Is drilling for oil necessary?
Oil drilling reduces the pressure of oil reservoirs underground, which greatly reduces the amount of hydrocarbon seepage – and the amount of methane gas in the atmosphere. Scientists theorize that increased drilling operations could continue to benefit aquatic and atmospheric conditions.
Why should we not drill for oil in the Arctic?
Expansion of oil and gas drilling in their habitat could be extremely damaging. Direct contact with spilled oil would kill polar bears but an invisible threat could persist for years, as toxic substances lingering in ice or water may impact the entire food web of the Arctic ecosystem for years to come.
Why is oil drilling in Alaska bad?
Oil development would bring roads, airstrips, heavy machinery, noise and pollution. This would damage the refuge’s fragile tundra ecosystem and disrupt age-old migration and denning patterns for caribou, polar bears and other animals.
What happens while drilling for oil?
The drilling process is, not surprisingly, unlike using a power drill on a piece of wood. The most prominent difference is that the he hole is filled with “mud” — a mixture of fluids, solids and, chemicals — that lubricate the bit and help move the broken rock out of the way.
What are bad things about oil?
Spilt oil can pollute streams, rivers and, if it soaks through the soil and rock, groundwater. In the UK our drinking water supplies come from rivers and groundwater. We must protect them both from pollution. Oil is toxic and harmful to plants and animals and a threat to their habitats.
Does Antarctica have oil?
There are known reserves of oil and coal as well as mineral deposits in Antarctica, although detailed knowledge of these mineral deposits is sketchy. In the last 50 years of scientific research, no large deposits of mineralized rocks have been found.
How does oil drilling affect wildlife?
Oil destroys the insulating ability of fur-bearing mammals, such as sea otters, and the water repellency of a bird’s feathers, thus exposing these creatures to the harsh elements. … Many birds and animals also ingest oil when they try to clean themselves, which can poison them.
Can oil drilling cause earthquakes?
The dense, salty water produced as a byproduct of oil and gas operations can stress fault lines even when operations cease, new research shows. Injected back into the ground, wastewater can lead to stronger earthquakes. …
