Many hardships are faced to people living near coastal regions
some of them are
1. radiation and its effect in genes.
2. polluted water
3.polluted air
the suggestion is to locate industries in less populated areas so that the effects will be less.
The problems faced are:
the water bodies which they use will be contaminated 
they might get respiratory problems because of pollution generated by industry.
they might get other skin problems and etc.

the precautions are:
they should change their place.
or the industries should plant on a less populated area.

because less causes, less harms.

thank you......
