LONDON, Oct 17 (Reuters) - The Earth's natural resources like food, water and forests are being depleted at an alarming speed, causing hunger, conflict, social unrest and species extinction, experts at a climate and health conference in London warned on Monday.

Increased hunger due to food yield changes will lead to malnutrition; water scarcity will deteriorate hygiene; pollution will weaken immune systems; and displacement and social disorder due to conflicts over water and land will increase the spread of infectious diseases, they said.

The United Nations Economic and Social Council (ECOSOC) voted to establish a committee on global geospatial information management in order to enhance international dialogue and cooperation on spatial data infrastructures. The UN recognizes the benefits of geospatial information for application to humanitarian, peace and security, environmental and development challenges as well as to responses to climate change, natural disasters, pandemics, famines, population displacement, and food and economic crises.

GENEVA (AP) - For years, the world has been on the brink of wiping out polio, the deadly disease that can paralyze and kill children. At the World Health Organization's annual meeting of health ministers this week, experts are unveiling what they describe as a new strategy to get rid of the feared disease. But others say there is little new and that if this effort fails, there are serious questions about whether to continue the campaign should be raised. Some experts say eradicating polio is impossible and should be abandoned.
