Explain why clear-cutting is a more destructive method of wood harvesting than selective cutting.
Clear-cutting removes every tree in an area, completely destroying habitat, increasing soil erosion, and preventing natural regrowth, whereas selective cutting removes only chosen mature trees and leaves the rest of the forest intact.
Which of the following is not a negative impact of pesticide use?
Explain why the populations of great apes in Africa are declining.
Great ape populations in Africa are declining mainly because of habitat loss from deforestation, logging, agriculture, and mining, along with poaching and disease spread from human contact.
Explain what type of logging would most likely necessitate reforestation afterwards.
Clear-cutting would most likely require reforestation afterward because it removes all trees, leaving the area without natural seed sources for regrowth.
What is meant by the unexpected consequences of environmental manipulation?
Unexpected consequences are the unintended, often harmful side effects that result from altering the environment, such as introducing a species that becomes invasive or pesticides that harm beneficial wildlife.

Which national park in Texas helps reduce the harmful impact of land use on the environment?
Which of the following are possible consequences of logging in forests?
Explain why biological control methods are generally environmentally superior to chemical pest control methods.
