Answers
Answer:
Do Not Litter near a water body such as a lake, river or sea.
Plant trees in catchment areas of rivers and also on banks.
Trees not only check soil erosion but also retain soil moisture and feed rivers to keep them flowing.
Do not block/ stop natural drains by constructing on drains or dumping wastes.
Plant flora at Lakes or Rivers. If you live in an area where a lake or river is present, you might want to think about planting some local plants near the water. Trees are also helpful. Not only do they look beautiful when they grow, but they also help in protecting the water body from pollutants. Vegetation also limits the carbon dioxide in the water, which balances out its pH level.
Stop Chemical Pollution. If you notice someone throwing chemicals into the river or lake, or hear about such an incident inform your local authorities about the matter. Give them a feed back insisting on a speedy action. Your silence may aggravate on the situation
