Unit 12

More pollution in the oceans

    Worldwide ocean pollution is getting worse, say scientists. While some pollution like dust from volcanoes is natural, most is man-made. Oil, garbage and chemicals from human activities are putting sea life in danger. When the water is very dirty, there is not enough oxygen for fish and plants to breathe.

              Experts say that our everyday actions make a big difference to the ocean. For example, anything that we put down the drain could end up in the sea. We shouldn’t put anything except water down there. It’s also important to take care of the beaches, and always take garbage home with us.

The text is about going to the beach.
