New Delhi, Oct 27 - Major threats to the world 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 United Nations Environment Programme (UNEP) has warned.The warning comes in UNEP's Global Environment Outlook: environment for development (GEO-4) report released Friday.GEO-4 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 for which the foreseeable trends are favourable.'On the urgent issue of climate change, the report says the threat is now so urgent that large cuts in greenhouse gases by mid-century are needed. Negotiations are due to start in December on a treaty to replace the Kyoto Protocol, the international climate agreement that obligates countries to control anthropogenic greenhouse gas emissions.Although the protocol exempts all developing countries from emission reduction commitments, there is growing pressure on some rapidly industrialising countries -- now substantial emitters themselves -- to agree to emission reductions.GEO-4 says the world faces an overall crisis that includes climate change, extinction rates, hunger, problems driven by growing human numbers, the rising consumption of the rich and the desperation of the poor. The effects of this crisis are shown in decline of fish stocks, loss of fertile land through degradation or dwindling amount of fresh water available, for example.The report says climate change is a 'global priority', and the response to it demands political will and leadership. Yet UNEP finds 'a remarkable lack of urgency', and a 'woefully inadequate' global response.Several highly polluting countries have refused to ratify the Kyoto Protocol. GEO-4 says: 'Some industrial sectors that were unfavourable to the Protocol managed successfully to undermine the political will to ratify it.''Fundamental changes in social and economic structures, including lifestyle changes, are crucial if rapid progress is to be achieved,' the report points out.On the issue of water supply, GEO-4 warns that irrigation already takes about 70 percent of available water, yet the world will have to double food production by 2050. 'The escalating burden of water demand will become intolerable in water-scarce countries.'Water quality is declining too, polluted by microbial pathogens and excessive nutrients. Globally, contaminated water remains the greatest single cause of human disease and death.
