Question

What are some human activities that bring about removal of large areas of vegetation?

Answer 1

1) conversion of forests/forestland into agricultural land or settlement area

2) rapid urbanization - wherein large tracts of land are converted into either industrial estates or housing area

Answer 2

deforistation is caused partly by urbal sprawl, when the population increases to a level where they need to expand outward into previously forest land.

the rainforests are being cut down because of three resons

1)timber, the wood that the rainforests provide bring in greatly needed money, but at the forests expense

2)animals, animals like cows and oxen need land to graze. they cannont graze in the forest, to they cut down the trees so that grass can grow for there cattle.

3)cash crops, that is, crops farmed soley for the purpose of sales to other contries. the land in south america is not furtile for crops of the kind that is in demand by the public, so the ppl move into the rainforest, cutting down the trees and farming on that land, the problem is is that the land only will produce a year or 2s harvest. then they need to move deeper into the forest.

i hope that helps

Answer 3

trees are coming down all the time ,

in My town trucks loaded with huge logs of exotic timber leave the mountains with permits bought from corrupt oficials almost nightly

we can only guess at the exatct amount but from my house we can see many bare patches on the mountains and the river is constantly muddy in the last 3 years ,because topsoils, without the protection of the forrests , is washed into the rivers ,

this is just one place and this is happening all over mexico ,the Market for the wood being the USA.

here is a general note on deforestation

CAN DEFORESTATION BE STOPPED

Almost impossible

the Indians or local people would cut everything down and burn the forrest to replace it with harmfull short term farming killing the soil in no time

expanding populations and expanding farming ,that has to keep pace with the expanding populations are very strong forces that encroach upon the rainforest's

clearing them for farming and settlement areas .

that and the giant networks of roads that have exchanged forests for asphalt all over the planet

In Mexico is a famous jungle that the Media has been trying to save for years

the Naturists ,and the government ,keep watch .laws are made for protection the wild and to forbid logging.

TV put out a series of documentaries

there are campaigns in the News papers

and all of this has not made the slightest difference

Rainforest's always are in third world countries and always in third world countries corruption and the need for money s highest

the jungle gets smaller by the day

more and more farmers move in .and burn the trees

it is an impossible situation

as long as there is poverty and an increasing birth rate in these regions the destruction will continue

they are too easily tempted to sell of exotic animals to the unscroupelous people who buy them.for the market that exists in the USA.

we must look for ways to improve economic situations on the edges of Nature .

the only way to preserve the forrest is to devellop eco tourism under strict control that has limited acces ,and use the local people in the concept as guides ,hotel staff and get them to start home industries of artifacts .

eco tourism is the only concept that profits by a healthy back ground with out harming it

REFORRESTATION

we must reforrest and at the same time reduce our carbon emissions.

most governments are aware of these and many first world countries now include programs to reduce their carbon emissions.

the world bank pays large subsidies for farmers to plant trees especially a tree called Paulownia elongate carolinia,because it is one of the better ones that capture carbon.

IN THE PAST

the sahara used to be forrests

arabia ,irak ,iran used to be fertile lands in biblical times

Ghengas Kahn burned all the forrests here and filled the well with water and so turning vast lands into dessert.

the Spanish Armada deforested Spain

.the Phoenician fleet deforested Lebanon

Madagascar a botanic paradise is now destroyed

the exotic animals sold or killed ,the forest slash and burned for agriculture ,the coastal water poluted by topsoils washed fronm the denuded moutains by the rains.

many many countries in Africa (because of poverty and war as well as greedy farming )

Borneo because of the expensive timber

india ,China ,Mexico ,South Americas Amazonia,

Europe because of civilization,USA,Japan because of overpopulation,

read a planet under stress ,plan B --by Lester E Brown.

it is in an Adobe print out as well on the net. Source(s) NOTE

1000 trees that are replanted do not come anywhere near as producing the same effect or fullfilling the same function ,as far as carbon absorbtion ,production of humidity,climatic effects as the absorbtion or release of heat ,as ONE SINGLE FULLY GROWN TREE.

people keep saying we are good we cut down a thousand trees and replanted 20 thousand more

This means nothing in terms of environmental effects.

it takes at least 10 to 20 years before one of these replanted trees makes the same impact as the ones that are removed

Answer 4

the need to dump garbage, brazil wanting to catch up to the us, canada, and other higher end countries and cutting down the rain forest, and finally, global warming is causing things called 'pine beetles' to keep rising at an alarming rate and eat away at large amounts of forest.

Answer 5

There is deforestation, when we clear out huge amounts of land for settling.

Pollution also causes many plants to die.

We also dump a lot of our junk in forests and etc.

Forest fires <<self explanatory
