This is a criticism course aimed at practices that are often thought of as simply technical, ecological or preservation issues. Many thousands of ponds are being dredged in this country every year. Most of these ponds are products of rivers that have been dammed in order to build roads and developments through them. The river then becomes a series of ponds connected by culverts. Since it is no longer a river it is unable to flush and move sediments as it normally would.
Sediment builds up and the ponds begin to follow the natural evolution of a wetland-to become land.
