. Effects of deforestation.
Greenhouse Gas Emissions
Gases such as methane and carbon dioxide trap heat in Earth’s atmosphere, leading change in climate. Trees absorb the carbon dioxide and release oxygen and water into the atmosphere and this contributes to global warming. Cutting carbon dioxide adds to the environment and then this lack of the tree creates an absorption deficit. Deforestation leads to the emission of greenhouse gas.
Soil Erosion
Cutting down on trees leads to clearance of forests and so soil erosion occurs. Exposure of the soil to the sun’s heat dries up the moisture inside the soil. Nutrients evaporate and it affects the bacteria that help to break down organic matter. Due to this, rain washes the soil surfaces and erosion takes place. Large amounts of soil wash into local streams and rivers and cause damage to hydroelectric structures and irrigation infrastructure.
