This is perhaps the greatest challenge. The vast majority of our species now live where all but they and a few human-dependent species remain. The rest have gone and gone for ever. The threat to habitat and to communities of wild species is actually from a relatively small proportion of the total human population, be it considered globally or at the local level. Notwithstanding this, the consumptive trends are encouraging this small element to decimate natural habitats to produce the needs, or perceived needs, of the growing markets.
Conservation is a responsibility of leaders.
Those of us who can afford to make policy, do so, on behalf of these who cannot. Many actions of responsible government are not necessarily popular with the people but through civic education and other means, people do learn to accept regulation of their lives and activities in some form. Nonetheless, I personally believe that in the area of species protection, we should concern ourselves with what is right as opposed to what may be easier, or popular in the short term. We need, as leaders, to lead and to be accountable for our leadership. Revenue sharing, decision sharing and similar well intended tactics will not be sustainable in those parts of the world where the general standard of living is declining and where there is a frightening increment to the cost of meeting basic human needs.
