Which of the following is NOT a major threat to conservation?

  1. Habitat loss and fragmentation

  2. Climate change

  3. Pollution

  4. Sustainable development


Correct Option: D
Explanation:

Sustainable development is a strategy for economic and social development that aims to meet the needs of the present without compromising the ability of future generations to meet their own needs. It is not a threat to conservation, but rather a potential solution.

What is the primary cause of habitat loss and fragmentation?

  1. Agriculture

  2. Urbanization

  3. Mining

  4. All of the above


Correct Option: D
Explanation:

Habitat loss and fragmentation can be caused by a variety of human activities, including agriculture, urbanization, mining, and other forms of development. These activities can destroy or degrade natural habitats, making them unsuitable for wildlife.

How does climate change impact biodiversity?

  1. It can cause species to lose their habitats

  2. It can disrupt food chains and ecosystems

  3. It can lead to the spread of invasive species

  4. All of the above


Correct Option: D
Explanation:

Climate change can have a wide range of negative impacts on biodiversity. It can cause species to lose their habitats, disrupt food chains and ecosystems, and lead to the spread of invasive species. These impacts can threaten the survival of many species and ecosystems.

What is the main source of pollution that threatens marine ecosystems?

  1. Oil spills

  2. Plastic waste

  3. Sewage discharge

  4. Agricultural runoff


Correct Option: B
Explanation:

Plastic waste is a major threat to marine ecosystems. It can entangle marine life, block their digestive tracts, and leach toxic chemicals into the environment. Plastic waste also contributes to the formation of microplastics, which can be ingested by marine organisms and have harmful effects on their health.

Which of the following is NOT a strategy for addressing habitat loss and fragmentation?

  1. Establishing protected areas

  2. Restoring degraded habitats

  3. Creating wildlife corridors

  4. Promoting sustainable agriculture


Correct Option: D
Explanation:

Promoting sustainable agriculture is not a direct strategy for addressing habitat loss and fragmentation. However, it can help to reduce the demand for land for agriculture, which can indirectly help to protect natural habitats.

What is the primary goal of conservation biology?

  1. To protect and restore biodiversity

  2. To manage and sustain natural resources

  3. To promote sustainable development

  4. To educate the public about environmental issues


Correct Option: A
Explanation:

The primary goal of conservation biology is to protect and restore biodiversity. This includes protecting and restoring natural habitats, managing and sustaining natural resources, promoting sustainable development, and educating the public about environmental issues.

Which of the following is NOT a type of invasive species?

  1. Non-native species

  2. Introduced species

  3. Native species

  4. Exotic species


Correct Option: C
Explanation:

Native species are species that are naturally found in a particular region. They are not invasive species. Invasive species are non-native species that have been introduced to a new region and have become a threat to the native species and ecosystems.

What is the main cause of the decline of coral reefs?

  1. Climate change

  2. Overfishing

  3. Pollution

  4. All of the above


Correct Option: D
Explanation:

The decline of coral reefs is caused by a combination of factors, including climate change, overfishing, pollution, and other human activities. Climate change is causing the ocean to become warmer and more acidic, which is harmful to corals. Overfishing can reduce the number of herbivorous fish that graze on algae, which can lead to an overgrowth of algae that can smother corals. Pollution can also harm corals and disrupt coral reef ecosystems.

What is the main goal of sustainable development?

  1. To meet the needs of the present without compromising the ability of future generations to meet their own needs

  2. To promote economic growth

  3. To protect the environment

  4. To reduce poverty


Correct Option: A
Explanation:

The main goal of sustainable development is to meet the needs of the present without compromising the ability of future generations to meet their own needs. This means that sustainable development must take into account the environmental, social, and economic impacts of our actions and ensure that we are not depleting resources or harming the environment in a way that will make it difficult for future generations to meet their needs.

Which of the following is NOT a benefit of biodiversity?

  1. It provides food and other resources for humans

  2. It helps to regulate the climate

  3. It provides medicines and other natural products

  4. It reduces the risk of natural disasters


Correct Option: D
Explanation:

Biodiversity does not directly reduce the risk of natural disasters. However, it can help to mitigate the impacts of natural disasters by providing natural buffers and resources that can help to protect communities and ecosystems.

What is the main cause of deforestation in the Amazon rainforest?

  1. Agriculture

  2. Logging

  3. Mining

  4. Climate change


Correct Option: A
Explanation:

The main cause of deforestation in the Amazon rainforest is agriculture. Large areas of the rainforest are being cleared for cattle ranching, soybean farming, and other agricultural purposes. This is leading to the loss of biodiversity, the release of greenhouse gases, and the displacement of indigenous peoples.

Which of the following is NOT a type of pollution?

  1. Air pollution

  2. Water pollution

  3. Land pollution

  4. Noise pollution


Correct Option: D
Explanation:

Noise pollution is not a type of pollution in the same way that air pollution, water pollution, and land pollution are. Noise pollution is a type of environmental disturbance that can have negative impacts on human health and well-being.

What is the main cause of the decline of amphibian populations?

  1. Habitat loss and fragmentation

  2. Climate change

  3. Pollution

  4. Disease


Correct Option: D
Explanation:

The main cause of the decline of amphibian populations is disease, particularly a fungal disease called chytridiomycosis. Chytridiomycosis is a deadly disease that affects amphibians' skin and can lead to death. It is thought to have been spread by the global trade in amphibians.

Which of the following is NOT a type of protected area?

  1. National park

  2. Wildlife sanctuary

  3. Marine protected area

  4. Biosphere reserve


Correct Option: D
Explanation:

Biosphere reserves are not protected areas in the same way that national parks, wildlife sanctuaries, and marine protected areas are. Biosphere reserves are areas that are managed to promote sustainable development and conservation. They include a core area that is protected from development, a buffer zone where sustainable development is allowed, and a transition zone where traditional land uses are allowed.

What is the main goal of the Convention on Biological Diversity?

  1. To conserve biodiversity

  2. To promote sustainable use of biodiversity

  3. To ensure the fair and equitable sharing of the benefits of biodiversity

  4. All of the above


Correct Option: D
Explanation:

The main goal of the Convention on Biological Diversity is to conserve biodiversity, promote sustainable use of biodiversity, and ensure the fair and equitable sharing of the benefits of biodiversity. The convention was adopted in 1992 and has been signed by over 190 countries.
