PARIGI - Un pianeta distrutto. Questo erediteranno le future generazioni considerata la voracita’ con la quale oggi vengono consumate le risorse terrestri. L’ennesimo allarme e’ stato lanciato dall’Agenzia delle Nazioni Unite sull’ambiente (Unep) nel IV rapporto sulle prospettive globali della terra ‘GEO-4′ realizzato sulla base di dati raccolti negli ultimi 20 anni. Secondo gli esperti dopo le cinque estinzioni di massa verificatesi negli ultimi 450 milioni di anni, di cui l’ultima 65 milioni di anni fa, “la sesta e’ in corso e questa volta causata dall’uomo”.

Planet’s Tougher Problems Persist, UN Report Warns
Nairobi/New York, 25 October:The United Nations Environment Programme says that major threats to the planet such as climate change, the rate of extinction of species, and the challenge of feeding a growing population are among the many that remain unresolved, and all of them put humanity at risk.
The warning comes in UNEP’s Global Environment Outlook: environment for development (GEO-4) report published 20 years after the World Commission on Environment and Development (the Brundtland Commission) produced its seminal report, Our Common Future.
GEO-4, the latest in UNEP’s series of flagship reports, assesses the current state of the global atmosphere, land, water and biodiversity, describes the changes since 1987, and identifies priorities for action. GEO-4 is the most comprehensive UN report on the environment, prepared by about 390 experts and reviewed by more than 1 000 others across the world.
It salutes the world’s progress in tackling some relatively straightforward problems, with the environment now much closer to mainstream politics everywhere. But despite these advances, there remain the harder-to-manage issues, the “persistent” problems. Here, GEO-4 says: “There are no major issues raised in Our Common Future for which the foreseeable trends are favourable.”
Failure to address these persistent problems, UNEP says, may undo all the achievements so far on the simpler issues, and may threaten humanity’s survival. But it insists: “The objective is not to present a dark and gloomy scenario, but an urgent call for action.”
Achim Steiner, UN Under-Secretary General and UNEP Executive Director, said: “The international community’s response to the Brundtland Commission has in some cases been courageous and inspiring. But all too often it has been slow and at a pace and scale that fails to respond to or recognize the magnitude of the challenges facing the people and the environment of the planet”.
“Over the past 20 years, the international community has cut, by 95 per cent, the production of ozone-layer damaging chemicals; created a greenhouse gas emission reduction treaty along with innovative carbon trading and carbon offset markets; supported a rise in terrestrial protected areas to cover roughly 12 per cent of the Earth and devised numerous important instruments covering issues from biodiversity and desertification to the trade in hazardous wastes and living modified organisms,” he added.
