The concept of Sustainable Development was derived in 1987, from the United Nations World Commission on the Environment and Development Report, Our Common Future, commonly called the Brundtland Report.
Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.

Importance of Sustainable Development
These are the benefits of Sustainable Development:
1) Sustain Biodiversity - In nature ecosystem plays an important role where all species depends on each other. However, they are small like insect or extremely big in like whale, in size, but they all have equal importance in life cycle, so sustainable development can save many species from being extinct.
3) Abundance of Resources - Sustainable Development emphasis on using natural resources intelligently, so that present generation could meet their demands without forgetting future generation . The future generation get health future and abundance of resources.
5) Reduce Wastage - Sustainable Development teaches us we should use minimum natural resources like petrol, wood, water. This will reduce extra pressure on our natural resources. so that it can be preserved for next generation.

| Natural Resources |
1) Renewable Resources
The Natural Resources available in abundance, which doesn't end, called renewable resources. For example water, Sun and wind. Natural Resources can be utilize for generating electricity, which don't emit poisonous gas in nature. Renewable resources are also good for sustainable development.
i) Solar Energy - The sun has been the main sources of energy and it is being used to generate electricity using solar panel and warm up water using solar water heater. In Madhya Paradesh, India has set up Asia's biggest solar power plant.
ii) Wind Energy - Wind Energy is also used to convert mechanical energy into electrical energy and to run windmills, so it reduces the use of coal and fossil fuel to produce power. It promotes sustainable development.
iii) Water Energy - In Dam, water is stored to run turbines. Turbines convert mechanical energy into electrical energy, which is used for domestic and commercial purposes. Rain water can be stored in tanks for irrigation and domestic use.

2) Non-Renewable Resources
Natural Resources wood, coal, petrol which are limited in nature, called Non-Renewable Resources. Non-Renewable Resources also emit harmful gases in nature which is the main cause of global warming, so we should switch to renewable natural resources.
i) Petrol - Petrol is used for transportation which emit harmful gases and the main cause of air pollution and global warming.
ii) Coal - Coal is also used for generation electricity. In India 75% electricity is generated by using coal which emit large amount of pollution in nature.
iii) Wood - Wood is used for fire in home and in factories which also produced harmful gases. Indian government has taken initiative providing LPG to each home.

Biodegradable and Non-Biodegradable substance
1) Biodegradable Substance: A substance which react with water and soil and degrade in environment after sometime is called Biodegradable Substance.
For example: Plant, Dead Animals, Paper etc
2) Non - Biodegradable Substance: A substance which does not reach with water and soil and does not degrade in environment is called Non - Biodegradable Substance.
