Okay, I'll assume either negligence or innocence for the OP; but one important point is: Is there a lack of industrial zoned land in that region? Why didn't you buy or lease an industrial area to build whatever you are going to build.

Where I live, industrial lands run at 5-10 times the price of an agricultural land. So someone might justify going through the lengthy process (and bribe officials along the way) because he is going to profit at the end of it. At the detriment of people living or running their farms nearby.

My guess is that many people here are sympathetic because they didn't have their lives ruined by someone opening up a manufacturing unit next to their homes.
