Ocean Plastic Pollution
A World Threat
MILLION TONS OF PLASTIC ARE SPILLED IN OCEANS EACH YEAR
MARINE MAMMALS KILLED EVERY YEAR
MARINE SPECIES ALREADY
COUNTRIES GENERATE 50% OF OCEANIC PLASTIC POLLUTION
On-shore waste management
The main reasons for this pollution are the non-management of plastic waste in the littoral and fluvial zone and, to a lesser extent, the fishing and maritime activities. At this rate, by 2050, when the world’s population will approach 10 billion, there will be as many tonnes of plastics in the ocean as tons of fish (Helen MacArthur Foundation).
Collect macro-waste as soon as possible
A necessity to prevent the plastics degrade and become nano-waste, invisible to the naked eye, which are then directly assimilated by the marine micro-organisms which constitute the beginning of the marine food chain. Hard plastics decompose in oceans, releasing endocrine disruptor BPA.
75% of marine plastics flow
The remaining 25% drift in the ocean currents. They can, in part, return to the coast a few hundred or thousands of kilometers away. But the greater part will continue to drift and fragment at the whim of the oceanic forces, and turn into micro waste (> 5mm) and then nano waste.
Production of plastic waste
320 Million tonnes / year, 1 billion tonnes in 2050. Most of the plastic waste dumped by rivers annually into the oceans would come mainly from ten rivers or estuaries and coastal areas, with aggravating climatic phenomena in some areas (monsoon, cyclones, tsunamis, floods, …).
on human health (Sterility, hormonal disturbances, growth disorders …)
and economic activity (degradation of coastal tourism activity, destruction of fisheries resources).
