In addition to the previous statement if these top of the food chain predators were to be removed from their ecosystems‚ the health and balance of these ecosystems would become shattered and disturbed‚ with nobody to maintain

October 24‚ 2013 Shark Finning is Inhumane Every year millions of sharks die a slow and immoral death from fishermen stripping them of their fins. These fish are taken out of the ocean and then stripped of their fins where their carcasses are then thrown back into the sea to either starve to death‚ be eaten by other predators‚ or drown because of the lack of constant movement their gills cannot extract oxygen from the water which is not only cruel but unorthodox.

Who is involved in shark finning‚ and where? Finning occurs worldwide and is most common in high seas fisheries‚ hundreds of miles out to sea. Oceanic fishing fleets target valuable fish such as tuna‚ using thousands of baited hooks on miles of long-line‚ and freezing their catch onboard. Unfortunately‚ long-liners often catch several times as many sharks than they do tuna. Until relatively recently‚ this shark ’bycatch’ was considered a nuisance‚ and sharks were cut loose and allowed to swim away

I attempted to see what organ was connected to what and learn how squid differ from the human organ structure. I ’ve learned that the structure
