Finding/preserving the world of Nemo

 

Do you remember the cartoon “Finding Nemo” produced by Pixar? The sky-blue ocean, bloody red corals, violet mysterious jellyfish and evil sharks were essential attributes of “Nemo”. We all know how a sawfish looks like but have you ever asked yourself why a sawfish does has chainsaw instead of the nose. In the cartoon created basically for kids sawfish is fighting with its “rostrum” but do they do that in real world? The article “How the sawfish wields its saw… like a swordsman” taken from Discover magazine exhaustively answers this question. In fact, saws are both trackers and weapons. Because of small pores that sense the electrical field around living organisms, the saw can detect the movement and attack. Some sawfish can cut their victims in half. Good thing about the cartoon- it does not misrepresent the natural world: the methods of attacking sawfish are realistic. The article is worth exploring for people who were ever interested in sharks and their behavior; it contains biological and evolutionary information about this type of species and their position in the food chain. My personal conclusion from what I’ve read is that sawfish becoming extinct and the goal of scientists to preserve and to explore those animals. Otherwise, the “Finding Nemo” will be only a beautiful cartoon that we will show to our grandchildren saying: “And that is how the ocean used to be long time ago…”

    But should it really be our role to preserve nature by rescuing endangered species, relocating them, etc? The likes of Ben Harrison (https://uw20sciencemediaandculture.wordpress.com/2012/03/05/a-new-breed-of-strawberries-the-purple-wonder/#comments), after all, would say that nature is fine the way it is and that Mother Earth can fend for herself. If nature is a regulatory force, moving of its own volition to replenish, eliminate, and give rise to different species, is it really our role as humans to step into that role?

    Of course, in the most unconventional, irreverent, and speciesistic (http://en.wikipedia.org/wiki/Speciesism) manner possible, I say yes! Our dominion of the earth (in the least religious sense possible) and our capability alone entitle us to develop this sort of technology and to make the earth more suitable for our survival, if only for our aesthetic pleasure. And personally, I don’t think Mother Earth minds.
