Marine conservation
Marine pollution threaten resource
Nets and plastic debris endanger marine life
1. Plastics bags and bottles, gloves, floats,abandoned cargo
2. Marine mammals, seabirds, sea turtles
mistake floating plastic debrics for food and
can die of result ingesting material that they
cannot digest
