Today an
article appeared in Times of India about pollution of river due to discharge of effluents from dyeing units and resultant loss of crops, barren fields and loss of livelihood to those dependent of agriculture. Toxic discharges in Noyyal river by dyeing units in Tirupur caused the agricultural field to become barren as toxic water can not be used for cultivation and farm works. A case in the court by those who lost there fertile lands lead to closure of the units which do not have effluent treatment plants (ETP) and because of this even the workers in these factories also lost their jobs.
Business is done to get profit. But, profit making is not at the cost of endangering eco system. ETP must be set up to treat the effluents so that no harmful substances enter into rivers or ground water. One can't say ETPs are costly and affects their business. They should see that it affects health of others in the area including themselves.
Earlier, similar situation was there in another place where tanning industry growth led to contamination of ground water. This made government to take stern action on pollutants to treat or shut policy.
