Introduction:
Nature is full of resources. Living beings use these resources for different purposes. The thing that makes them useful is their worth. If any of these resources get exhausted, it can affect the lives of human beings and other creatures. Therefore, it becomes important for everyone to learn about the significance of resources. In this chapter we will know the meaning, types and measures for conservation of resources.
Meaning of Resources:
Anything that can be used to satisfy a need is a resource.
It is not necessary that all resources will have economic value It means, some resources have economic value; for example: metals. And some resources such as grandma’s home remedy, your paintings etc. may not have economic value.
