Soil erosion is the process of detachment of soil particles from the parent body or disturbance of the soil structure is known as soil erosion. Generally, soil erosion is called as the creeping death of the soil. Soil erosion is considered as negative soil pollution.
Causes of Soil Erosion:
Soil loss is maximum in the region with high population densities. Globally the present rate of soil erosion is over 2500 million tonnes/year. The chief causes of soil erosion are:
1. Land-use changes involving the destruction of forests and grasslands for expansion of agriculture and other commercial activities.
2. Overgrazing of pastures.
3. Fallowing of land for a longer duration.
4. Overuse of chemical fertilizers under intensive cultivation practices destroys the soil structure consequently the soil becomes susceptible to erosive forces.
5. Shifting cultivation by tribal population.
6. Continuous cultivation of the same crop.

Answer:
a) Migrant workers send monies as gifts to their relatives in their home countries, they increase the purchasing power of their relatives. More money equals more purchasing power. This purchasing power is futher magnified by the (in many cases) huge difference in purchasing power between the currency in the migrants home country and the country of temporary residence.
b) migrant workers send remittances in order maximize the added purchasing power afforded by the huge variances in exchange rate. These monies sometimes are gifted to family members to help them or for some other project to be executed on behalf of the migrant.
c) the money is either used by the recipient for their own purposes in the case of a gift or used for the execution of a project on behalf of the migrant. Projects may include setting up a business, building a house or purchasing a property etc.
