Answer: Ecosystem degradation
Definition of terminologies:
1. Natural ecological succession is the gradual change in the species composition and diversity in the ecosystem and the development of ecosystem over a period of time, resulting to stable community.
2. Ecosystem refers to group of plants, animals and other living components functioning in their non-living environment.
3. Ecosystem degradation refers to the depletion of resources in the ecosystem
Explanation:
When there is ecosystem degradation, it is necessary for environmentalists to get involved in creating man-made problems with natural ecological succession and this process is called ecological restoration.
Environmentalists creates man-made problems to either accelerate or reverse the change in the ecosystem.
Degradation comes in different ways (e.g increased soil erosion/flooding, disease outbreak,deforestation, pollution of the ecosystem etc.) and are greatly influenced by climate change.
Environmentalists curb the menace by:
1. Introducing resistant species against disease outbreak;
2. Improved ecosystem service;
3. Buffer zone establishment to resist pollution in any form.
