name 5 threats facing wilderness and fragile environments and explain 3
TOURISM
(releases co2, greenhouse gas, global warming, melting ice caps)
OIL DRILLING
( global warming, co2, greenhouse effect, Svalbard has glaciers OR pollution of environment, reduces biodiversity, risk of extinction)
COAL MINING
( employs 300 people
GREATER DEVELOPMENT OF COLD ENVIRONMENTS
( more roads and electricity pylons, damaging fragile environments)
