What's up on Planet Earth?
Here is a startling report by the UN about the state of the Global Environment. From poverty to climate change, pollution and access to clean water, we seem to be faced with an ever spiraling issue. In our view, it is vitally important to share information such as this so that we may know the extent of the problem facing us. In that way it gives us the chance to make individual as well as collective choices about our future such as becoming more self sustaining. That's why we share it with you here...

From the BBC News 24|Special Report
Globally human populations are growing, trade is increasing, and living standards are rising for many. But, according to the UN's latest Global Environment Outlook report, long-term problems including climate change, pollution, access to clean water, and the threat of mass extinctions are being met with "a remarkable lack of urgency".

CHANGING WORLD

Over the last 20 years, the human population has increased by a third, global trade has tripled, and per capita income has gone up by 40%. Annual emissions of the main greenhouse gas, carbon dioxide, have also increased by one third.

SHRINKING RESOURCES

As the human population grows it has reached the point, the UN says, "where the amount of resources needed to sustain it exceeds what is available".

BIODIVERSITY

Sixteen thousand species are threatened with extinction. Habitat loss is a major factor as many forests are cleared for agriculture. The UN estimates the global annual loss of primary forest is 50,000 km2.

WATER

The availability of fresh water will decline, according to the UN, who project that by 2025 1.8bn people will be affected by water scarcity. Sanitation is also a major issue, as contaminated water is the greatest single cause of human disease and death. The state of the world's fisheries is also touched on by the report which says many fish stocks are overexploited, while the demand for fish is expected to rise alongside growing populations.

URBAN GROWTH

By the end of 2007 it is estimated that more people will live in cities than rural areas for the first time in history. The satellite image of the US city of Las Vegas (left) shows how rapidly metropolitan areas can grow. The city was home to 557,000 people in 1985, by 2004 this had risen to nearly 1.7 million. This rapid growth can put pressure on water resources and infrastructure.
