We've all been stunned by images showing the dramatic retreat of mountain glaciers. Yet few of us have given much thought to what happens next. Now the first study to look at how life invades soil immediately after mountain glaciers melt has an answer. Primitive bacteria step in to colonise the area, enrich the soil with nutrients, and even cement the ground, preventing landslides, say researchers who have studied the process in the Peruvian Andes.

Bali/Bangkok, 20 August 2008 - An innovative regional agreement is beginning to turn the tide for the 'ancient mariners' of the world's oceans. Marine turtles traverse the seas for thousands of kilometers, returning after decades to nest in the same area where they entered the world as tiny hatchlings.

We are in the midst of World Water Week. The 2008 theme is “Progress and Prospects on Water: For a Clean and Healthy World with Special Focus on Sanitation.” World Water Week is a international conference focused on collaboration and the promotion of work that advances environmental and humanitarian development. The United Nations proclaimed 2008 the International Year of Sanitation. With a focus on the Millennium Development Goals, the theme for World Water Week was chosen to draw attention to sanitation needs and the effect of poor sanitation worldwide. Goal seven - the goal of ensuring environmental sustainability- poses an enormous challenge, as do the sub goals, or target indicators. World Water Week highlights a target set by the MDG’s that calls for the reduction, by half, of the proportion of people without sustainable access to safe drinking water.
