the entry into the dams and ocean of chemicals, particles, industrial, agricultural and residential waste, or the spread of invasive organisms.Most sources of marine pollution are land based. The pollution often comes from nonpoint sources such as agricultural runoff and wind blown debris. Many potentially toxic chemicals adhere to tiny particles which arethen taken up by plankton and benthos animals, most of which are either deposit or filter feeders. In this way, the toxins are concentrated upward within ocean food chains. Many particles combine chemically in a manner highly depletive of oxygen, causing estuaries to become anoxic.When pesticides areincorporated into the marine ecosystem, they quickly become absorbed into marine food webs. Once in the food webs, these pesticides can cause mutations, as well as diseases, which can be harmful to humans as well as the entire food web.Cocerning the problems related to the marine wastes in the dams and seas and oceans throughout the world.Also Cocerning the littoral zones contaminated with the suspended particles and flootingwastes detected in many ports and coasts which not only leave the water dirtty and polluted but also jeopardize the organisms living there moreover because of the lack. Of any department engaged in collecting such wastes and pollutants also due to the simplicity of the evacuation of wastes into the sea .the costal environments alog with the ecosystems in which the existing organisms live are increasingly exposed to the invasion of some short term and long term deleterious hazards. Here we are intended to represent a system which is designed to collect the wastes flooting over the coastal waters and environments in a very simple manner.
