All species live within their niches, which are always primarily energy niches, in which an organism can obtain enough energy and preserve it for long enough to produce viable offspring. There are usually energy tradeoffs; efficiency could be sacrificed for rate of ingestion, so that efficiency was reduced but input was increased enough so that the increased cost of obtaining it was worthwhile, such as with . The primary measure of an organism’s success is its energy surplus, which is related to resilience. As an example, today a trout can live in a fast-moving current where food quickly arrives, which is efficient from an input perspective, but the energy spent swimming to maintain a presence in the current reduces the net energy surplus. A slower stream will provide less food per unit of time, but it also takes less energy to live there. In trout studies, the dominant trout will live where the optimal energy tradeoff exists, which leads to the greatest energy surplus. Less dominant trout will be pushed into the faster water, and the least competitive trout will be pushed into calm water and slowly starve. No species will last for long if it does not have a high enough energy surplus so that it can survive the vagaries of existence. The energy surplus issue has not been emphasized in biology during the past century, as the “” of a species has been emphasized, but it is the variable for understanding species fitness.
Even the from the shadows readily see how their game of chicken with Earth may turn out. Their more extreme members advocate terraforming Mars as their ultimate survival enclave if their games of power and control make Earth uninhabitable. But the saner members, who may now be a , favor the dissemination of those sequestered technologies. I am nearly certain that members of that disenchanted faction are those who gave my close friend an and who would quietly . They may also be subtly supporting my current efforts, of which this essay comprises a key component, but I have not heard from them and am not counting on them to save the day or help my efforts garner success. It is time for humanity to reach the level of collective sentience and integrity required to manifest humanity’s , which will initiate the Free Energy Epoch. Humanity can then live, for the first time, in an epoch of true and sustainable abundance. It could also halt the and humanity could turn Earth into something resembling heaven. With the Fifth Epochal Event, humanity will become a space-faring species, and a future will beckon that nobody on Earth today can truly imagine, just as nobody on Earth could predict how the previous Epochal Events transformed the human journey (, , , ).
The Coming Food Crisis :: essays research papers
The twin ideas of efficiency and resilience are important. Efficiency is about getting more for less, particularly energy. Although aerobic respiration’s energy efficiency allowed for to develop, they end up creating interactions and dependencies, and the entire structure can lose its resilience when compared to simpler systems. Remove one part of the food chain and the entire ecosystem can collapse, and it can be part of the chain, from top to bottom. Making systems more efficient, as the last bits of energy are wrung from the system, reduces their resilience to the real world’s surprises. That dynamic is probably a key contributing factor of mass extinctions during the eon of complex life. Modern ecosystems studies are making the connections clear and are being applied to the dynamics of human civilizations; work has been seminal in this regard. Complex ecosystems pass through of exploitation, conservation, release, and reorganization, and three dimensions of interaction are involved: potential, connectedness, and resilience. In general, simple systems are more stable than complex ones, which is another reason why any , if there were any, would have been far less cataclysmic than those of complex life.
