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.

Why are ecological footprints higher in some countries and lower in others?
Some industrialize, which causes mining and pollution, and some do not.
What mechanized methods are used in logging?
Huge "feller-bunches" are built like tanks and have enormous "scissors" mounted on the front; they are able to snip mature trees and lay them down carefully
What are the steps to prevent environmental degradation regarding deforestation and acid rains?
* Contact Your Government - Tell your local officials that you want information on the community's water supply and local polluters. Make sure officials recognize your right to know about your water supply. * Dispose of Hazardous Waste - Make sure that hazardous waste is properly disposed of, not simply left around or placed with other garbage. * Don't Dump Chemicals - Never pour toxic substances down the drain. Although water is cleaned, cities do not have the equipment to eliminate all toxic substances from the water supply. * Find Your Water's Source - Learn about where your community's water comes from. Keep a close eye on this water source and encourage others to do the same. * Read Well Reports - Community well operators often produce monitoring reports on the safety of local wells. Ask the operators to give you a copy of these materials and stay up-to-date on your wells. * Substitute Substances - You can make your own non-toxic versions of many popular products, such as insect repellents. Doing so prevents the toxic chemicals found in these products from entering the environment and the water supply. * Test Your Water - Especially if your water comes from a private well, you should perform periodic tests for bacteria, metals, and toxic chemicals. * Use Nontoxic Substances - If you can avoid purchasing products containing toxic chemicals, do so. Otherwise, there is a threat that these chemicals could enter the environment and the water supply.
What are three things that keep a maple tree alive?
It needs carbon dioxide, sunlight, and water, all of which are required for photosynthesis.
Answer: Things that are or were alive. Answer:Biotic probably does not include resources that were alive in the very distant past (coal, petroleum oils, amber) Some resources would be hard to position (e.g methane) as it could be from present decomposition (landfills), or ancient decomp like natural gas Peat is probably biotic as it is from the reasonably distant past but still being formed today
What is involved in an ambulatory electroencephalography?
individuals are hooked up to a portable cassette recorder. They then go about normal activities and take normal rest and sleep for a period of up to 24 hours.
Is deforestation a cause of soil erosion because it leaves the soil bare and exposed?
Yes, plus it also removes the tree roots that hold the soil together.
How many men have died cutting down trees?
In 2007 it was recorded that 1,285 deaths occurred as a result of tree cutting and maintenance.
Because of using pestisides they vanishes the fertertility level of soil, which causes only few years for giving nutrients to the farmers of that region.
How can we consider deforestation as a reversible change?
Although trees can be replanted and they will regrow given time, you can not consider deforestation as a reversible change if it has gone too far.
A forest is a living ecosystem of which the trees are just one part, if that ecosystem (all the animals and other plants) is destroyed, there is NO WAY to get back to how things were, the change is irreversible.
What is the name of a tool that is used to cut paper in school?
A common tool used to cut paper in schools is a pair of scissors. Another tool often used is a paper cutter or guillotine, which allows for straight cuts on larger stacks of paper. Both tools are essential for various school projects and activities.
How long does it take a plant to grow 3 inches?
How long it takes a plant to grow three inches depends on the plant. Mile A Minute plant can grow three inches in an hour.
Which statement describes one effect of deforestation?
One of the effects of deforestation is increased global warming.
What happens when the water table drops?
Plants may die because the roots cannot reach ground water. Expenses may rise for well owners because the wells cannot reach ground water and river/lake beds dry up. This can happen in times of drought or if overpopulation in an area results in too many people drawing water out of the ground faster than it can be replenished by rainfall.
What are the main causes of habitat loss?
The loss of habitats is caused by the planet continually changing, causing habitats to be altered and modified. Natural changes tend to happen at a gradual pace, usually causing only a slight impact on wildlife. However when these changes occur at a fast pace, there is little or even no time for wildlife to react and adjust to the new environmental changes. This can result into a disaster, and for this reason, rapid habitat loss is the primary cause of the endangerment of species. However the strongest force in rapid habitat loss is the human itself. About every region of the earth has been affected by human activity in both positive and negative ways. Especially during this past century, including the loss of microbes in soil that formerly support tropical forests, as well as the extinction of fish and various aquatic species in polluted habitats caused by boats and ships. Also the changes in global climate brought about by the release of greenhouse gasses which is a result of human activity causing habitat loss.

What physical factors are unique to the tundra?
The tundra has more than one type of biome. An Alpine tundra, like the Rocky Mountains, is incredibly cold. Trees are unable to survive the severe winter weather- frozen soil, ice winds and UV radiation. There are shrubs that grow in these biomes though.
The tundra is the farthest north of all the world's biomes.
The winter temperatures average about -30 F throughout most of the true Arctic including the North Pole. The coldest weather occurs in northeastern Siberia. There January temperatures average -40 F, and have reached -93 F. Most other parts of Siberia and the sub arctic sections of central Asia, Canada, and central Alaska have an average winter temperatures of about -20 F. The mildest winters occur in the coastal regions of the Pacific Oceans, where January temperatures average about 30 F.
These same regions have mild summers, with average temperatures of about 45 F. The warmest summers occur in the inland regions of Siberia, Alaska, and Canada. July temperatures there average around 60 F. Weather stations have recorded temperatures of 90 F and above in these regions.
Winter storms develop chiefly in two areas where the barometric pressures remains low. One of these areas, called the Aleutian low, extends from eastern Siberia to the Gulf of Alaska. The other, the Icelandic low, covers central Canada, half of the Arctic Ocean, and parts of the North Atlantic Ocean and northern Europe. Storms beginning in these areas tend to travel from northwest to southwest.
Rainfall in many arctic regions totals six to ten inches a year, including melted snow. This is less rain than falls on some of the world's greatest deserts! Much of the arctic has rain and fog in the summer. In spite of the low annual rainfall, arctic lands may be very wet underfoot because the moisture evaporates slowly and drainage conditions are poor. There is also a lot of permafrost, ice that never goes away in the ground that is usually about five feet deep.
What is the main issue in deforestation?
The main issue of deforestation is the effect it has on the environment, including animal habitat, the CO2/oxygen balance, environmental factors such as erosion, etc.
What can hardwoods be used for?
Hardwoods have a huge variety of usage. From building houses to creating boats, furnitures, and even musical instruments. They are also perfect for fuels and manufacturing of charcoal. Hardwoods can also be use in making weapons, kitchen utensils and barrels. The most commonly use hardwood right now is the oak beam which can also be use in several different useful ways.
