It causes floods because all the trees are gone, leaving a clear, easy to navigate path for which water can flow.
When tree cover is removed the soil is far more exposed to the elements of wind and water that cause erosion and flooding. Further, the trees are no longer there to absorb the water.
Deforestation leads to reduced amounts of rainfall because forests are a major source of water vapor and moisture which helps to create rain clouds. Having less trees means more carbon dioxide which means there is more carbon dioxide to trap heat and less rain clouds.
Low rainfall or no rainfall leads to failure of crops .
High intensity rainfall can cause or lead to flooding because its allot of rainfall in a short amount of time meaning there wont be time for much of the rain to be infiltrate into the soils which leads to increased surface runoffs which increases the discharge in the river leading to floods.
The clearing of Forrest and expiation of roads can lead to deforestation.
Growing trees remove the greenhouse gas carbon dioxide (CO2) from the atmosphere, so deforestation means less CO2 is removed.Deforestation means that a lot of timber scraps are left to rot on the forest floor. Rotting timber releases either CO2 or methane, both greenhouse gases.Deforestation leaves large areas of land unprotected from floods and rainfall which can remove topsoil and small vegetation. This vegetation no longer removes CO2 from the air, but instead rots.
Rainfall leads to freshwater.
Large amounts of rain.
Deforestation and overgrazing are two common adverse effects of the human population on the environment. Deforestation and overgrazing leaves behind dry land and leads to desertification.
The main one... human greed for wood !
Deforestation is difficult to control as trees are being cut down and thus we are cutting homes of animals & birds to fulfil our needs and it leads to many problems. It causes soil erosion, floods and landslides. There is very less oxygen in the air to breathe birds & animals homes are lost when forests are cut and thus trees should be planted more.
Forests have tree's that give us oxygen and if we cut them down we will get rid of a major percentage of our oxygen plus deforestation leads to an increase of deserts.
