uh dear Learners welcome to the lecture on natural resources and sustainable development in this unit we will discuss natural resources classify them into types and explore how sustainable development utilizes these resources we all know that life on Earth is possible because it has all the essential resources needed for the life and grow growth of different life forms all these resources that exist in nature without any actions or intervention of human being are called natural resources air water and land are the three basic natural resources that all living systems use for their life and sustenance natural resources also include sunlight atmosphere all the Flora and Fauna microbial population and even the characteristics like the gravitational magnet itic electrical properties and forces and so on natural resources can be classified based on different criteria on the basis of renewability Natural Resources can mainly be classified into two different categories like renewable natural resources and non-renewable natural resources renewable natural resources are the resources that can be generated again once they are used up some of the examples of renewable natural resources include sunlight wind and wood on the other hand non-renewable natural resources are the one that exhaust after their frequent usage and sometimes it takes a really long time for them to regenerate the examples of these type includes natural gases coal and other fossil fuels based on the type of resources we can classify the natural resources into biotic water soil and mineral resources and energy resources in this video we will provide a brief description on different types of the resources first let's consider biotic resources biotic resources encompasses of all living organisms and organic materials found in the environment it includes the human being also examples of biotic resources include forest animals Birds fishes marine organisms as well as microbes and fungi in other words biotic resources encompasses all living systems in water water on land and in the air the second resource that we will discuss is water water is one of the most important component of the living system More than 70% of the cell is water if you consider the human body which has a water content of over 60% it is crucial for maintaining life from the cellular level to the organism level despite 75% of Earth's surface being covered with water the quality water suitable for human consumption is very l drinking water scarcity is a common problem that we all are facing in different parts of India as well as globally coming to the next resources that is the soil resources soil resources are regarded as the most significant part of the environment as it gives the physical base to Aid the cycling and productivity of biological resources it provides nutrition for the plants to grow inhabits many types of small animals and microbes storage of surface level water and most importantly it helps in the biogeochemical cycling it also provides all the minerals that are needed for the sustenance and development the next resource the energy resource is further divided into conventional and non-conventional energy resources conventional energy resources are otherwise called non-renewable energy resources like coal oil and natural gas Etc which cannot be renewed in a short per period of time on the other hand non-conventional energy like solar energy tidal energy and wind energy are renewable in nature understanding nature and its resources is very important for us especially in the current age as the population is on Rise but the resources are getting depleted wise use of resources and sustainability practices are the need of the hour I would like to conclude the session with a code by father of our nation Mahatma Gandhi the Earth has enough resources for our needs but not for our greed so let us know the resources use it for our needs avoid greed and protect our nature thank you [Music]
