Pollution and Human Impact Questions
Which human activity is a major contributor to the acidification of the oceans?
-
Renewable Energy Production
-
Sustainable Agriculture
-
Electric Vehicle Usage
-
Fossil Fuel Burning
D
Correct answer
Explanation
Fossil fuel burning, particularly the burning of coal and oil, releases large amounts of carbon dioxide into the atmosphere. Carbon dioxide dissolves in seawater, forming carbonic acid, which leads to the acidification of the oceans.
Which human activity is a major contributor to the pollution of the oceans?
-
Renewable Energy Production
-
Sustainable Agriculture
-
Electric Vehicle Usage
-
Industrial Waste Discharge
D
Correct answer
Explanation
Industrial waste discharge, particularly the discharge of untreated or poorly treated wastewater, is a major contributor to the pollution of the oceans. Industrial waste can contain harmful chemicals, heavy metals, and other pollutants that can contaminate marine ecosystems.

-
Industrial waste
-
Agricultural runoff
-
Sewage discharge
-
All of the above
D
Correct answer
Explanation
Water pollution can be caused by a variety of sources, including industrial waste, agricultural runoff, and sewage discharge.

Which of the following is an example of a market failure that can lead to environmental problems?
-
Positive externalities
-
Negative externalities
-
Perfect competition
-
Monopoly
B
Correct answer
Explanation
Negative externalities occur when the actions of one individual or entity impose costs on others without compensation. This can lead to environmental problems, such as pollution, when the costs of pollution are not reflected in the prices of goods and services.
