Catherine Downie, Biology Undergraduate. Planet-wide human impact on the biosphere is indisputable. In 13,000 years complex and species-rich natural habitats have been replaced with simple modified habitats specialised for agricultural production. Extinction is a natural process, but recent and current extinction rates indicate they are between 100 - 200 times higher than would be expected without the influence of humans. Essential for human survival, the amount of freshwater is limited and demands are growing remorselessly as global population continues to expand.
Freshwaters are therefore vital for our food security.
Background to WCMC The World Conservation Monitoring Centre provides information services on conservation and sustainable use of the world's living resources, and helps others to develop information systems of their own. WCMC has a global reputation for scientific rigour and excellence. This move recognises the global need for reliable information on the status of the world's species and ecosystems, and for early warning of environmental problems. As part of its remit, WCMC is developing a biodiversity information assessment and early warning system that will support the work of decision-makers in governments, the private sector and by conservation and development agencies throughout the world. When it becomes a UNEP centre in July 2000, WCMC will enjoy enhanced international status.
