Out of all the 18 species of penguins on Earth, 13 of them are threatened or endangered. The New Zealand erect-crested penguins have lost 70% of there population and the Galapagos penguins have a 30% chance of going extinct in this century. One big incident could rid the world of a penguin species.
There are multiple reasons why the are becoming so rare. Some are pollution, human appropriation of habitats. Also fishers catch them in their nets, and take all of the fish so more penguins die of starvation. Oil dumping and algae blooms are helping to cause this. Most of all, temperature change is the cause of the penguins coming closer to extinction.
Temperature change isn't just hurting penguins, it's altering sea ice and diminishing the krill population which is the base of many animals that live in the tundra. This is just a little of what is happening in the ocean though. A major reverse of how humans consume may be necessary in the near future.
Critical thinking question:
Can we save the penguins by consuming less?
