I am not sure if there are "the ten reasons." There might be many more than ten. I would submit that one primary reason is for ecological awareness. In my mind, the disruption of photosynthesis is one compelling reason why forests must be protected. As we give up carbon dioxide and plants take that a respired oxygen, removing forests decreases the output of oxygen, but at the same time releases the stored up carbon dioxide which serves to increase the temperature, as carbon is a heavy gas that traps. The shelter use of the forest for animals and humans is another reason why preserving them is essential. The issue of erosion, landslides, and flooding is another reality from removing the forests because the composition of the forests held and binds the soil to one location and removing that releases and unsettles that much more soil. The larger issue present would be that if forests are not protected allowing economic interests to reign, at what point is economic growth curtailed for larger issues? If ecology is sacrificed today, then tomorrow's victim could be communities of people and consumer rights. A reason to protect the forest might be to draw a line to indicate that this is the boundary where economic interests have to be integrated into other concerns.
1. Forest provides the greatest amount of oxygen, so about 2 / 3 of oxygen consumed by humans, animals, microorganisms, industry, agriculture, is taken from the atmosphere,where it's supplied by trees and shrubs (vegetation).
2. Absorbs a significant amount of CO2 (greenhouse gas), helping reduce pollution and having a positive impact on the environment.
3. Set the ground, preventing landslides and erosion caused by rain or wind.
4. Filter water from rainfall, by it's flow through the layers of moss and dead leaves, providing a clear and clean water.
5. Greatly reduces the size of floods, when torrential rains are falling, retaining large quantities of water in the canopy and litter and disposing it gradually.
6. Is an organic complex which houses many species of plants and animals, many of which being endangered, due to adaptation to specific conditions there.
7. It is a still little exploited source of medicines and natural remedies.
8. It has an aesthetic impact, forest landscapes being preferred to land occupied by crops or other human amenities.
9. It is considered a place of recreation, with therapeutic recognized effects.
10. It is of great importance for education - scientific, both for us and for future generations.
The forests are an integral component in the function of life. 1-Tress provide much needed Oxygen and serve as filters for gases that are toxic to humans. 2-Certain plants only exist in the forests. The plants are vital elements for medicines and consumption for certain species. 3-Forests are necessary to serve as habitats for wildlife. Without their existence many species will become extinct. 4- Removal of forests results in landslides, topsoil eradication, and changes the general use of the land. 5- Nutrients are destroyed when forests are cut down. Nutrients provide minerals and necessary nutrients to animals and plants. 6- The forest is a vast resource for wood supply for making furniture, building homes, and serves to provide fuel. 7-Climate changes can occur as a result of deforestation. 8-Forests are necessary for quality of life on a global scale. 9-Cultural destruction occurs as people who normally reside in the forests are forced to move elsewhere leaving behind their culture and ways of survival. 10-Prevents further exploration of cures for diseases such as cancer, etc., due to the lack of additional plants to study.
