As
the population is increasing globally, the need of food is
also rising. Basically the need of food is directly proportional to increase in
population.
Consequently, there is a great pressure on farmers to grow edible
products in huge amounts on a very large scale so that the demands could be
met.
Moreover, farmers don’t want to waste anything, a tractor pulls out every inch of the produce which maximizes the profits,
whereas when the work is done manually
there is a chance that something gets missed out or is damaged enough that it
becomes useless.
