The document discusses the concept of the natural environment, which includes all living and non-living things on Earth that are not human-made, and categorizes natural resources into renewable, non-renewable, exhaustible, and non-exhaustible types. It explains the importance of the environment for air purification, water sources, and economic activities, while highlighting practices for resource conservation across various domains such as soil, water, air, and wildlife. The text emphasizes the necessity of sustainable resource management to protect these vital natural components.
GREEN SKILL[PART-2]
- 1. GREEN SKILLS CLASS: IX INFORMATION TECHNOLOGY-402 PART-2
- 2. NATURAL ENVIRONMENT The term 'natural environment' refers to the non-human-made surroundings and conditions in which all living and non-living things exist on Earth. A natural environment is one in which human impact is kept under a certain limited level. Everything that is not human-made comes under natural environment. Land, air, water, plants and animals all comprise the natural environment.
- 3. Resources are categorized into many categories: Natural Resources Renewable/Non-renewable Resources Exhaustible / non- exhaustible Resources Let us understand these types one by one:
- 4. Natural Resources: Natural resources can be defined as the resources that exist (on the planet) independent of human actions. Common examples of natural resources include air, sunlight, water, soil, stone, plants, animals, and fossil fuels. Natural resources are Earth materials used to support life and meet the needs of people. Any organic material used by humans can be considered as a natural resource. Natural resources include oil, coal, natural gas, metals, stone, and sand. Air, sunlight, soil, and water are other natural resources.
- 5. Renewable/Non-renewable Resources Renewable resources: Non-renewable Resources: Renewable resources are the ones that are consistently available regardless of their use. Examples include vegetation, water, and air. A renewable resource is one that can be used repeatedly and does not run out because it is naturally replaced. A renewable resource, essentially, has an endless supply such as solar energy, wind energy etc.
- 6. Renewable/Non-renewable Resources Non-renewable resources: Non-renewable Resources: Non-renewable resources are the ones that cannot simply be substituted or recovered once they have been utilized or destroyed. A non-renewable resource refers to a natural resource that is found beneath the earth, which when consumed, does not replenish or renew at the same speed at which it is used up.
- 7. Exhaustible / non- exhaustible Resources Non-Exhaustible resources: The natural resources that the living being of the earth can never consume to finish them is known as Non-exhaustible resources. Nature has blessed us with an unlimited supply of resources such as air, water and sunlight. These resources are called Non- exhaustible resources.
- 8. Exhaustible / non- exhaustible Resources Exhaustible resources: Resources which are available in limited quantity and can be completely used up by human activities like : coal and petroleum.
- 9. How Environment is Crucial for Us The environment is responsible for air purification and disaster control. The environment is the source of clean water, medicines, clothing, biofuels, wood and fossil fuels. the environment supports most economic activities in the world. Economic activities, such as fishing, agriculture, manufacturing and tourism, depend largely on the environment. The environment provides natural beauty for the amusement and relaxation of human beings.
- 10. Practices for Conservation of Resources Soil: Afforestation Plantation of bushy plants and trees in deserts Crop rotation Controlling overgrazing Controlling the shifting cultivation
- 11. Practices for Conservation of Resources Water: Drip irrigation Recycling of waste water Rain water harvesting Treatment of sewage water Treatment of industrial waste before discharge water into drains and rivers
- 12. Practices for Conservation of Resources Air: Car pooling Increasing height of chimneys Use of CNG Public awareness Use of electric automobiles
- 13. Practices for Conservation of Resources Forest and Wildlife: Prevention of forest fire Establishment of national parks, wildlife sanctuaries, zoological gardens
- 14. Practices for Conservation of Resources Minerals: Reuse and recycling Use of modern, efficient technology Changing energy-waste and lifestyles Using energy-efficient equipment Use of LPG(liquid petroleum gas) in rural areas. Use of CNG(Compressed natural gas) in vehicles.
