Charles Anderson:  Discovers Dragonflies that Cross Oceans

In this TED talk video, Charles Anderson, who is a marine biologist, talks about how he discovers a type of dragonfly in Maldives. He notices a special attribute that it carries. The Globe Skimmer is the type of dragonfly that has the longest migration of any insect.

Anderson says that the globe Skimmer’s long migration is due thanks to the wind currents of the Indian Ocean. Since they can only breed in fresh waster the population of the Globe Skimmers are great in number there in India. However, I think that you won’t see much of them in the western hemisphere because of various reasons.

First off, how will the Globe Skimmer be able to adapt to the temperature of the Western Hemisphere without dying in the process of migration? Secondly, I believe that pollution would contaminate the water to where there would not be any freshwater for the Globe Skimmer to reproduce. The main thing is it has to have freshwater. Lastly, where there is human growth population, there is voluminous industrialization which can cause a problem for the Globe Skimmer, due to waste and chemicals.

I highly respect Charles Anderson for his dedication to life that is alive on Earth before us. If more people could be more aware and involved, then nature could be preserved for generations in the future to see. Stories like those of the Amur Falcon and its death would less likely occur.

Most importantly, the extinction of animals would decrease.
