: The desert area is expanding at growing rates every year. So why don't we change all the desert areas to productive farmlands? I know this project requires a great sum of money, but it's worthy and essential. By doing this, there will be more food supply for the growing population.
I think to make desert into farmland is too expensive.
The area whose soil resources are used up changes into desert gradually.
Those areas are usually located in poor countries where people do not have money.
