acknowlegements to:

Land Pollution, besides being an eyesore to people, can be unhygienic and even dangerous to human beings. Waste attracts pests such as flies and rats which carry germs and spread diseases. In addition, farmers who are exposed to large amounts of pesticides risk developing cancer and liver failure.

How about all the animals? They are negatively affected by the actions of humans too. When pesticides are used on farms, besides affecting pests, the chemicals also affect useful organisms such as earthworms, which help to fertilise the soil. When the earthworms are eaten by birds, the toxic chemicals from the pesticides stored in their bodies are passed on to the birds . This may affect their reproductive systems. The birds may lay eggs with thin shells that are fragile and break easily, killing the nestling inside. Eventually, this could lead to the extinction of some species of birds.
