1-Soil Erosion
It's easy to think of soil as compact and unmoving, but that isn't always accurate. Soil can be surprisingly loose, and it doesn't always stay in the same place. It can be washed away by rain or blown away by wind if it isn't properly anchored. What anchors the soil in place? The roots of plants, mostly. This is especially true of trees, which have roots large enough to anchor large swaths of soil. When humans clear large forests, soil erosion can become a serious problem. In some areas, eroding soil can lead to disastrous mudslides. Large amounts of soil can wash into local streams and rivers, clogging waterways and causing damage to hydroelectric structures and irrigation infrastructure. In certain areas, soil erosion issues caused by deforestation lead to farming problems and loss of reliable electric power.
2-Water Cycle Disruption
The water cycle is the process by which all water on earth is distributed. Water from Earth's oceans as well as from the surface of bodies of fresh water evaporates and condenses into clouds. Trees and other plants also extract groundwater and release that water into the atmosphere during photosynthesis. Clouds then produce rain, which becomes both groundwater and – eventually ocean water again.
However, when large numbers of trees are cut down, the water they usually extract, store and release into the atmosphere is no longer present. This means that cleared forests, which once had moist, fertile soil and plenty of rain become barren and dry. This kind of change in climate is called desertification. Such dry conditions can lead to an increased risk of fire on peatland and great loss of life for the plants and animals that once lived in the forest.
3-Greenhouse Gas Emissions
Greenhouse gases such as methane and carbon dioxide are gases that trap heat in Earth's atmosphere, leading to global climate change.
Fortunately, in addition to releasing oxygen and water into the atmosphere, trees also absorb carbon dioxide. While trees are still living, they function as efficient greenhouse gas filters.
The moment they are cut down, the carbon dioxide that was stored in their trunks and leaves is released into the atmosphere, further contributing to the buildup of greenhouse gases. After trees are removed from a large piece of land, the carbon dioxide in that area can no longer be absorbed as it was before.
