While some species of dolphins in certain areas are being affected by bacterial infections and unusual deaths, there is no evidence of a worldwide extinction event. Only certain populations of some dolphin species have seen higher mortality, while others are stable. Possible causes for some localized die-offs include abnormal weather, toxic algae, pollution exposure, and loss of prey. Human impacts on oceans, like pollution, are negatively impacting dolphin populations around the world.

1. Dolphins are said to being dying, but is it the end of
their species?

2. No Dolphins are not going extinct.
"There is no evidence at this time to
indicate that such a worldwide, multi-species crash is
occurring," Randall Wells, director of the Sarasota
Dolphin Research Program said.

3. The Truth
 There is no world-wide die out of dolphins
 Bacterial Infection has been spreading
 Only certain species of the population have been hit
 The same species in other areas could be doing fine

4. Bottlenose Dolphins
 For example the bottlenose dolphin was hit hard in the
Gulf of Mexico year of 2010 before the oil spill in April.

5. What is Happening
 “No common infectious disease has been identified in
any of the current dolphin stranding events,” said
Barclay.
 These could wipe out families of dolphins effecting the
later generations population
 It is a SERIOUS concern to the dolphin research and
conservationist.

6. Reasoning Possible for this
Dilemma
 abnormal weather
 toxic algae blooms
 parasites
 pollution exposure
 loss of prey leading to starvation
 disorientation due to loud noises from ships and oil
exploration
 physical injury

7. The Ones Affected
 The Chinese river dolphin

8. Humans are at fault.
 “What isn't in doubt is that human impacts on the
ocean are hurting dolphins around the world.”
 Dolphins need the water and most people do not
realize what they are polluting the ocean.

9. STOP
POLLUTION!
