TASK 3: Read the text, then say true or false:
Our oceans are becoming extremely polluted. Most of this pollution comes from the land, which means it comes from
people. Firstly, there is raw sewage, which is pumped directly into the sea. Many countries, both developed and
developing, are guilty of doing this. Secondly, ships drop about 6 million tons of garbage into the sea each year. Thirdly,
there are oil spills from ships. A ship has an accident and oil leaks from the vessel. This not only pollutes the water, but
also kills marine life. Next, there are waste materials from factories. Without proper regulations, factory owners let the
waste run directly into the rivers, which then lead to the sea. And finally, oil is washed from the land. This can be the
result of carelessness or a deliberate dumping of waste.
