Distinguished between degradation and conservation

Degradation: The process by which the productivity, usefulness and the bio diversity of the soil is lost due to deforestation, poor agricultural practises, land pollution and other human generated problems is degradation.​
The degradation of the wastes or other substances by the help of living organisms like bacteria is called biodegradation.    
Degradation also refers to the breakdown of the complex substances into respective constituents by external forces. 
Conservation: Conservation is the protection, preservation, management, or restoration of wildlife and natural resources such as forests and water in an area so that the abundance and distribution of species and communities provide for continued existence and normal ecological functioning, including adaptation and extinction. 
In-situ conservation - In order to conserve biodiversity better, some of the world’s biodiversity hotspots (with high degree of biodiversity and endemism) have been identified and are protected. In India, biosphere reserves, wildlife sanctuaries, and national parks are built for this purpose.
Ex-situ conservation - The threatened species of plants and animals are taken out of their habitats and are kept in special settings as in zoological parks, botanical gardens, and wildlife parks.
