The impact of deforestation from. The amount of forest decline. Inevitably cause physical changes and affects biological factors. Affecting soil, water, air, wildlife habitat more. Because both the resource and the environment are related, directly or indirectly, in no way contributes to the ecological balance of nature. Deforestation has caused an impact in various fields. As follows: 1. Soil Resources 1.1 erosion of soil. Normal flora of trees, shrubs and weeds, not all parts of the role. To help block the rains, the ground directly. Resistance to water runoff. Reduces the speed of the water Soil erosion is severe. Losing ground to rise 1.2 lack of fertile soil. Ground without weeds or forest cover. The soil by rain or wind will blow them up a lot, especially surface soil 2. Water Resources 2.1 floods in the rainy season, any action that disrupts the soil, such as deforestation, forest fires, haul wood surface. Tight clay The pore size decreases. Water seepage through soil surface decreased. Causing surface water runoff and drainage catch up. It turned into a flood in the lower area has more or less 2.2 , the drought in the dry season. The clearing forest destruction over a wide area, making the area a large timber incoherent cause evaporation of water from the surface soil. But water seepage through the surface low. Soil absorb and retain water in the soil, making it less feed streams with little or no coolant. Dry Creek is knitted Drought and water shortages to appear in late 2534 - 2536 and the year 2535 - 2537 and the year 2536 is a campaign about the occurrence of water shortages widely by asking everyone to conserve water with questions. Suggestions on how to use water in all its forms. To reduce the loss of water to the consumer. Consumers 2.3 deteriorate water quality The physical, chemical and biological water quality are inferior. If changes Or destroying forest areas The contamination of the sediments carried by water runoff through the soil or in other forms also suppress weeds or organic. In the course of your water. Causing contamination and a build up of dirt on the water, more or less, and likely much more. This is doubly different from upstream areas with forest cover. Good quality water is flowing Regularly and have enough volume can not be applied to consumer. Sediment in the water or into the sea to make a couple of muddy water in the state. The light from the sun, which is important in the light can not shine possible. Impede the process of photosynthesis of aquatic plants. The impact of fishing on indirect 3. The Economic and Social 3.1 Wood is expensive. The survey found that demand for wood in the country and not enough to meet demand. Those who want to use it illegally cut timber. When there is more demand Prices are always expensive and therefore cause a new career was illegally cut trees to sell 3.2 migration. Due to forest destruction Soil fertility, or lack of rain, with the resulting soil erosion from deforested areas. Fanning household items And the destruction of human life Prepare catch The migration to the new resident has occurred. The old place is not safe for the existence of the events in the south. The areas in . Apple's actions . Phipun in . Khiri Wong's . Lan Saka district . Nakhon Si Thammarat. The drought that required immigrants to find work in another place 4. Politics 4.1 Closing the forest. It is the policy of the government has done to prevent the destruction of forests. Causing misunderstandings between the MPs said. The closed forest were illegally cut wood up 4.2 campaign, the area deforested for arable farmers. From the forests are destroyed or degraded condition. The advertising campaign of a candidate to be elected as MPs. Has pledged to the people of that. If you own a substitute and then tries to find a way to give people ownership of space to eat, when elected, is lobbying for the people have a right to self reneged This is a political problem nationally significant 4.3 must be purchased. Timber from overseas Although the original forest had been exploited in abundance have been destroyed. The trees will be utilized gone. But the demand for wood for various activities persist and multiply even more demand. One way is done Buying wood from abroad Make more money out of the country annually 5. urban environment / World 5.1 air pollution. Since the respiration of all living species will release carbon dioxide are so many trees or forest enough. These trees will absorb carbon dioxide in the daytime. Photosynthesis Or gas resulting from incomplete combustion such as carbon monoxide is absorbed by these plants. Polluted air, it will not happen 5.2 sewage. The less water in the dry season of creeks, streams and rivers, causing sewage or waste scattered. Because the concentration of contaminants in water. The discharge of waste or wastewater into public waters, it is unavoidable to do so. The sewage problems creek where the water flows slowly plains. Creatures die and become extinct. The lack of water supply Lack of irrigation water And lack of fresh water caused the sea Etc. 5.3 World Or Greenhouse ( Greenhouse. Effect) regular gas that accumulates in the atmosphere above the Earth's surface up to 25 kilometers. Have banded together into a shielded surface of our planet is warm enough to sustain life acts like the glass in a greenhouse or " Green House " was constructed to maintain the temperature of the plants inside the greenhouse to life. Address The gases allow heat from the sun to come through.
