Landslides are almost always caused by human actions , but nature also contributes. The following are some of the causes: Deforestation on hill or mountain slopes. Crop planting practices that are not suitable for hills (for example, sowing on slopes).
Why would cutting lots of trees be a problem?
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.
Why cutting trees can cause landslide?
By clearing a large section of land by cutting down all the trees the soil is made less stable which can lead to dangerous landslides. The physical geography of rivers, mountains, and plains can all be affected by deforestation and the clear-cutting of large pieces of forest around the world.
Do trees prevent landslides?
Trees prevent floods , landslides
They help the groundwater supply recharge, prevent the transport of chemicals into streams and prevent flooding. ... The trees’ roots suck water deep from under the ground to as low as 200 feet. They hold the soil together so that erosion is prevented.
What happens if we cut more trees?
a) If we go on cutting trees: Rainfall and fertility of the soil will decrease . Changes in natural calamities will increase. It will also lead to a decrease in the water holding capacity of the soil which will result in floods.

What are effects of landslides?
The impact of a landslide can be extensive, including loss of life, destruction of infrastructure, damage to land and loss of natural resources . Landslide material can also block rivers and increase the risk of floods.
Why trees should not be cut?
Earth will lose its top fertile soil layer and get converted into desert . The ecological balance will get disturbed and floods and drought will become more frequent. Wildlife will also be affected.
What is the solution of cutting trees?
Green methods of production and utilization of resources can immeasurably reduce deforestation. Particularly, it’s the focus on re-using items, reducing the use of artificial items, and recycling more items. Paper, plastics, and wood are linked to the destruction of forests and other natural resources.
Why we should stop cutting down trees?
Cutting trees can result in the loss of habitat for animal species , which can harm ecosystems. According to National Geographic, “70 percent of Earth’s land animals and plants live in forests, and many cannot survive the deforestation that destroys their homes.”
How can we prevent landslide?
There are also various direct methods of preventing landslides; these include modifying slope geometry , using chemical agents to reinforce slope material, installing structures such as piles and retaining walls, grouting rock joints and fissures, diverting debris pathways, and rerouting surface and underwater drainage.
What kind of trees prevent landslides?
For both indices, the highest and lowest 25% of the distribution was used to classify the tree species. ‘To our surprise,’ said Hairiah, ‘ coffee was actually one of the best trees for landslide prevention, relative to its stem diameters, but pruning the coffee changes its root distribution.
How do trees reduce landslides?
With their deep roots , trees can stop erosion caused by landslides. They’re especially useful on slopes, where their dense root systems help secure and protect the soil so that it’s less likely to become detached.
Is it good to cut trees?
Cutting trees provides for regeneration , improved habitat for many species, maintains forest health, and helps us shape forests for the future.
What happens after straight trees are cut down?
What happens after straight trees are cut down? Once a tree is cut down, the trunk is chipped into mulch and hauled away, or cut into smaller logs or blocks for other purposes , but the roots remain in the ground. Without leaves, the cut tree cannot produce food for the growth of its roots.
Can we live without trees?
Without trees, we all die . Besides providing oxygen for us to breathe, trees make life on earth sustainable. ... Trees affect everything from the air we breathe to the rain that falls from the sky. Without a robust population of trees, we die and so does our planet.
