Fossil Fuel Extraction
Fossil fuels (coal,
oil, and natural gas) are a non-renewable, finite source
of energy, formed from the remains of ancient plants and
animals that lived up to 300 million years ago. These fuels
power cars, mass transit systems, and electrical grids,
plus provide the raw material for plastics and other consumer
items. Most of the world’s energy demands are met
by the combustion of fossil fuels.
To release their stored
energy, fossil fuels must be burned. During this combustion
process, a variety of emissions and particulates, including
ash, sulfur, nitrogen, and carbon, are released into the
atmosphere. These emissions pose a human health risk, and
harm the environment by combining with water vapor in the
air to form acid rain. Burning fossil fuels also releases
carbon dioxide, a greenhouse gas that scientists have shown
to be the key factor behind global climate change.
Birds are impacted by fossil
fuel extraction and use in a wide variety of ways. Climate
change is one of today’s greatest threats to bird
habitats, migration patterns, and nesting success. Oil extraction
facilities and storage pits also pose a serious threat to
birds, destroying and degrading suitable habitat, and often
directly causing significant mortality through spills, poisoning,
collisions, and destruction of food sources. Mining destroys
forest and other habitat to reach underground deposits and
is also a major threat to birds. The most harmful form of
coal mining is mountaintop removal/valley fill, whereby
entire mountaintops are removed and dumped in surrounding
valleys, destroying thousands of acres of forest and stream
habitat.
