KSEEB Solutions For Class 9 Social Science Economics Chapter 1 Natural Resources Points To Remember
Natural resources are naturally occurring substances that are considered valuable in their natural form. Natural Resources are generally classified as falling two types namely Renewable and non-renewable resources. The natural resources which get replenished as we use them are called renewable resources. Example: Water, land, forest, air, etc. The natural resources which get depleted as we go on using them are called Non-renewable resources. Examples: coal, petroleum, natural gas, etc.
- Resources can also be classified as biotic and abiotic resources.
- The resources which are derived from living organisms are biotic resources. Example: plants and animals.
- The resources which are derived from non-living components of nature are abiotic resources. Example: Water, soil, minerals
- The main factors of increasing scarcity are overpopulation, growing industrialization, expanding urban areas, atmospheric pollution, water pollution, and land degradation.
- Conservation of natural resources means not wasting them but using them judiciously so that there is a balance between nature and our use of natural resources.
- Conservation of resources can do it by adopting the 4R strategy. They are:
- Reduce,
- Reuse,
- Recharge and regenerate
- Research.
- The World Wildlife Fund has devised a measure called the ‘ecological footprint’ which gives an idea about the extent of consumption of resources and waste generation by a country or by an individual in a country.
- WWF defines a country’s ecological footprint as “ the sum of all the cropland, grazing land, forest and fishing grounds required to produce the food, fiber, and timber it consumes to absorb the wastes emitted when it uses energy and to provide space for infrastructure.
- Mahatma Gandhi stated that “ Be the change you want to see in others”
