Answer:
B. extraction
Explanation:
<u>In order to get oil for use, it needs to be extracted from under the ground.</u> Once the oil is located, the oil well is placed on the location. <u>The ground is drilled and the oil is popped out of the earth.</u>
While all the points in the oil handling process can be dangerous to the environment, <u>extraction has the biggest effect on the land and the sea as it can easily result in spills.</u> Oil spills affect many years later and are risky for the animals and plants. This way, the ecosystem is affected and the environment is hurt, impacting pollution and climate change.
