Choose all the scenarios below that would cause a decrease in the supply of labor in the agricultural industry.

a. More women are entering the workforce in all industries in the United States.

g. The government passed a new plan to provide government-funded health care for all workers in the agricultural industry.
h. New machinery is replacing workers in the harvesting of crops.

Explanation:

With workers getting older and being unable to be as productive as they used to be, they will have to drop out of industries that require physical strength including farming. This will therefore reduce people working in agriculture.

With global warming having made working in the fields much more harsh, people are avoiding careers that would keep them outdoors including farming which has led to a drop in the labor supply for agriculture.

A significant portion of workers in agriculture are immigrants so when immigration laws limit the number of immigrants coming in, labor supply in agriculture will reduce.

New machinery reduces the need for workers in agriculture so the more they are bought, the less workers are needed. This will therefore directly reduce the number of people working in agriculture.
