From where is this to derive? Are we going to get into a largely self-contained loop wherein biofuel is used to run farm machinery to produce biofuel crops to create more biofuel to run the machinery? Hopefully, benefits will accrue beyond this limited availability despite that biofuels are considered not particularly energy efficient. Simultaneously, cultivation of its homogenous agriculture across the world is responsible for much slash and burn pollution. This in mind, ethanol futures expect to perform well as, one by one, rainforests are replaced by sweeping tracts of unvarying plant life.
 
Food woes further in mind, trawling vessels, also, pose a problem... While spanning in size up to 100 meters long, they can weigh as much as 3,000 tons apiece. With a staggering number of them in existence, global fleets, as of ten years ago, managed to dreg 15 million square kilometers on an annual basis.
 
Now the expanse covered is larger and their trawling depths can reach down to 900 meters, while often scraping huge areas and, simultaneously, rendering them practically devoid of life. On account of this and other highly successful forms of demolition, nine of the seventeen major ocean fisheries are in severe decline and four are commercially collapsed, according to UN sources. In consideration, one has to ask, how much longer will sea life continue to be available to plunder?
 
For now, though, approximately 200 million people (a huge portion of the world's population) derive their employment from the fishing industry, no fishing vessel owners want to cut back their take when others will not do so and seafood delivers more than half of world's animal protein eaten by people. At the same time, there is a constant demand for more.
 
Concurrently, half the world's turtles face extinction and, for some, it is due to lack of shrimp, a dietary mainstay for many kinds. (Over four million tons of shrimp are eaten per year by humans of which three fourth is wild capture, along with representing a multibillion dollar industry. Furthermore, its consumption is quickly rising around the world, so shrimp holds much appeal from a business standpoint.)
 
All considered, perhaps our problem is capitalism, itself, as it is just too hard to forego ever greater revenues in a aim to deliberately protect the environment and ensure that other species can simply stay alive in moderate quantities. Put another way, money in exchange for ever more greatly dismantling of the Earth is an irresistible temptation for far too many people. Of course, an almost exclusive focus on materialism and personal resource obtainment was bound to take place in a cultural climate that assigns relative individual worth based on fatuous status symbols, such as the cost of the car that one owns or the degree that one's partner exudes raw sensuality and other gender related traits. How unfortunate it is that this sort of mind set holds more appeal than any qualities with substantial value and depth, such as the degree that one is philanthropic, principled, compassionate or heroic.
 
Moreover, those in the economic top tier, definitely, garner the lion's share of resources and there is a pecking order. However, look at these terms: lion's share" and "pecking order." They seem to point to the notion that the trouble with our species maybe runs deeper than one in which capitalism is to blame for our wild successes as we advance against other member of our kind and other life forms to "hog it all." So, perhaps, as we continue our movement towards massive annihilation, we are more like many other life forms, after all. Maybe we are even like plain old bacteria in a pitre dish, a small set of organisms with a substantial, although fixed, supply of agar (food) and a limited, although ample, atmosphere created by a lid.
 
This comparison in mind, the ultimate result in the covered dish is predictable. The microorganisms either breed to the point that they run out of food or they, before that point, expire in their own waste gases, pollution in their atmospherically enclosed world. Either way, there is a lesson for humankind.
 
At the same time, the pecking order arrangement, relative to our voluminous population, all but ensures that nearly all individuals in the labor market, except for "the top dogs," are expendable based on whomever, with the right set of needed skills, can be obtained for the lowest wages. As dehumanizing as this is, it is, in fact, the reason that jobs disappear from the US to Mexico in that the latter's annual minimum wage is set at $1,557-1,658 International Dollars, a unit of monetary measurement corresponding to the purchasing power of the $ USD in the US at a fixed point in time. (It is, also, know as the Geary-Khamis dollar.) It is, likewise, the reason that these same jobs, eventually, disappear from Mexico to other countries, such as China, wherein annual income expectations are even lower. (In 2006, officials in Guangdong Province set minimum wage according to five classifications with the highest being comparable to approximately USD $0.60/ hour and the lowest being roughly USD $0.25/ hour. In other words, there is no way that Mexico workers, and especially not American ones, can reasonably compete in the global market.)
 
Perhaps then, competition and not predacious capitalism, per se, is to blame for the sweeping demise of other species taking place, large portions of first world economies going belly up and other tribulations, such as global warming, worsening. If so, it is likely that humans just can find their own balance and place in the natural scheme of things.
 
Perhaps we are just a little too arrogant, materialistic and anthropocentric in the smug delusion that we, God-like more than animal-like, are somehow above and superior to nature. Accordingly, many people believe that the planet and all its inhabitants were put here because "... God saith, 'Let Us make man in Our image, according to Our likeness, and let them rule over fish of the sea, and over fowl of the heavens, and over cattle, and over all the earth, and over every creeping thing that is creeping on the earth [5].'" 
 
Then again, possibly our problem is simply that too many of us cannot look at a spring fed lake in terms of its sheer beauty, but, see instead... an ideal location for a Coca-Cola plant, a bottled water source, the makings of a gigantic five star resort, a family oriented water park, a way to provide water to a huge hog farm that we will place on its shore after we tear down the surrounding forest for lumber or any number of other visions to negatively impact its natural state for personal gain. In other words, the end result, regardless of the way that it's achieved, involves the permanent disruption of the natural world and the construction of something manmade in its stead for the sake of immediate financial recompense.
 
This is, of course, the same sort of consideration that drives Special Economic Zone (SEZ) policies in India and China. In tandem, the military-industrial complex in many countries are all too willing to assist when powerful industrial conglomerates team up with governments to force mandated changes on small, disorganized populations to ensconce themselves in new locations for the sole purpose of controlling and using up local resources. Insightful descriptions of this sort of process and the ensuing struggle can be found at reference six [6].
