What are Professor Wycliffe's suggestions to help solve the problem of water pollution?
Answer
Professor Wycliffe makes various suggestions to help solve the problem of water pollution. These include: Keeping beaches clean from waste, such as cigarette ends and plastic bags which marine animals often mistake for food.
