- Why do people cut down rain forest trees? A: People cut down rain forest trees to build roads, harvest timber, and clear land for livestock grazing, agricultural production and urban development. The poor clear forests to create subsistence farms, and large commercial enterprises clear tracts of land for industrial-scale mechanical farming. Keep Learning.

- After deforestation, the water stays on top of the soil, which can cause floods. Trees absorb water and give out some moisture to the atmosphere. When trees are chopped down, the rivers etc dry out and drought occurs. Birds, insects and animals lose their homes.

WWFAbout Us How to HelpSearchSearch wDonate AdoptOur Work Species Places Each year, millions of acres of forest around the world are destroyed or degraded by fire. The same amount is lost to logging and agriculture combined. Fire is often used as a way to clear land for other uses such as planting crops.

- A: Cutting down trees severely affects the habitats of forest-dwelling flora and fauna, which can eventually lead to extinction of vulnerable species. In addition to causing soil erosion, deforestation also results in larger amounts of greenhouse gases reaching the atmosphere because trees cannot absorb carbon dioxide once they’re cut down.

- The reasons for deforestation: 1  To provide timber as a fuel or a building material. 2  To provide extra land for agriculture. This agricultural land is often used to grow rice in paddy fields or to rear cattle in order to satisfy the increasing demand for food.

Lyrfutures08âs Weblog Deforestation causes multiple social and environmental issues. Recently, there has been a growing recognition that immediate and short-term impacts of deforestation jeopardize our lives on Earth. Therefore, it is imperative for us to understand the effects of deforestation on our lives and environment, and utilize the knowledge in with finding effective solutions. First of all, deforestation contributes to an alternation of local and global climate through: Disruption of Natural Cycle. Carbon Cycle. Now we all know that carbon dioxide (CO2) is one of the major contributors to the greenhouse effect (Global Warming). Deforestation, though not widely known, is directly connected to disruption of carbon cycle. The carbon cycle is the movement of carbon between the abiotic environment (the atmosphere and oceans) and living organisms (see figure 1.0)Forests serve as a major carbon store as CO2 is taken up from the atmosphere and used to produce fats, proteins and carbohydrates that constitute trees.

Deforestation Deforestation occurs for many reasons: trees are cut down to be used or sold as fuel (sometimes in the form of charcoal) or timber, while cleared land is used as pasture for livestock, plantations of commodities and settlements.thers state that tropical rainforest deforestation is contributing to the ongoing Holocene mass extinction. The known extinction rates from deforestation rates are very low, approximately 1 species per year from mammals and birds which extrapolates to approximately 23,000 species per year for all species.

- As global demand for products like wood, paper, beef and palm oil continues to rise, companies are encroaching ever deeper into the world’s dwindling forests. Read more. All of us need forests. Millions of people live in and depend on them for almost everything, from food to medicine to shelter. Forests also absorb the carbon dioxide we emit from cars, planes and power plants, making them critical in the global fight against climate change. Yet every single minute an area of forest the size of fifty soccer fields is cut down...

Even localized deforestation can result in extinctions as many unique species exist in small isolated geographic locations in the world.

Deforestation: Facts, Causes & Effects When they are degraded, it can set off a devastating chain of events both locally and around the world. Loss of species: Seventy percent of the world’s plants and animals live in forests and are losing their habitats to deforestation, according to National Geographic.Loss of habitat can lead to species extinction.he impact of deforestation on the exchange of water vapor and carbon dioxide between the atmosphere and the terrestrial land surface is the biggest concern with regard to the climate system, said Daley. Changes in their atmospheric concentration will have a direct effect on climate.

More than half of all plant and land animal species in the world live in tropical forests.

Tropical rainforests is where the most concentrated deforestation occurs. Almost 30% of the world is covered by forests, excluding water mass.

WWFAbout Us How to HelpSearchSearch wDonate AdoptOur Work Species Places It is estimated that 15% of all greenhouse gas emissions are the result of deforestation. Deforestation is a particular concern in tropical rainforests because these forests are home to much of the world’s biodiversity.For example, in the Amazon around 17% of the forest has been lost in the last 50 years, mostly due to forest conversion for cattle ranching.any of the world’s most threatened and endangered animals live in forests, and 1.6 billion people rely on benefits forests offer, including food, fresh water, clothing, traditional medicine and shelter. But forests around the world are under threat from deforestation, jeopardizing these benefits.

How might rain forest destruction affect our weather? It is feared that the loss of rain forests will increase CO 2 levels in the atmosphere and result in global warming. On a more local level, the clearing of rain forest land diminishes the amount of evaporation. As a result, the rainfall decreases and the ground dries out, reducing its ability to support vegetation.ain forests covered about 30 percent of the earth's land surface in 1950; the “greenbelt” is now at 7 percent and still declining. The trees are being cleared for timber, underground minerals, and farms. In the process, the great diversity of plants and animals in the rain forests is destroyed.

How does deforestation contribute to global warming? A: The destruction on forests impacts the global warming effect, as the trees and other vegetation in forests, absorb CO2 to use during photosynthesis. If the trees are being cut down, then less CO2 is being absorbed, essentially worsening the effect of global warming.

What is the normal range for hemoglobin? And for a pregnant woman 11 to 12g/dl (gram per deciliter) is the normal range of hemoglobin. Hemoglobin levels are often measured in grammes per decilitre (g/dl).  In a children 11 to 16gm/dl (gram per deciliter).    And for a pregnant woman 11 to 12g/dl (gram per deciliter) is the  normal range of hemoglobin.    If the hemoglobin is below normal, this is called anemia. But  nothing to worry.

- Effects of Deforestation. 1  Tree roots cause gaps in the soil. This enables water and air to reach roots of plants. 2  Trees absorb water and give out some moisture to the atmosphere. When trees are chopped down, the rivers etc dry out and drought occurs. 3  Birds, insects and animals lose their homes.

Habitat destruction It is a process of natural environmental change that may be caused by habitat fragmentation, geological processes, climate change or by human activities such as the introduction of invasive species, ecosystem nutrient depletion, and other human activities mentioned below.ther forest ecosystems have suffered as much or more destruction as tropical rainforests. Farming and logging have severely disturbed at least 94% of temperate broadleaf forests; many old growth forest stands have lost more than 98% of their previous area because of human activities.

- Deforestation has some important consequences: 1  It reduces the rate at which carbon dioxide is absorbed and ‘locked away’ in the plant biomass by photosynthesis, as there are fewer trees. 2  As timber is burnt to clear space, it increases the release of carbon dioxide into the atmosphere.
