Deck 8: Pollution

Question 1

Earth is currently experiencing a mass extinction.

Answer 1

True

Question 2

A small population is vulnerable to increased genetic defects.

Answer 2

True

Question 3

Increased biodiversity has followed past mass extinctions.

Answer 3

True

Question 4

It is better to eat seafood than other protein sources because fishing has relatively few environmental impacts.

Question 5

When trying to preserve habitat, two small patches are as valuable as one large patch as long as the total area is the same.

Question 6

All non-native species are considered invasive.

Question 7

Harvesting of old-growth forests has minimal impact when the forests are replaced by tree farms of the same size.

Question 8

One goal of conservation is to try to prevent disturbances from occurring.

Question 9

Resilience is the capacity of a system to accommodate change and still retain its essential function, structure, and identity.

Question 10

Once a species is so at risk that it becomes endangered, it cannot be removed from the endangered species list.

Question 11

It is possible for one species to be both a keystone species and an umbrella species.

Question 12

Developers can buy and sell credits in a wetland mitigation bank.

Question 13

One important goal of restoration efforts is to reconnect fragmented habitat patches.

Question 14

One important goal of stream restoration is simply to remove obstacles in order to allow a self-sustaining, dynamic stream system.

Question 15

The most effective way to reverse species extinctions is to protect more wilderness areas.

Question 16

Reconciliation ecology is an approach to restoration which helps humans and other species live together.

Question 17

Pleistocene rewilding has been tested and proven to be impossible.

Question 18

Biodiversity

A) is the variety of genes, species, and ecosystems in an area.
B) is a major factor in ecosystem resilience
C) is impacted by habitat destruction
D) all of the above

Question 19

The background rate of extinction is approximately

A) one per million species per year
B) one in a hundred species per year
C) zero
D) not known

Question 20

The Anthropocene is

A) an informal term for the current epoch
B) the official title for the geological epoch that followed the Holocene
C) the age of the dinosaurs
D) the future era, beginning approximately 2100 CE

Question 21

The primary causes of biodiversity loss are sometimes abbreviated using the acronym

A) IPAT
B) HIPPO
C) CHNOPS
D) CHP

Question 22

Buildling roads into previously inaccessible forests is a problem because of

A) pollution
B) temperature changes
C) moisture changes
D) fragmentation

Question 23

The goal of restoration is

A) to stop change from occurring
B) to move an ecosystem back to the state it occupied approximately 100 years earlier
C) to move an ecosystem back to the state it occupied approximately 200 years earlier
D) to provide conditions to allow a system to achieve a state of equilbrium that results in a healthy, self-sustaining system
