Why have many haitians left the countryside for the cities?

Many farmers decide to migrate from the countryside to cities in order to obtain better job opportunities. As the years have progressed, less farmers are needed to work on farms due to the advances in technology and industrialization. A job that once took 500 famers to do may now only take 50. Due to this major cut in workforce, many famers are left jobless and in debt. Cities are bigger and offer more room to grow and work, therefore, many farmers chose to move and find an alternative way to feed their families and create a better lifestyle for themselves.

no questions on whether they are allowed that right

explanation:

allergens: overstimulate the nerve system

neurotics: attack nerve cells

mutagens: damage or otherwise alter dna sequence

generators: cause defects during growth and development  

carcinogens: cause unchecked cell growth

i hope you get the idea according to me these are the effects that happened.
