days, environmental problems are becoming more and more serious. We can often see rubbish in our school. Water and electricity are often wasted in our daily lives. It’s our duty to protect our natural home.
We can take simple but useful actions. First, we should throw rubbish into bins and stop using disposable chopsticks and boxes. Second, remember to turn off lights and taps when we don’t need them to save energy.
Let’s start with small things around us. If everyone makes an effort, our natural home will become better and more beautiful.
