A Question of Balance

Balance....or imbalance. Words that bring to mind the question of our impact on the earth. Is our exploitation of forests, fisheries and the land killing the biosphere? When will the daily extinction of species be cause for concern? Has the buffer of the atmosphere and ocean been overwhelmed by our pollutants? Is our population beyond that which the earth can support? Time passes and politicians continue to bicker. When will we learn to exist in balance with our planet, for imbalance is not an option.
