Symbioses knit together the fabric of life so that each action, each event, ripples through the fabric. The reproductive strategy followed by species, according to current theory, is to produce the most offspring, either sexually or asexually, that can survive to repeat the cycle and thus carry on the genetic story. No thought is given to how this will change the Earth or affect other creatures. Some creatures, such as the cod, use a strategy of having many offspring, each with a small chance of survival, while others such as African elephants, produce few offspring, each of which has a high chance of survival. While shortage of high-quality food, or disease, may feedback with an animal's or plant's hormonal system to limit reproduction, this may be simply an adaptation to use resources efficiently, to minimize reproductive waste and thereby to maximize the total number of offspring over a life span.
Nature unfolds forever without thought of what is fair.
In the unfolding, nature produces stunning beauty, grandeur, and diversity beyond our understanding. Enter humans, God's answer to the monkey wrench. Enter a species that modifies the ecosphere to produce food for itself, that combats disease, pestilence, drought, and sometimes even provides for humans less fortunate. Humans have spread across the entire planet, some would say like a metastasized cancer, destroying not only organisms, but the Earth's ability to create and support life. With time, they have evolved religions that place themselves apart from nature, above nature, favoured by the god of their making.
