Stop cutting down trees. Stop burning fossil fuels. Stop using plastic. But why? Because when we do these things, it is harmful to nature.
CLIMATE CHANGE IS BAD!
When we throw away plastic, a lot of it is washed into the sea, where it can be very harmful to life there. But there is another reason that fish are becoming endangered. Too many fish are being caught and not all of them are used/eaten. This is known as overfishing.
