- Radioactive pollution: It is the most dangerous of all the forms of environmental pollution. The effects caused by radioactive pollution are not temporary and almost irreparable. The major effects of radioactive pollution are:
- Different birth diseases
To meet the needs of the overgrowing population and technological advancements, the demand for natural resources keep on increasing. But we cannot ignore the fact that the environment is paying a huge amount to meet all these needs and in return affecting the living creatures life.
If environmental pollution increases at the same pace, it will make it difficult for future generation to survive. So it is highly recommended to adopt effective measures to reduce the causes of environmental pollution.
