What are the implications of unsustainable use / over exploitation of natural resources?
Unsustainable use and overexploitation of natural resources have severe consequences. When renewable resources are harvested faster than Nature can restore and regenerate them, they become depleted.
For example, overexploitation of groundwater in Punjab has led to water levels dropping to depths of about 30 metres, with 80% of the area classified as 'over-exploited'.
Scientists have warned that irresponsible treatment of natural resources leads to pollution, biodiversity loss, and climate change.
Industrial waste discharged into rivers disturbs Nature's cycles of restoration and regeneration, making water bodies poisonous and unable to support life.
In Punjab, chemicals from pesticides and fertilisers have dissolved in groundwater, causing health hazards.
Overexploitation can turn renewable resources into non-renewable ones, threatening the needs of future generations and causing long-term consequences that take time and effort to heal.
Explanation
The chapter extensively covers implications of overexploitation on pages 6-7, 12-14, and 18. The Punjab caselet (pages 13-14) provides a concrete example of how overexploitation of groundwater led to a crisis. The chapter emphasises that irresponsible treatment leads to pollution, biodiversity loss, and climate change, and that short-term gains can create long-term sustainability problems.
Solution Steps
Renewable resources become depleted when harvested faster than Nature can restore them.
Overexploitation of groundwater in Punjab has caused water levels to drop significantly.
Irresponsible treatment of natural resources leads to pollution, biodiversity loss, and climate change.
Industrial waste discharged into rivers disrupts restoration cycles and poisons water bodies.
Chemicals from pesticides and fertilisers dissolve in groundwater, creating health hazards.
Overexploitation threatens future generations by turning renewable resources into non-renewable ones.
