Deforestation and Habitat Loss

First a short bit on what polyethylene is:

Polyethylene is a long chained organic molecule that is formed from ethylene (H2C=CH2).It contains no other materials than Carbon and Hydrogen. The basic building block (ethylene) is a non toxic gas that can act as a hormone in plant growth, speeding ripening and the rowth of seedlings.

The harmful effects of polyethylene are more related to the forms that it is made into - films, ropes, six-pack holders, milk jugs etc. As trash it is refractory in the environment, lasting for many years without decomposition except if it is exposed to sunlight. As trash, due to its shapes it has been observed to trap animals legs and heads.

If collected it can be easiiy recycled reducing the need for consumption of fresh raw materials and energy. If burned, it is converted to carbon dioxide and water.

Rags were pounded into pulp with hammers, and placed in water. The mixture was constantly stirred so it would never settle in the bottom. After a certain amount of time, the mixture was poured out and put in a special machine, (i think...) and the color depended on the rags and water. Later about 1770, when rags became scarce because of the amount of paper makers, different things were tried. Wood was finally discovered and that's how we make it today!

Nevada. Nevada is 91.9% federal lands - 101, 611 sq miles worth. Even though much larger, California has less federal land (46.9% or 76, 778 sq. miles. Compare to 29.6% of all land in the US being owned by the federal government.

Pretty much all the food we buy at the grocery store is grown or raised somewhere, increasingly, also, the smarter farmers have gotten wind of how people are into herbal supplements these days, and some farms are growing herbs now.

Sawmills were once a common sight in the United States, however heavy deforestation means that they are now located only in heavily wooded areas, generally near tree farms. Sawmills have existed since the development of water and wind power, which enabled large saw blades to cut large logs. Some of the first ever built were built in Germany and England, to clear out the once abundant forests and turn the wood into sailing ships and houses. However, the sawmill did not become common until the invention of the steam engine, since steam engines could power a sawmill off of the wood chips, bark and sawdust created by the mill itself.

The invention of modern sawmills in the 1800s permitted for much of the United States and Europe to become heavily deforested. Once it was possible to cut down and process wood into finished boards on-site, demand for cheap, pre-cut lumber skyrocketed. This eventually evolved into the modern sawmill, which can convert an entire forest of trees into lumber through a largely automated process. The use of automated saws not only saves time and money, it prevents workers from becoming injured by keeping them away from the large blades and spinning machines.

The downside is that this means that all of the logs must be of similar size, shape and thickness. This has led to the development of the modern tree farm. Such tree farms produce trees that are not only identical in species; they are identical in height and thickness. While good for the sawmill, these artificial forests tend to be unwelcoming to wild animals, since they lack biodiversity and the undergrowth must be cleared constantly to prevent fires. Still, the advent of tree farming has largely been hailed as a success for the natural environment, since it permits the demand for wood to be satisfied without creating a need for new forests to be cut down.

Many sawmills are somewhat open to the public. In such cases, they have lumber lots where any person may purchase lumber at prevailing market rates. Persons who know they will be purchasing a large amount of lumber to build a deck or a house can often save money by going directly to a local sawmill.

There are many environmental factors that might have a big impact on a restaurant. Pollution of the air, water, or environment could have the biggest impacts.

Forests add humidity to the air, so when trees are removed, the air gets hotter, and leads to climate change....which causes a decline in precipitation.....which causes drought....which disrupts cropping programs and kills livestock....so this puts a bad effect on the economy

i do not no

40%

Rain fall will reduce if deforeststion occur largely. bcoz it is said that canopy of tall trees ar attract clouds. alos it is observed that the rainfall is more in forest region due to more numbers of trees. hence trees are very necessary for mean average rainfall. due large deforeststion rainfall is reduced considerabially after industrilization.

The burning of carbon based fuels causes CO2 gas to build up in our atmosphere, normally plants take in the CO2, using the carbon portion in photosynthesis and releasing O2 which we breathe in and expel CO2 ourselves, before the industrial age and the burning of fuels there was an atmospheric balance, but since the start of burning coal, petroleum and gases we have been pumping more CO2 into the atmosphere which is causing solar rays to get trapped. This is causing an increase in global temperature.

rate of deforestation

One reason people buy trees is to landscape their yards and property with species of trees they desire, or to plant trees that will grow together to make a windbreak. People buy fruit trees to have their own fruit or to have an orchard to sell fruit. Those who wish to grow and sell Christmas trees buy them when they are very small and harvest them when they are good heights for Christmas trees.

about 1000

im pretty sure that deforestation is when people chop down trees in one large area of a forest. problems this can cause are mostly environmental, for example, alot of animals make their homes in trees and if the trees are cut down then they will have no where else to live. also, oxygen comes from trees and without the trees there will be no oxygen, and without the oxygen, we will all die. :) hope that helped.

Tarzan and George of the Jungle are planting trees to help with deforestation, so they are saving the whole wide world. Mowgle helps at the weekends but is at school in the week. keep cutting down trees, we are fine, we are being saved

The answer is yes. No matter what the area it can always be affected by deforestation in some shape or form.

Good examples of this is the Amazon Rainforest. Local businesses cut down trees locally to cut down costs and transportation to serve the local community.

What is notable is that rural deforestation is harder to monitor and control and so makes it more appealing.

More information is available from the NASA Earth Observatory.

The average temperature of a swamp is 90 degrees Fahrenheit

Most habitat has been altered in order to convert it to some other purpose useful for humans. The production of food is the first and foremost reason wildlands are "destroyed," and I think you will agree that food is a necessity. In some cases, valleys are flooded when we create reservoirs with dams; these dams provide an aquifer of water for times when water is more scarce and may provide electrical power.

The meaning of ecological problems refers to problems in the environment. They are the problems that relate to ecology and include conservation and climate change.

there are many reasons countries cut down trees. One reason is to make shelter, such as a house. Another reason is to have firewood, and even paper!
