impacts of exploiting minerals & conservation :
TRANSCRIPT
#1.
• The most environmentally friendly
way is to fill in the hole and replace
the top soil, in order to leave the land
in similar way what it was like before
the work began.
But…
• This only happens when the mine
is small…and…
• When the mining company is
forced to abide by strict rules.
#2.• Old quarries and large holes left after
mining stopped are often convenient
places for the disposal of waste.
• For e.g:
–Landfilling : which is a cheap and easy
way to dispose of waste
• The amount of waste to be disposed in
developed countries can be enormous.
• The waste is tipped into the hole; from
time to time it is leveled off and
compacted.
• When full, the land can be reclaimed for
other uses, as:
– Forestry, farming or recreation.
• Disposal of waste in landfill sites needs
to be managed, otherwise, it contaminates
the land and become a hazard to the
health of people living and the workers in
surrounding area.
