Question

Discuss the long term implications of increased demand for environmental resources exceeding their natural regenerative capacity.

Hint:

Say that demand has gone past the regenerative capacity. Then state the three results: depletion of resources, more waste and pollution, and a serious environmental crisis.

Answer 1

Step 1: Understand the key terms:
Regenerative capacity is the rate at which nature renews its resources, such as forests, fish stocks and fresh water.
Absorptive capacity is the ability of the environment to take in waste and pollution without getting damaged.
The question asks what happens in the long run when we use resources faster than nature can renew them.

Step 2: Why demand has crossed the limit:
Rapid population growth and industrialisation have raised the demand for resources for both production and consumption.
When this demand becomes larger than the natural rate of regeneration, the stock of resources starts falling.
At the same time, more production and consumption means more waste, so the absorptive capacity of the environment is put under heavy pressure.

Step 3: Implication 1: Resource depletion:
Renewable resources like forests and groundwater get used up faster than they grow back. Non-renewable resources such as coal and petroleum are lost for good.
Future generations are left with fewer resources, so the economy cannot keep its growth going for long.

Step 4: Implication 2: Pollution and waste:
Waste generation rises and pollution of air, water and land becomes serious. The environment can no longer clean itself.
This hurts health, lowers farm output and raises the cost of treating the damage.

Step 5: Implication 3: Environmental crisis:
Loss of forests and species, global warming and ozone depletion become more severe. Together they form a serious environmental crisis.
Development that ignores this limit cannot be sustained, which is why sustainable development is needed.

Final Answer:
Demand beyond the regenerative capacity depletes resources, overloads the absorptive capacity, increases waste and pollution, and leads to a serious environmental crisis that threatens future development.
