  10. 10. Statistics on the Effects of Ocean Pollution ▪ 300 Albatross chicks on Midway Island, 1600 km from the nearest land had plastic in its stomach. ▪ There are over 46,000 pieces of plastic floating in each square mile of ocean. This plastic contributes to the death of 100,000 marine mammals and two million sea birds yearly. ▪ As of mid-June, 2013, the oil spill has contributed to the death of 658 sea birds, 279 sea turtles, 36 sea mammals, and countless fish. ▪ 60 percent of a rare species of iguanas on the Galapagos Islands died after an oil spill off the coast of those islands in 2012.

  12. 12. Large Scale Solutions for Ocean Pollution ▪ Stricter government regulations on industry and manufacturing ▪ Renewable energy sources so off-shore drilling no longer needed ▪ Limit agricultural pesticides ▪ Proper sewage treatment ▪ Cut down on waste and contain landfills
  13. 13. Changes to Make at Home ▪ Carry a reusable shopping bag instead of plastic bags ▪ Store food in reusable containers instead of those you throw away ▪ Avoid products that come with excess packaging ▪ Don't litter ▪ Recycle ▪ Volunteer your time to clean up a beach if you live nearby ▪ Visit the beach, tourism improves coastal communities ▪ Donate to an organization that protects the ocean
