Explain the concepts of preservation and conservation
What will be an ideal response?
Answer: Preservation and conservation are two different ways to perceive and manage resources. Preservation is the maintenance of resources in their present condition, with as little human impact as possible. Preservation takes the view that the value of nature does not derive from human needs and interests, but from the fact that every plant and animal living on Earth has a right to exist and should be preserved regardless of the cost. It does not regard nature as a resource for human use.
In contrast, conservation is compatible with development but only if natural resources are utilized in a careful rather than a wasteful manner. Conservation is the use and management of natural resources such as wildlife, water, air, and Earth's resources to meet human needs, including food, medicine, and recreation.
Renewable resources such as trees are conserved if they are consumed at a rate less than or equal to the rate at which they can be replaced. Nonrenewable resources such as fossil fuels are conserved if they are used as efficiently as possible, allowing time to develop alternative energy resources for the future.
