1) Farming can cause soil erosion: \ne.g. Deforestation removes roots holding soil and allows extensive wind and water damage. \n\n2) Farming causes desertification: \nThis is when a desert gradually spreads to the surrounding areas of semi-desert, making them true desert! \n\n3) Chemical pollution and habitat destruction are major problems: \nCareless use of fertilisers pollutes rivers and lakes, making them green, slimy and horrible. \n\n4) Irrigation can cause environmental problems:\ncreating dams involves flooding large areas. Wildlife habitats are destroyed and people have to be resettled! \n\nHope I helped!

Here is a brief overview of the Pampas and some of the reasons why the area is endangered, in addition to immigration and the expansion of communities/suburbia into these areas:  http://www.blueplanetbiomes.org/pampas.htm\n\nGood luck!

It is called a rain forest because at the end of the day you will find that it will always rain. The sun heats the earth and warms the air above it. As it rises it cools and forms clouds. By the time this has happened it is the end of the day and it starts to pour down. The sun only heats the earth to a temperature high enough near the equator because that part is nearest the sun. You won't find this happening anywhere else except the equator and so you don't find tropical rainforests anywhere esle.

Geography homework huh.\n\nBroadly.\n\n1) Improper removal of stubble or fallow cover leading to  erosion.\n\n2) Insufficient fallow time leading to decline in soil fertility.\n\n3) Over removal of tree cover leading to water table elevation and/or salinity.\n\n4) Over production of single crop types crops leading to nutrient depletion.\n\n5) Over-irrigation leading to turbidity and and slainity in irriagtion water sources.\n\n6) Failure to control tree growth within catchment leading to excess infiltration and loss of runoof. Irrigation water fails.\n\n7) Excess tillage of fragile soils leading to erosion.\n\n8) Tillage of soils in anticipation of  planting conditions that fail to transpire. Ground remains loose and without plant cover for extended periods and erodes.\n\n9) Overgrazing leading to desertification which encroaches on arable land.\n\nThat probably covers most of the practices that have caused land loss in the poast 6000 years.

aww i hate that. the rainforest are already reduced to a 4% of the entire world area and they still want to cut. get the National wildlife and forestn preservation for support.

Deforestation led to poor soil quality led to the formation of deserts. Don't be an idiot.

In addition to rainforests--coral reefs. Over-fishing, pollution, and warming are negatively impacting the reefs in many parts of the world.

Wikipedia has a complete overview of it; including causes and the aftermath. I linked it below for you.

Condition that they shud be planted again...else they are no longer renewable source with rapid destruction of forests. As they grow again n again they are renewable.

I'm not sure about the rainforest portion, but this site had some good info:\nhttp://www.frontiercoop.com/learn/eo_patchouli.html

Deforestation\n\nThe deforestation is a war against the mother nature, it brings all of our human miseries and it affects to every souls of our world. It changes the climate, brings flood, drought, destroys habitation of wildlife, destroys many plants and animals. Deforestation is the beginning of destruction of lives in our world. It is a war against our lives.

Rainforests sure get a lot...hence their name!\nAlso, amazingly, deserts get a lot of flash floods!\nHope I helped

People are not understanding the importance of the tropical forests which helps for good rain fall.Instead of saving them they are destroying.It is so shameful.

It is very cool that in our modern day world there are still parts of the are is still unexopled with many undiscovred plants and animals. I reminds me alot of Sir Colon Doyle's lost world. This must have how it been when europeans founded the amazon and reported back to europe.  I just hope they keep it nice and not let to many people go into it and explore it. Because if they they will probably destroy it or deminishing it's beauty and that would be a crying shame. I will cross my finger and watch joyfully to new developments.  With bad news around every bend it is good to hear something that will uplift my spirts.

(1) There are several factors which make environmental problems. Some of them are mentioned below for your knowledge.\na) Overcrowding, poor-quality housing\nb) Inadequate provision for water supply\nc) sanitation factors\nd) Different pollutions( air, water, land)\ne) Deforestation\nf) Smoke from vehicles and  factories\n\n(2) In addition to that, secondary impacts of the above mentioned factors are also make environmental problems.

If "natural" means "not man made", then the loss of biodiversity can be either natural or man made.\n\nFor example, the great biodiversity losses being currently experienced in the Amazon rain forests are primarily due to the slash and burn farming techniques by human residents of the area. Other examples include the paving of roads and parking lots, destruction of wetlands for commercial or residential property, drilling of oil wells in arctic regions which destroys the tundra, etc.\n\n"Natural" examples of biodiversity loss include cataclysmic events such as volcanoes, earthquakes, floods, storms, etc. which can wipe out vast numbers of species.\n\nHope this helps!
