The correct answer is: C. acid rain.
When oil and gas resources are burnt, they release harmful pollutants into the atmosphere. These pollutants can travel long distances and can be deposited in forests and lakes. When these pollutants react with water, they can form acid rain. Acid rain can damage trees and other plants, and can also make lakes and streams acidic, which can kill fish and other aquatic life.
Deforestation is the clearing of forests for other uses, such as agriculture or development. Water pollution is the contamination of water bodies with harmful substances, such as sewage, industrial waste, or agricultural runoff. Forest fires are caused by a variety of factors, including lightning strikes, human activity, and climate change.
Acid rain is a major environmental problem that can have a significant impact on forests and lakes. It can damage trees and other plants, and can also make lakes and streams acidic, which can kill fish and other aquatic life.
