NATURAL RESOURCE
is a source of products that are inherent to earth surface.
Natural Sources includes:
1. Renewable resources.
2. Non- renewable resources.
Natural Resources are exploited to create the products.
Natural resources extraction causes great environmental disruption.
2
Chief Natural Resources
• Forests Resources
• Water Resources
• Land Resources
• Mineral Resources
• Energy Resources
3
Forest Resources
• Biotic community
• Renewable natural resource
Benefits of Forests
• Protective Function
• Productive Function
• Regulative Function
• Accessory Function
4
http://www.forestworldme.com
Large scale of destruction of forests leads to a number of adverse
environmental effects.
• Loss of natural habitat of wild animals and plants
• Increased intensity and frequency of natural disasters
• Land Degradation
• Loss of forest products
• Change in climatic conditions
• Loss of revenue
5
Water Resources
Potentially source of water supply.
Effects of Over Utilization of Ground water
• Sharp decline in water table.
• Loss of vegetation and wildlife habitat.

Mineral Resources
• Minerals are naturally occurring chemical compounds, which are formed
under the crust of the earth.
• Minerals are non-renewable resources
7

Types of Minerals
• Metallic Minerals (nickel, copper, zinc, lead and gold)
• Non-metallic minerals (Carbon, gypsum, precious stones, sulphur, diamond)
• Fuel Minerals
1.Coal
2.Petroleum
3.Natural Gas
8

Environmental Effect of Extraction
• Destruction of forest
• Soil erosion and reduces soil fertility.
• Generation of large amount of wastes
• Pollution of air, water and land.
• Occupational health hazards
9
Energy Resources
• All living creatures on the earth, either it is a plant, an animal or a microbe
need energy to perform their vital functions.
• The earth is a storehouse of energy.
