Question
What is an ecosystem service? List any four important ecosystem services provided by the natural ecosystems. Are you in favour or against levying a charge on the service provided by the ecosystem?
✓

Answer

The product of ecosystem processes is called ecosystem service.
Following is the list of four important ecosystem services:
  1. Purification of air and water
  2. Rainfall
  3. Pollination of crops
  4. Assimilation of excess carbon
There should be no charge for ecosystem services because nature provides everything for free. However, there should be proper attempts to estimate the cost of these services. Data about costs of these services should be made available to the general public. Every person should be educated about the real value of ecosystem services. This will help us in appreciating the real value of services which we get from the ecosystem.
