Deforestation and Habitat Loss

This category deals with the causes and effects of changes in natural habitat. Examples would include questions about cutting down forests, plowing grasslands for agriculture, coral reef die-offs, and the natural process of succession.

How can you save deforeststation?

we can save defarestation by banning hunts and also making forest squads.we should also put on charges to people seen cutting trees.

What are Four ways in which deforestation leads to an increase in the levels of greenhouse gases?

  1. Growing trees remove the greenhouse gas carbon dioxide (CO2) from the atmosphere, so deforestation means less CO2 is removed.
  2. Deforestation means that a lot of timber scraps are left to rot on the forest floor. Rotting timber releases either CO2 or methane, both greenhouse gases.
  3. Deforestation leaves large areas of land unprotected from floods and rainfall which can remove topsoil and small vegetation. This vegetation no longer removes CO2 from the air, but instead rots.

What are the things you like to do in the forest?

I like hiking, taking pictures of things I see, camping, watching wildlife, and looking at wildflowers. At the right time of year, I also like eating berries.

What happens to birds when trees are cut down?

They move to another tree, but if you say an entire forest of trees they will fly to somewhere far away and fly to the city and live there.

What is Concrete jungle-the increase in temperature?

concrete absorbs, and then emits heat more efficiently than many natural materials. this is most easily evident when the sun just sets. for example, walk past a concrete wall/building that faces west just after the sun sets, you can quite easily feel heat being emitted from the concrete. (just like rocks in nature, really.) if you touch a tree just next to/near the wall you will feel it is comparatively quite cold. this is all pretty much common sense. but it effects the temperature measurements quite immensely.

many places where temperature was measured many years ago were urban areas. (for example, london in the 1800s. back then there werent as many buildings/concrete/roads etc...) now, if you measure the temp at the same place today, the temp is greater, due to the 'concrete jungle effect'. obviously, comparing these two measurements is void, as the environment in which the measurement has been taken is drastically different. yet advocates of climate change dont really acknowledge this as anything major (pretty stupidly). a better measure of the temperature of the earth is measuring temperatures either in rural areas, or at sea. if you do look at these measurements, the earths temperature appears either stable, or slightly cooling.

the concrete jungle has little effect on the actually temperature of the earth. it only effects the measurements we make. and it effects the measurements quite a large amount

Are trees nonrenewable?

Trees are a renewable resource that needs to be managed for it to be sustainable. Their are many responsible people and companies that plant more trees than they cut down. As long as this continues, trees will be a renewable resource.

Why are many of the local ranchers opposed to the wolves being reintroduced?

Wolves have a habit of taking the easiest prey. Domesticated animals are not only penned - where they can't run away and are always in the same area - they are not too bright when it comes to running away from danger. (We bred them to be fairly dumb because they're easier to work with that way). Certainly it's easier for a wolf to catch and kill a fat, overfed cow than a sleek and quick elk.

The life of a single steer or sheep is very costly to a rancher, who loses not only the value of the animal at market but the value of its potential offspring. However, the U.S. government has a program to compensate ranchers for animals killed by wolves, and laws exist to permit ranchers to shoot wolves that attack their livestock. Ranchers have occasionally made an (illegal) habit of baiting wolves so they can shoot them.

Hunters, especially elk hunters, are often opposed to wolf reintroductions because wolves decrease elk populations. While wolves will most often target the weakest animals, hunters strongly dislike the pressure on the species because it makes their seasonal pastime more difficult, less enjoyable, and less bountiful.

The reintroduction of wolves into Yellowstone National Park was a huge success for a number of reasons: it allowed a viable population of one of the park's formerly native animals to survive, and remarkably, vegetation improved as elk and deer were forced to change their grazing habits. However, as time has gone on, the wolf population has grown and expanded its range to a point where it is more frequently causing (expensive) problems for ranchers adjacent to the park. Part of the anger and frustration for the ranchers stems from the conflict between federal and local government (Yellowstone is federally-managed) as the federal government is seen as detached and uninterested in local affairs.

Wolf repopulation efforts have been successful in Minnesota and Wisconsin, and more wolves are appearing in the northern Rocky Mountains of Idaho and Montana. Although wolves are inconvenient to a few highly vocal individuals, it is worth recognizing that the wolf formerly lived throughout the United States but now inhabits only a few minuscule fragments of its former range. In the place of wolves, coyotes have expanded their range and now live in every U.S. state except Hawaii.

What are animals that live in trees called?

They are called aboreals, and live in trees to stay safe (as you may well know). Some, I say, are just lazy. :) *COUGH sloth*

If a tree is cut down how might it release its carbon back into the atmosphere?

We are cutting down forests (deforestation). This is making the problem worse because the trees take up the carbon dioxide (during photosynthesis). when the tree dies, they release carbon dioxide back to the atmosphere.
