Questions

Which 1987 international agreement successfully phased out CFCs to protect the ozone layer?
1. Kyoto Protocol
2. Paris Agreement
3. Montreal Protocol
4. Rio Declaration
Show answer
Answer: Montreal Protocol
The 1987 Montreal Protocol phased out chlorofluorocarbons (CFCs) used in refrigerants and aerosols that were destroying the stratospheric ozone layer. It is widely considered the most successful international environmental agreement — the ozone layer is now slowly recovering, and the protocol is credited with preventing millions of skin cancer cases.
The U.S. Clean Air Act requires the EPA to set standards for outdoor air pollutants that harm public health.
Show answer
Answer: True
The Clean Air Act (1970, strengthened 1990) authorizes the EPA to set National Ambient Air Quality Standards (NAAQS) for six principal pollutants including ozone, particulate matter, and carbon monoxide. It has dramatically improved U.S. air quality and is estimated to prevent hundreds of thousands of premature deaths annually.
The ___ principle holds that when there is scientific uncertainty about an environmental risk, precautionary action should be taken rather than waiting for full proof of harm.
Show answer
Answer: precautionary
The precautionary principle holds that when an action or policy raises threats of harm to health or the environment, precautionary action should be taken even if some cause-and-effect relationships are not fully established scientifically. It was formalized in the 1992 Rio Declaration on Environment and Development.
Which of these BEST describes the 'tragedy of the commons'?
1. Government failure to fund public parks
2. Overuse of shared resources when individuals act in self-interest, degrading them for all
3. The difficulty of passing environmental legislation in Congress
4. When poor countries cannot afford clean technology
Show answer
Answer: Overuse of shared resources when individuals act in self-interest, degrading them for all
The 'tragedy of the commons,' coined by Garrett Hardin (1968), describes how shared resources — fisheries, clean air, groundwater — tend to be overused because each individual benefits from overuse while the costs are shared by all. It's used to explain overfishing, air pollution, and other collective action problems.
A renewable portfolio standard (RPS) requires:
1. All cars to run on renewable fuel
2. Utilities to generate a certain percentage of their electricity from renewable sources
3. Homeowners to install solar panels
4. Banning natural gas pipelines
Show answer
Answer: Utilities to generate a certain percentage of their electricity from renewable sources
A Renewable Portfolio Standard (RPS) — also called a Renewable Energy Standard — requires electricity providers to meet a minimum percentage of their supply from renewable sources like wind and solar. Over 30 U.S. states have RPS policies, and they've been effective drivers of clean energy growth.
The Kyoto Protocol required developing nations like China and India to make binding emission cuts.
Show answer
Answer: False
The Kyoto Protocol (1997) required only developed (Annex I) nations to make binding emission reduction commitments. China, India, and other developing nations were exempt, which led the U.S. Senate to refuse ratification and was a central weakness of the agreement. The Paris Agreement (2015) applied to all nations.
Methane is a potent ___ gas, and is emitted by livestock, landfills, and natural gas systems.
Show answer
Answer: greenhouse
Methane (CH4) is a potent greenhouse gas — over 80 times more powerful than CO2 over a 20-year period at trapping heat. Major sources include livestock digestion, rice paddies, landfills, and natural gas leaks. Reducing methane emissions is considered one of the fastest ways to slow near-term warming.
Which policy tool imposes a fee directly on each ton of carbon dioxide emitted?
1. Cap-and-trade
2. Carbon tax
3. Renewable subsidy
4. Emission offset
Show answer
Answer: Carbon tax
A carbon tax directly puts a price on each ton of CO2 emitted, making fossil fuels more expensive relative to clean alternatives. Cap-and-trade also prices carbon but does so indirectly through permit markets. Both are 'carbon pricing' mechanisms. British Columbia's carbon tax is considered one of the most successful in reducing emissions.
Environmental justice advocates argue that pollution burdens fall equally across all income groups and races.
Show answer
Answer: False
Environmental justice research consistently shows that pollution burdens are NOT distributed equally. Low-income communities and communities of color are significantly more likely to live near highways, industrial facilities, power plants, and toxic waste sites — and to suffer worse health outcomes from pollution as a result.
The concept of 'sustainable development' means:
1. Halting all economic development to protect nature
2. Meeting current needs without compromising future generations' ability to meet theirs
3. Using technology to grow the economy as fast as possible
4. Relocating industry away from cities
Show answer
Answer: Meeting current needs without compromising future generations' ability to meet theirs
Sustainable development was defined by the 1987 Brundtland Commission report as 'development that meets the needs of the present without compromising the ability of future generations to meet their own needs.' It's the foundational concept behind the UN's Sustainable Development Goals (SDGs).
