The loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for indigenous people.

What is deforestation and its effects?
Deforestation refers to the decrease in forest areas across the world that are lost for other uses such as agricultural croplands, urbanization, or mining activities. Greatly accelerated by human activities since 1960, deforestation has been negatively affecting natural ecosystems, biodiversity, and the climate.
What are the 5 main causes of deforestation?
The most common pressures causing deforestation and severe forest degradation are agriculture, unsustainable forest management, mining, infrastructure projects and increased fire incidence and intensity.
How important is deforestation?
As climate change continues, trees play an important role in carbon sequestration, or the capture and storage of excess carbon dioxide. ... Deforestation not only removes vegetation that is important for removing carbon dioxide from the air, but the act of clearing the forests also produces greenhouse gas emissions.
What is the effect of deforestation on humans?
But deforestation is having another worrisome effect: an increase in the spread of life-threatening diseases such as malaria and dengue fever. For a host of ecological reasons, the loss of forest can act as an incubator for insect-borne and other infectious diseases that afflict humans.
What are the 4 effects of deforestation?
The loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for indigenous people.
How does deforestation affect wildlife?
Deforestation can directly lead to biodiversity loss when animal species that live in the trees no longer have their habitat, cannot relocate, and therefore become extinct. Deforestation can lead certain tree species to permanently disappear, which affects biodiversity of plant species in an environment.
What is the main function of forest?
Forests provide us with shelter, livelihoods, water, food and fuel security. All these activities directly or indirectly involve forests. Some are easy to figure out - fruits, paper and wood from trees, and so on.
What happens if deforestation stopped?
If we don't stop deforestation, more than half of our plant and animal species will be extinct. It is the oldest ecosystem on Earth and they are impossible to replace. It took millions of years for rainforests to develop… how can we replenish fast enough to cope with the rate of deforestation?
How does deforestation cause flooding?
When deforestation takes place, the top layer of soil can be dislodged – this is also known as soil erosion. When the top layer of soil is unstable, it is unable to retain any of the water that falls on it, resulting in increased surface run-off, which, in turn, increases the risk of flooding.
How does deforestation affect global warming?
The trees of tropical forests, like all green plants, take up carbon dioxide from the atmosphere and release oxygen during photosynthesis. ... When forests are cut down, much of that stored carbon is released into the atmosphere again as CO2. This is how deforestation and forest degradation contribute to global warming.
Why is deforestation harmful for the environment?
Removal or depletion of trees results in climatic changes, the disappearance of wildlife, soil erosion and greenhouse gases emissions, etc. Loss of trees adversely affects every biological life in all possible ways. With time, these become more prominent to humankind, as well as other species inhabiting this planet.
