Fish are becoming infertile in Laguna de Bay
Industrial and household wastes dumped into the Laguna de Bay are not only killing the lake but are making the fish impotent.
Agriculture Magazine, citing Dr. Joseph Mercola (www.mercola.com) said untreated wastes dumped into the bay are being blamed for the abnormalities in the reproductive system of the male common carp.
The report said the abnormalities include testicular degeneration that could lead to infertility and threaten the sustainability of the species.
Dr. Michelle Grace Paraso, associate professor at the University of the Philippines Los Banos – College of Veterinary Medicine, said among the pollutants that threaten fish in Laguna de Bay are xenoestrogens, which disrupt the endocrine system.
Exposure to xenoestrogen is linked to low sperm count, precocious puberty and increased incidence of breast cancer among humans, and reproductive abnormalities and population decline among animals.
Xenoestrogens are found in more than 70,000 chemicals used in fertilizers, herbicides and fungicides used by non-organic farmers.
