Hi folks! Humans have a history of controlling “undesirable” species, like predators perceived as destructive to domestic animals. In North America, predators like wolves, coyotes and birds of prey have been extensively shot and trapped, sometimes to near extinction.

Culling, the removal of individual animals from a population, is sometimes used in wildlife management for population control. What is your opinion on culling of wildlife populations in regard to ecological and ethical considerations? Is there a time that it is appropriate? Please feel free to do some independent research. For some insight, please see the video below on active management to address a disease epidemic in an African nature reserve (click cc on the bottom right of the video to enable closed captioning).

A separate post to the initial discussion question (50% of grade) and reply to another student (50% of grade) are required for this discussion board.  Please include the name of the person or question to which you are replying in the subject line. For example, “Tom’s response to Susan’s comment.”

Please note: APA format and references are not required for discussions. This is a college-level course and I expect that all discussion board posts and replies are written in complete sentences using proper grammar, punctuation and spelling. Please refrain from submitting “I agree” replies that essentially restate another student’s post. Substantive points will be deducted for restated replies

DB 5

Hi folks! Forests cover about 30% of the Earth’s land area and provide an enormous quantity of products and services. Discuss at least two benefits that humans derive from forests. How are these benefits affected by forest fragmentation and deforestation? Do you think humans also lose an important habitat as natural lands are lost to development? Please feel free to do some independent research. For some insight, please see the video below on forest fragmentation in the rainforests of South America (click cc on the bottom right of the video to enable closed captioning).
