Launched to mark World Environment Day 2005, and produced by the UNEP in collaboration with organisations such as the US Geological Survey and NASA, this publication uses text, illustrations, satellite images and ground photographs to depict and analyse humanity's impact on our environment. Issues discussed include: population growth and urbanisation, natural resources consumption, land use intensification, biodiversity and habitat loss; environmental impacts and trends including global warming, air and water pollution, and the impacts on oceans and coastal zones, forests and tundra; changes that result from geo-hazards such as earthquakes and tsunamis, climate hazards such as floods and droughts, and industrial hazards such as nuclear accidents and oil spills; and suggestions for mitigating the effects of global environmental change.
