One of my favorite activities is people watching. When Jean and I take Amtrak to our various destinations, we love to sit in the terminals and watch the never ending panoply of human beings passing by. What an amazing biodiversity! So much variation, one has difficulty realizing that Homo sapiens is a single species.
One species we are, however, characterized by an almost infinite ability to change with the times, adapt, accommodate, get by, and respond to changing conditions through any mechanism other than evolution.
The most pressing problem I see now is that the majority of humans have distanced themselves from the "natural" world through a manufactured infrastructure. This has resulted in an almost complete disconnect from Nature, certainly a widespread lack of understanding of natural systems, ecology and interrelationships among humans and life in general. Here's a particularly egregious example of the outcome: Photos of beach tourists prove they are disconnected from Nature.
The result is a government and regulatory structure that responds to human centered demands at the expense of the natural world, with little regard for the effects of economic and human population growth on habitat, species, and resources for all life. We see it every day here in Santa Cruz, a supposedly "enlightened" populace, concerned with all manner of things "progressive" (sic), except, in almost every instance, things environmental. Supposed "environmental" excuses are trotted out to support most any project the Powers that Be wish to pursue, for their own economic and social reasons.
Thus, the once Greenbelt (no longer), Arana Gulch, was destroyed and turned into a playground for humans, based on the excuses of saving an endangered species and "getting people out of their cars and onto bicycles" (another lie, proven false). The Santa Cruz tarplant has now been extirpated from its only home, as a result of neglect and active destruction of its federally designated critical habitat. More cars now drive to Arana Gulch than ever before, and those who traveled by bicycle before the destruction continue to travel by bicycle on their preferred routes.
"Forcing" change resulted in a continuation and intensification of the status quo, and increased loss of natural habitat.
Ignorance of ecology and the natural world, coupled with a political system dominated by corporate interests and money has resulted in self-centered, destructive and ultimately suicidal societies that have reduced the biosphere to marginal viability, bordering on self-destruction.
The only way to stop or even slow down the destruction is to tear down the barriers to human understanding of Nature and natural systems. Get rid of cell phones and cell phone towers. Eschew automotive travel and get back on our feet, walking upright and free, not crammed into spam cans on our butts. Tear up half the roads and unstraighten the rest, unpave the parking lots and return them to native vegetation and animals. Round up the growth maniacs and send them off to an island in the South Pacific where they can build sand castles to their hearts content. Retire airlines and cargo planes and use the metal to build light and efficient railroads, linking villages and communities spread aesthetically across the continent. Stop city growth at an ecologically sound limit, and don't give in to development pressures to build more and more housing. Create incentives for residents to stay and live in place and stop moving on to "new" territory when they see the smoke from their neighbors' BBQ.
Get kids away from computers in school and out into the natural world. Let them lead their parents back to natural understanding of the real world, the natural world, our true home in the wild.
