Why do we need to clean up our fishing nets?

“The fresher the net, the easier it is to remove it from the bottom of the ocean,” Hamza said. NOAA also recommends affordable reception facilities for the nets because fishermen often dump gear into the ocean to avoid high disposal costs. “We have a beautiful natural resource and we are not taking care of it.
