Drought during 2011 has caused many problems. First, the people lack clean water to either take a bath, wash clothes or drink. Consequently, the government has to spend more expenditure in social welfare. Second, many breeders do not find grass for their cattle, sheep and goats. As a result, their animals get thinner day after day due to lack of enough food. Third, many farmers who depend on rainfall can’t cultivate their land. Consequently, they do not get regular income from agribusiness. This also causes the farmer laborers to lose their jobs. Therefore, the poverty rate will increase this year. Finally, the drought has a great impact on the water reservoir: dams, lake, Canal. Their water levels go down even totally dry. All of those conditions are clearly due to the long drought in our country.

Why do animals get thinners?
