The maps shown here chronicle the loss of old-growth forest (more than 200 years old) that occurred in the United States. In your opinion, under what conditions is it ethical for conservationists who live in the United States to lobby government officials in Brazil, Indonesia, and other tropical countries to slow the rate of loss of old-growth forest?

Hello, everyone here We have a question telling us Borneo, A large Southeast Asian Island was once completely forced ID in 1900 however, only one third of the forest remained by 2020. Which of the following activities do you believe is to blame for this a cutting down the valuable hardwood trees? This is true B. Palm oil plantations. There is a large scale conversion of tropical force to oil palm plantations, so this is true. See wildfires, Borneo has lost a significant portion of its force to fires, so C. Is true. So our answer here is the all of the above. Thank you for watching. Bye.

Suppose that record snows blanket your campus this winter. Your friend says this is proof that global warming isn't really occurring. What is the flaw in your friend's logic? a. The average temperature of the Earth is not actually increasing. b. Global warming refers to temperatures, but snow is a type of precipitation. c. While the average global temperature is increasing, local temperatures and precipitation (weather) will vary. d. Your friend is confusing global warming and global climate change.

Textbook Question

The population size of mountain pine beetles in the American Northwest has long been held in check by freezing temperatures during the winters. As winters warm, populations of pine beetles are increasing, killing whitebark pine forest. Grizzly bears rely on the nuts of whitebark pine trees. Do you think climate change is affecting the fitness of the grizzly bear population?


a. No, because climate change is affecting the beetles, not the bears.

b. Yes, because climate change is decreasing the food supply of the bears, which means they will be less strong.

c. Yes, because climate change is decreasing the food supply of the bears, which is likely to reduce their ability to survive or reproduce.

Textbook Question

During the Carboniferous period, plant growth was extensive but rates of decomposition slowed (probably due to the formation of vast, oxygen-poor swamp habitats). As a result, large amounts of biomass accumulated in terrestrial environments (much of this biomass is now coal). The fossil record indicates that atmospheric oxygen increased, atmospheric carbon dioxide decreased, and global temperatures dropped. Explain why.
