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.
