-
Poaching
-
Habitat loss
-
Climate change
-
All of the above
B
Correct answer
Explanation
Habitat loss is the main cause of the critically endangered status of the mountain gorilla. The mountain gorilla's habitat is being destroyed by deforestation for agriculture and logging.

Coastal development often involves the destruction of natural habitats, such as mangrove forests and coral reefs, which are essential for the survival of marine life.
How does coastal development impact marine ecosystems?
-
It can lead to habitat destruction and fragmentation.
-
It can increase pollution and sedimentation.
-
It can disrupt natural ecological processes.
-
All of the above
D
Correct answer
Explanation
Coastal development can have a range of negative impacts on marine ecosystems, including habitat destruction, pollution, and disruption of natural ecological processes.
What are some of the key threats to coastal ecosystems?
-

What are some of the potential consequences of ignoring the need to protect coastal ecosystems?
-
Loss of biodiversity.
-
Increased coastal erosion.
-
More frequent and severe flooding.
-
All of the above
D
Correct answer
Explanation
Ignoring the need to protect coastal ecosystems can have a range of negative consequences, including loss of biodiversity, increased coastal erosion, and more frequent and severe flooding.
What is the primary cause of coral bleaching, a major threat to coral reef ecosystems?
-
Rising sea temperatures
-
Overfishing
-
Pollution
-
All of the above
A
Correct answer
Explanation

What are some of the potential consequences of failing to address the challenges of sea-level rise and coastal erosion?
-
Increased flooding and salinization of coastal land
-
Loss of coastal ecosystems and biodiversity
-
Displacement of coastal communities and infrastructure
-
All of the above
D
Correct answer
Explanation
Failing to address the challenges of sea-level rise and coastal erosion could have a number of potential consequences, including increased flooding and salinization of coastal land, loss of coastal ecosystems and biodiversity, and displacement of coastal communities and infrastructure.
