With one third of the Earth's surface is covered with forests it is no surprise that they are among the most notable storehouses of biological diversity on the planet.

The complex ecological relationships involving forests could allow humans to benefit from them in a variety of ways. However, a deeper understanding of these relationships is crucial for the development of effective, sustainable forest management and policy options. •Climate Change

It's nearly impossible to overstate the threat of climate change. Greenhouse gas emissions are rising more rapidly than predicted and consequently the world is warming more quickly. Global warming will have catastrophic effects such as accelerating sea level rise, droughts, floods, storms and heat waves. These will impact some of the world's poorest and most vulnerable people, disrupting food production, and threatening vitally important species, habitats and ecosystems. •Water

Oceans cover 71% of our planet’s surface and make up 95% of all the space available to life. Life began in the oceans, and...
