Figuratively speaking, a ginormous asteroid is hurtling to a cataclysmic rendezvous with earth, but we are not supposed to notice. The asteroid is the rising threat from environmental degradation. Evidence is accumulating that environmental degradation is becoming global.

We can either act responsibly by accepting the challenge or take refuge in denial and risk the consequences.

There is nothing new about climate change. It has been ongoing for as long as earth has had an atmosphere. Through change, nature produced an atmosphere supportive of life. We know for a fact that human activities can have adverse impacts on the air, water, and land resources. If these impacts become global, as independent scientists believe, life on earth might be at risk.

We're in a state of perpetual crisis

Moreover, environmental degradation can contribute to, and be worsened by, other changes that are not under our control. Presently humanity is challenged by three revolutions which collectively constitute a perpetual crisis: the technological revolution that is displacing humans in the production of goods and services, the volatility and instability of the global financial system, and environmental degradation. Our focus is on environmental degradation.

It's a matter of balance

The weight of the atmosphere, at 14.7 PSI, has remained relatively constant throughout much of earth's existence. What has varied is the makeup of the atmospheric gaseous mix. The mixes that existed prior to the current era would prove toxic to the contemporary biosphere. As the biosphere evolved over the hundreds of millions of years prior to the current era, the gaseous mix of the atmosphere and the biosphere came into perfect, or indeed as some might say, heavenly balance.

Indeed, our very existence as well as the existence of the biosphere depends on this balance. There is no question that human activities can affect this balance. Perhaps not enough that nature wouldn't eventually be able to reset the balance, but perhaps enough to end civilization before nature could correct the disturbance. While some are cavalierly dismissive, others have concluded that things are already so irreversibly out of balance that civilization as we know it will cease before the middle of this century.

Easter Island is an example of death by environmental degradation on a local level. When the island was first settled, it was covered by a forest. Soil analysis suggests that the natural environment was reasonably diverse and, absent human settlement, resilient enough to recover from natural disturbances that included volcanic eruptions. The humans that settled on Easter Island thrived until the population degraded the environment to the point that it could not support the population.

Tree removal was one of the activities that proved detrimental to the island's natural balance. As trees were removed, so too was the island's natural diversity and its ability to support human habitation. Many have wondered what Easter Islanders were thinking as they cut down the last tree.

Environmental degradation's role in the collapse of civilizations is well told in Jared Diamond's book, Collapse. At least two pre-Columbian empires fell to sudden environmental collapse. Environmental degradation even contributed to Rome's fall. Throughout history, empires and civilizations have collapsed once they degrade the environment below its capacity to carry the human footprint imposed on the environment.

Global warming introduces a difference. In the past environmental destruction was local or regional. But what is now underway appears to be global. It can take a long time to unbalance the biosphere, but once the line is crossed, collapse can be rapid and irreversible.

Global Warming a hoax?
