I sometimes wonder if humans are the only species that actually live irresponsibly…
I am not making excuses for us, just thinking out loud. We should know better but…
I wonder about the various insects which seem to kill the trees and plants they need to survive. The voracious plagues of locusts we have heard and read about. They move on only after wiping out the flora in the area. Does it always recover or does it sometimes turn into a desert devoid of the plants it had sustained before?
I have heard of nematodes that reside in the saliva of beetles until they are introduced into a pine tree at which point they proceed to the root system and end up cutting off the nutrition supply to the tree, eventually killing it. That seems pretty irresponsible to me and yet we think of it as nature.
Then there are viruses and bacteria which kill their hosts…granted they go on to survive, even thrive, in the larger sense, but they are leaving a wake of destruction and death as they go about sustaining themselves. Are humans the same way?
I also wonder about extinctions in the past – those clearly unrelated to human intervention or natural disaster. Are there any cases where a species has devastated its environment to the point where it eliminates the source of sustenance and commits environmental suicide? I haven’t heard of any but it would be interesting to find out.
Again, I am not about to question the concept that humans are shaping the environment but I do question the extent of our blame when compared to nature itself.
If the Sahara was not a desert but a lush forest in the past – how did it happen to change? Well before humans had a chance to be involved? How much change to the climate has continental drift caused? If we believe that El Nino and El Nina modify our weather and those are based upon ocean currents, how would the currents have been different before the continents were in their current positions? The weather (climate) must be considerably changed by tectonics and, some would suggest, those changes make the changes imposed by human activity pale in comparison.
All that being said, we need to change what we can change and we must be more reasonable in our activities. Should we cut back on our lifestyles to use less energy? If we are a family of two, do we really need more than two bedrooms, living rooms with no one living in them, dining areas off the kitchen AND formal dining rooms? Do we really need the electronic toys we all feel we can’t live without – each consuming energy to operate, disposable batteries, and resources to make them out of plastic and metal? Should we reconsider our disposable society where we toss out repairable goods – meaning more in the landfill and more energy and resources consumed to make a replacement simply because we think it is cheaper - is it really if we consider the true impact on our environment?
All of these are things to consider but who among us wants to step up to the plate – before our neighbor?
