Abstract: Shipping routes in the ocean are analogous to terrestrial roads, in that they are regularly used thoroughfares that concentrate the movement of vessels between multiple locations. We applied a terrestrial road ecology framework to examine the ecological
impacts of increased global shipping on “marine giants” (ie great whales, basking sharks [Cetorhinus maximus], and whale sharks
[Rhincodon typus]). This framework aided in identifying where such “marine roads” and marine giants are likely to interact and
the consequences of those interactions. We also reviewed known impacts of shipping routes on these species, and then applied the
road ecology framework to detect unknown and potentially threatening processes. In the marine environment, such a framework
can be used to incorporate knowledge of existing shipping impacts into management practices, thereby reducing the detrimental
effects of future expansion of shipping routes on marine giants.

    Just 15 of these mega-container ships produce as much CO2 as all of the autos on earth, but there are over 60 in service and 60,000 smaller ones. And what keeps this world destroying trade going? You, my friend, every time you shop at Made in China Walmart, or any other Big Box store. You, my fellow Americans and Europeans are killing these whales and increasing atmospheric CO2 by your “consumerism”. Don’t want to take responsibility? That’s OK, no other “consumer” does either. We should be so ashamed, but we’re not. We prefer to watch the gladiators of the NFL and play with our Chinese toys. Fortunately for Mother Earth (or The Good Lord, if you prefer), we are rapidly headed for extinction as a species, thanks to population density stress and all of our ever mounting “diseases of civilization”.
