Drought is the reason for Debt to farmers, it happens when his hopes on nature is foolish and realizes that even the nature fool him with the unpredictable climatic changes.
The whole world depends on agriculture, agriculture is a profession acquired from nature. Our ancestors survived with agriculture and cattle rearing and still it is continuing with lot of changes. These changes are due to unpredictable climatic conditions, loss of fertility in soil, heavy rains, lack of proper economic management and due to uncontrolled pests, etc.
Some parts of the world, there are innocent and intelligent people who are still practicing the agriculture, they are called farmers. Farmers are innocent, because they believe in climate/seasons and they are intelligent, because they know one can only survive with agriculture and its products.
