Harvesting, Mining and Drilling

How we obtain our Resources


Harvesting involves collecting material that is
above ground or close to the surface.
Peat and wood are harvested materials.

Peat is made from decayed plant matter. It is
burned for energy and forms in bogs and
wetlands. Peat is not as widely used as it used
to be.

Mining involves digging deep into the ground.
Resources that we mine include rocks, minerals
and coal.



Shaft is dug parallel to deposit
Explosives are used to loosen the deposit
Dangers:




Mine collapse
Explosion of natural gas stores
Lung disease from mine air pollutants
More expensive, but less environmental damage
compared to surface mining

Drilling involves putting a well thousands of
feet into the ground to reach natural gas or oil.
