In the Early 1900’s the world agreed that whale meat was no longer needed to sustain the world’s population due to advancement of agriculture and farming technology.   The world encouraged The League of Nations to do something about stopping whaling because people felt that whales were being exploited due to advancement in whaling technology and they may become extinct.

 In 1986 the International Whaling Commission put a ban on commercial whaling, known as the Commercial Whaling Moratorium.   Some countries (Norway and Iceland) chose to reject this ban and continue to hunt whales commercially.   Some countries and populations use loopholes to avoid this.  

Japan uses the loophole and claims that they are performing “scientific research’ or continue the act because of tradition.   Japan however has produced minimal research findings.   Sources, such as the Sea Sharp’s show that Japan is actually using whaling to profit by selling the meat in markets.   Many activist groups, such as the Sea Shepard’s try to stop the Japanese from Commercial Whaling by using direct-action tactics. More can be found on their website: https://www.seashepherd.org/whales/

Due to Japans and other countries mass hunting of whales these gentle giants are being over-exploited (especially baleen whales) and are facing extinction.   Japan vowed in 2014 “to resume whaling for science’.    The theory is that whales will become extinct if they continue to be exploited and not properly managed.   World Wildlife Fund states that Commercial Whaling is one of the three major threats to these whales.

Guppies Adapting to Oil Pollution?

Scientist from McGill University believed that they had discovered   guppies that  could adapt to heavily oil-polluted oil environments in Trinidad.

What these scientist actually found was these guppies are not adapting to their environment. The scientist were surprised to find that their assumptions were wrong because the guppies seemed to be surviving just fine and are known to adapt  quickly.

The world’s ecosystem is changing quickly due to high stress that mankind is putting on the environment. If fish were able to adapt or survive in water that is highly polluted by oil it would be very beneficial.

The guppies didn’t adapt but  are instead “running away” from their competitors and predators.  The guppies  can survive in the oil-polluted environment much better than their predators and competition.
