Chapter 16, Problem 2GFO
Summary Introduction
Introduction:
Preserving biodiversity is an astonishing challenge, which must be fulfilled by a deeper understanding of biodiversity itself, application of different preservation strategies, and changes in human behavior and beliefs. The threats to biodiversity have been identified for some time now. At present, the prime attempts in preserving biodiversity comprise legislative methods to monitor corporate and human behavior, habitat restoration, and setting aside safeguarded regions.

Students have asked these similar questions
(15)The text book gives many details about problems with the threats to biodiversity on planet
Earth, but one problem which may be inherent in their analysis is (a) they fail to note that
biodiversity loss involves population declines (b) they fail to consider human beings as part of
the ecosystems that they survey (c) they fail to note that extinction is reversible (d) they fail to
point out that if trends continue, we may see the extinction of more than half of all species
Choose the statement that is most likely made by an environmentalist rather than by an environmental scientist.
"On average, 52 animal species move one step closer to extinction each year because of overpopulation and habitat destruction.”
“Human population growth is a current environmental issue, as is climate change.”
“When the number of existing humans exceeds the carrying capacity of the planet, we have reached the state of overpopulation.”
“Citizens must take matters into their own hands and start having fewer children to reduce the world’s population, starting now.”
A conservation biologist has been asked to explain why it is important to protect biodiversity. She would list all of the following reasons except for which one?
A. Humans are dependent on many species for food, medicines, fiber, and other necessities.
B. Biodiversity can be exploited indefinitely for the profit of humans.
C. Other species have inherent value and humans have a moral obligation to protect them.
D. Biodiverse ecosystems provide ecosystem services that sustain all life on Earth.
E. Biodiversity provides emotional and physical health benefits by providing places for humans to visit for wonder, insight, and exercise.

- Which of the following best predicts the consequences of introducing brown rats ( invasive species) to an island where they did not previously exist? Choose 1 answer: Choose 1 answer: (Choice A) A The rat population size will likely remain small, and as a result the rats will not be able to outcompete other organisms for resources. (Choice B) B Without its typical food sources, the rat population will not be able to become established, and the island ecosystem will remain stable. (Choice C) The rat population will grow rapidly, disrupting the island's community structure by feeding on native plants and animals. (Choice D) D Without any natural predators, the rat population will become established and help increase the species diversity of the island answer explainarrow_forward(A) The above figure indicates how much biologically productive land is needed to support different activities (e.g. 'carbon' is land needed to offset carbon emissions from energy production; 'cropland' is land needed to grow crops for food).
