Weakened links portend disaster
To the editor,
Is it extreme arrogance or willful ignorance that allows humanity to believe we can do anything we want and not suffer the consequences?
Humans sit atop a food chain that begins with amoeba and evolves through many and varied life forms that contribute to our sustenance.
Recently released studies show a drastic reduction in the insect populations of the world. Although we generally dislike insects, they represent a critical link in the food chain. Most of this loss of insect life is directly attributable to human actions.
Overfishing has driven some food fish to near extinction. Corals, which provide both habitat and food for many fish, are dying off at alarming rates. Warming oceans are changing conditions necessary for the survival of many species.
Pollution of oceans is further limiting the survivability of even more species. Industrial wastes carelessly dumped into oceans as well as soil erosion and the run off of agricultural chemicals are creating large dead zones.
Petroleum products supply a major link in the modern food chain. Fuels, fertilizers and pesticides, all made from petroleum, are integral parts of modern agriculture. Due to much wasteful consumption, our petroleum supplies are being depleted at a rapid rate. Even if supplies could be maintained, the effects on climate would bring about disaster on its own.
Humans have been acting as if we are separate from the natural world. Although we have become the dominant species, and the most destructive, we remain tied to nature and natural resources. Our world is a finite system. We cannot draw down resources on an endless basis without incurring severe consequences.
The scientific community is nearly unanimous in predicting ecological collapse if we continue on our current path. This is not something that might occur in future centuries or millennia. The damage is so severe and widespread that virtually everything we count as normal could cease to be within the life spans of people living today.
Will we use our large brains to lead us to a safer path or will we put our faith in a “just in the nick of time,” Hollywood-style, miracle? Do we see lemmings when we look in our mirrors?
