Answer:
causes the depletion of our natural resources
Overpopulation.
With 7 billion people on the planet, the demand on Earth’s resources continue to increase.
Over consumption and waste.
This is the excessive and unnecessary use of resources.
Deforestation and the Destruction of Ecosystems leading to loss of biodiversity.
Mining of Minerals and Oil.
Technological and Industrial Development.
Erosion.
Pollution and Contamination of resources.
resources are in decline :
Water –
Even though you see water everywhere and our planet is 70% water, only 2.5% of that 70% is fresh water.
The rest is salt water and not useful to humans at all.
That small percentage of fresh water is mostly in the form of ice or permanent snow cover.
So, we really have only a few percent available for use.
The Food and Agriculture Organization of the United Nations predict that by 2025, 1.8 billion people will have no water to drink.
Coal –
This is the most used fossil fuel and a non-renewable energy source.
Peak coal extraction is predicted between 2025 and 2048.
In 2011, it was estimated that we have enough coal to meet global demands for 188 years.
If the demand increases, the timeframe will decrease.
Oil –
Without oil, global transportation will be severely debilitated.
The BP Statistical Review of World Energy estimates that there is 188.8 million tons of oil left in the known oil reserves as of 2010.
If our current demand continues, this oil will only be enough to supply the world demands for the next 46.2 years.
Natural Gas –
As of 2010, the known reserves of natural gas was estimated to last 58.6 years with the current global production.
Fish –
Fishermen from a lot of coastal provinces report a decline in their catch.
Other marine species such as the tuna is close to extinction due to overfishing.
This is a resource since Fish is part of our major food group.
