Question 1

Define the ecological consequences of wildfires.

Answer 1

Wildfires can lead to changes in species distribution, loss of biodiversity, and the collapse of ecosystems.

Question 2

Describe the potential long-term effects of wildfires on ecosystems.

Answer 2

Long-term effects can include ecosystem collapse and significant changes in species distribution.

Question 3

Describe the concept of direct exploitation for food.

Answer 3

Direct exploitation for food refers to the practice of harvesting wild animals and fish for human consumption, which can include activities like overfishing and hunting for bush meat.

Question 4

Explain the term ‘overfishing’ and its implications.

Answer 4

Overfishing is the practice of catching fish at a rate that exceeds their natural ability to reproduce, leading to a decline in fish populations and threatening marine ecosystems.

Question 5

Define ‘bycatch’ and its impact on marine life.

Answer 5

The unintended capture of non-target species in fishing operations. Bycatch often results in the death or injury of these animals, and it can also impact the sustainability of fisheries and the health of ocean ecosystems

Question 6

How does bush meat harvesting affect wildlife populations?

Answer 6

Bush meat harvesting can threaten wildlife populations by reducing the numbers of large mammals and primates, often leading to unsustainable practices that endanger species.

Question 7

Identify the types of species threatened by exploitation and overharvest.

Answer 7

Exploitation and overharvest threaten many large mammals and primates, as well as various marine species due to practices like overfishing and bycatch.
