2. Coal And Petroleum Conservation
3. Big Dams- Advantages and Disadvantages
4. Water Harvesting
5. Sustainability Of Natural Resource

Answer 1

Answer:

Natural resources are resources that occur in nature without any manmade assistance. Any naturally occurring substance qualifies as a natural resource, including animals, plants, water, oil, coal, minerals, timber, land, light, soil, and energy. Natural resources can be renewable or nonrenewable:

Renewable resources refer to undiminishable substances, such as solar and wind energy, biomass energy, and hydropower.

Nonrenewable resources refer to resources that cannot be naturally replenished at an adequate pace to meet growing demands. Nonrenewable resources include water, fossil fuels, natural gases, minerals, and nuclear energy.

1. Conservation and Judicious Use Of Natural Resources:

Natural resources are conserved for their biological, economic and recreational values.

• The use of natural resources in excess and unplanned way leads to imbalance in the environment. Natural resources are conserved for their biological, economic and recreational values.

• judicious use of resource means to use natural resources like water, wisely without wasting it.

• Following are some of the ways and methods which help in the judicious use of resources :

1. Resource planning and resource management.
2. Maximize efficiency and minimize wastes.
3. Reuse and recycle.
4. Plant trees and conserve water.
5. Use more and more renewable resources.
6. Use alternative raw material or resources.

2. Coal And Petroleum Conservation:

Coal and petroleum which are also called fossil fuels or non- renewable energy resources. One way of fuel conservation is to avoid their wastage.

Switching to alternative sources such as solar energy in the forms of solar heater, solar cookers, use of natural gas and wind energy are some ways to reduce their usage.

3. Big Dams- Advantages and Disadvantages:

Benefits Of Large Dams

1. WATER FOR DRINKING AND INDUSTRIAL USE.
2. IRRIGATION.
3. FLOOD CONTROL.
4. HYDRO POWER GENERATION.
5. INLAND NAVIGATION.

Disadvantages of Dams:

1. Displacement of people during construction.
2. Reservoirs often emit a high percentage of greenhouse gases.
3. Often disrupts local ecosystems.
4. It disrupts the groundwater table.

4. Water Harvesting:

The term 'water harvesting' generally refers to the collection of rainstorm-generated runoff from a particular area (a catchment) in order to provide water for human, animal, or crop use.

5. Sustainability Of Natural Resource:

Sustainability is the practice of using natural resources responsibly, so they can support both present and future generations.

• Forests are one natural resource that sustainability groups are focused on conserving. Forests made up about 30 percent of Earth's land mass in 2015, but that number is at risk of decreasing.
