Factors such as over harvesting, habitat destruction, climate change, and pollution, can lead to exceeding the sustainable yield. This results in resource depletion, ecosystem collapse, economic losses, and long-term environmental damage.</p> Signup and view all the answers

Study Notes

Nature's Provisions

  • Natural gifts including water, air, soil, minerals, plants, and animals fulfill daily needs.

Resources Defined

  • Environmental materials satisfy human requirements; early humans learned to convert these into useful things to satisfy their needs.
  • Wind can be harnessed via windmills to produce electricity.
  • Wind became a resource upon discovering electricity generation from it through windmills.
  • All materials available in the environment which satisfy human needs are resources.

Types of Resources

  • Natural resources: Readily available in the natural world; land, air, water, soil, minerals, forests, and animals are examples.

Types of Natural Resources

  • Renewable resources
  • Non-renewable resources

Renewable Resources

  • Inexhaustible resources are capable of renewal.
  • Examples include air, water, soil, plants, and solar energy.

Air

  • Essential for all living things.
  • Wind is used to drive wind turbines to generate electricity in wind farms.
  • Muppandal Wind Farm in Tamil Nadu is India's largest.

Water

  • Required for drinking, washing, cooking, growing crops, and generating hydroelectricity for many other purposes.
  • Hydroelectricity is produced from the energy of water falling from a high dam.
  • Water falling from a dam generates hydroelectricity.
  • As a critical natural resource, it must be conserved.

Soil

  • Critical for plant growth; fertile soil results in more bountiful crops.
  • Soil types in India include alluvial, black, red, laterite, mountain, and desert soils.

Plants

  • A source of food and oxygen, essential for sustaining life.
  • Plants provide nourishment for animals.
  • Plants prevent soil erosion, give habitat for animals, and are considered 'green gold'.
  • The vast majority of animals rely on plants for nutrition.

Animals

  • Serve as suppliers of food such as milk, eggs, meat, and oil.
  • Animal hair makes woollen clothes.
  • Animal waste can be employed as fertilizer.
  • Fish waste and bird droppings are also viable as fertilizers.

Solar Energy

  • Energy is derived from the sun.
  • Plants utilize it in the process of food production.
  • It can be used for street lighting, cooking, water heating, and generating electricity.

Non-Renewable Resources

  • Exist in finite quantities and cannot be regenerated once depleted.
  • They are exhaustible resources.
  • Examples include fuels (coal, petroleum, natural gas) and metals (iron, copper, aluminium ).

Coal

  • Employed for cooking, heating, generating electricity, and powering steam engines and factories.
  • A vital power source, despite substantial reserves, it is a limited resource.

Petroleum

  • Colloquially referred to as black gold.
  • Refined into petrol and diesel, used as fuel in various vehicles.
  • Reserves are limited and not available in all countries.

Natural Gas

  • Commonly found alongside petroleum in oilfields and used as compressed natural gas (CNG) to power vehicles.
  • Functions as another form of fuel.

Minerals

  • Natural substances constituting all rocks.
  • Ore is defined as a rock containing a significant amount of a specific mineral.
  • Ores are extracted from beneath the Earth's surface.
  • Minerals occur in two categories: metallic and non-metallic.

Metallic Minerals

  • Minerals from which different metals are derived; for instance, iron, copper, manganese, bauxite, and gold.
  • Ores undergo melting processes in factories to yield pure metals.

Non-Metallic Minerals

  • Minerals that do not yield metals such as limestone, precious stones, salt, coal, and petroleum.
  • Coal and petroleum are also termed as mineral fuels or fossil fuels.
  • These substances are used as fuel.

Conservation

  • Entails the careful utilization of natural resources to ensure longevity.
  • Depleting groundwater reserves can precipitate water scarcity.
  • To maintain groundwater reserves, water extraction rates must not exceed the rate of natural replenishment from rain.

Ways to Conserve Natural Resources

  • Reducing pollution of air, water, and soil is necessary.
  • Plant more trees.
  • Refrain from hunting animals.
  • Save electricity.
  • Promote development of alternative energy sources.
