Cause

Why is this happen?

Resource depletion can be cause in many different ways. People are using these resources faster than they can be replenished. Basically the main causes to this problem are overpopulation and over consumption.

a. Overpopulation

There are a lot of people nowadays

Overpopulation is a situation where numbers of people are exceeding the current capacity of its habitat. This is because, as we can see nowadays there are increasing in birth, and also decline in mortality rates. Because of these reasons, there are a lot of demands in resources such as food, fresh water, and consumption of natural resources faster than the rate of regeneration. 

a. Over consumption 

The cause of the current economic crisis

Over-consumption is a situation where resource use has outpaced the sustainable capacity of the ecosystem. A prolonged pattern of over-consumption leads to inevitable environmental degradation and the eventual loss of resource bases. Generally the discussion of over-consumption parallels that of overpopulation; that is the more people, the more consumption of raw materials to sustain their lives.
