explain about environment source function?
Answers
The environmental source functions of the environment that support human life and economic activity. The first of these functions is the production of raw materials from the natural resources of soil, water, forests, minerals and marine life (the Earth’s ‘source’ function). The second is the safe absorption (through breakdown, recycling or storage) of the wastes and pollution produced by production and human life (the Earth’s ‘sink’ function). The third is the provision of the environmental or ecosystem services that support life without requiring human action, for example, climatic stability, biodiversity, ecosystem integrity and protection from ultraviolet radiation (the Earth’s ‘service’ function). The fourth is the intrinsic recreational, psychological, aesthetic and spiritual value of environments (the Earth’s ‘spiritual’ function).
The environment source function is known as the potential of an environment to provide service and materials.
- The main job of the environment is to give support human life and their economic activity.
- From the resources available naturally, producing the raw materials required is the first and main function performed in the environment source function.
- The next and second function is that it can absorb the waste and the pollution produced.
- But the source function will reduce as its resources are consumed or pollution contaminated the resources.
