So what could happen?
-Sea levels would also rise due to the melting of the glaciers and sea ice.

-Works using waves to trap air and pressurise it.
This then powers a turbine
-Environmentalists worry about noise pollution
from wave machines affecting plants and animals
-Could also disrupt shipping navigation.
-Wind can be used to
drive turbines which in turn produce electricity
-Some are on land, some on water where it's windier
megawatts of energy -
-Wind energy is renewable, clean, and cheap
-But critics say
