Logging in forests can result in habitat loss for the animals in the forest. Many animals use trees and forests for a home and some animals need a large range to find enough food to survive. Logging can also result in deforestation, which means that forests are becoming smaller. Obviously, cutting down trees for logging reduces the size of forests. Tree roots are very important for holding the soil in place. Logging results in fewer trees and so soil can be eroded more easily. Therefore, logging leads to habitat loss, deforestation, and erosion. The answer is "all of the above".

There are many wilderness areas in the USA, including protected forests, state parks, and national parks. The total number is well into the hundreds, so the best answer from these four choices is "d. 474".
