Sustaining Aquatic Biodiversity Section 1 & 2 - Page Text Content

FC: Sustaining Aquatic Biodiversity 2009

1: HIPPCO | H-habitat loss and degradation I-Invasive Species P-Population Growth P-Pollution C-Climate Change O-OverFishing

2: So Many Books, So Little Time | Habitat Loss and Degradation | -human activity is affecting aquatic habitats -fishing methods are destroying sea bottom habitats

4: Invasive Species | -these bioinvaders can cause an extinction of native species - they can disrupt ecosystem services Example: Lake Victoria has been invaded by Water Hyacinth

7: Population Growth & Pollution | -by 2020, 80% of the worlds population will live near the coasts -this population growth will destroy more aquatic habitats and increasing pollution -pollution from human activities: runoff, waste, toxic pollutants

8: Climate Change | -threatens aquatic biodiversity by causing sea levels to rise -this would destroy more coral reefs, drown many productive coastal wetlands and put the Louisiana coast under water

10: -causes a depletion in marine life - According to IUCN 71% of the worlds marine fish species face extinction | Overfishing

12: Fish Farming | Long Line fishing

13: Some of the Industrial Fishing methods include: - Fish Farming -Trawler Fishing -Drift-net fishing -Long-Line Fishing -and much more

14: How Can We Protect and Sustain Marine Biodiversity

16: It is hard to protect marine biodiversity because of: - human ecological footprint - Fish print -The damage is not visible -Humans view seas as inexhaustible

17: Only laws and treaties can help marine biodiversity.

18: Cetaceans are an order of mostly marine mammals between - feet and 100 ft. Toothed Whales are bite, and chew food Baleen Whales are filter feeders. Attached to their upper jaw is baleen which they use to filter plankton. Whales are killed easily partly because of their big size and need for air.

20: The NAture Conservancy promoted whale watching

21: Overharvesting drove the giant blue whale to the brink of biological extinction. IWC or International Whale Commission regulates whale industry by setting quotas.

22: Educating citizens about aquatic biodiversity could inspire communities to protect endangered water species.

24: The Leatherback turtle is the Largest sea turtle, and the only warm blooded. -Bottom trawlers are destroying the coral gardens that are the turtles feed ground. -pollution is also a threat to the turtles:they sometimes mistake plastic for jelly fish

26: Marine Sanctuaries Protect Ecosystems Species: - | -Foreign fishing vessel can take certain quotas shores of fishing within such zones called executive economic zones - High Seas are oceans outside of jurisdiction.

28: The purpose of the ecosystem approach is to protect and sustain whole marine ecosystems for current and future generations instead of focusing primarily om protecting individual species.

29: Protecting Marine Biodiversity Requires Commitment From Individuals and Communities. | Over all aim of such programs is for fishers business owners, scientist etc. to identify shared problems and goals in their use in marine resources
