Environment is defined as the total planetary inheritance and the totality of all resources. It Involves:- (1) Biotic Factors (2) Abiotic Factors

Biotic factors Birds Animals Plants Forest

Abiotic factors Air Water Land

Non-renewable Resources The main function of the environment is that it supplies resources to us. Resources Renewable Resources Non-renewable Resources

Renewable Resources Renewable resources are those which can be used without the possibility of the resource becoming depleted or exhausted. Trees in Forest Fishes in the Sea

Non-renewable Resources Resources, on the other hand, are those which get exhausted with extraction and use. Fossil fuel

Problem of Environmental Crisis arises. Resources Environment Users- Human Beings Environment supplies us the useful resources as per our needs and regenerate them continuously. But if, Resource Extraction > Rate of Generation Problem of Environmental Crisis arises.

Causes of Environmental Crisis The Rising Population of the Developing countries. The Affluent Consumption. Increasing Production Standards. The Greenhouse Effect.

Cost of Environmental Crisis Huge amounts on technology and research to explore new resources. Health costs of degraded environmental quality Increased Financial Commitments Decline in air and water quality Medical cost against health diseases

It is clear that the opportunity costs of negative environmental impacts are high. Hence, the environmental issues of waste generation and pollution have become critical today.
