Answer:
losers cuz they live in the cold
Answer and Explanation:
supply rural people with long-term employment, adequate income and decent living and working conditions; maintain, if necessary after rehabilitation, the productive capacity of natural resources; and. mitigate the agricultural sector's vulnerability to hostile natural and socio-economic factors and other hazards.
Explanation:
UV (ultraviolet) levels are high in the areas of high altitudes. Tibetan plateau being the highest plateau of the world is more exposed to the UV radiations as the atmosphere gets thinner in the areas of higher altitude. So it can not filter the maximum of ultraviolet radiations. Tibetan plateau is on 4,500 meters height and the UV level increase by 10-12% upon every 1000 meter elevation.
However in those areas having the constant cloud cover like in Congo Basin the UV level is low as the clouds scatter the most of the UV radiations and they particularly stop the UV-B radiations. Thats why the cloudy areas have less UV level then the areas having a cloudless clear sky.
The map of the United States that is representing the soil erosion, shows us a trend that the soil erosion is the biggest in the areas where there is the most agricultural activity in the country, mostly the Midwest, the southern part, and the lowlands east of the Appalachians.
It is no wonder that the areas where there is the highest agricultural activity have the highest wind and water erosion. What is now agricultural land, in the past had a natural protection of wild plants, but now it doesn't.
The constant plowing of the soil results in making the soil much more loose several times in a year, sot he wind is able to pick up particles easily, and the water is able to easily move the top layers.
The heavy usage of pesticides, herbicides, fungicides, and artificial fertilizers are also making the soil very loos, so the erosion has big effect.
Depending on the irrigation method, it can have a big effect, especially if it is irrigation through ditches, as the water will be pushing from one side and moving toward the other side, moving the top soil with it.
