ABSTRACT
As environmental degradation of the Earth grew, it became evident that a number of environmental problems were very large in scale. Certain types of degradation, such as large-scale air pollution, became a regional problem: in some cases, a continental problem. Transboundary air pollution from industrial sources and coal-burning power stations is an example. Some problems are even bigger, and global in scale. Such environmental misadventures are affecting or threatening to affect the entire planet. The two biggest are stratospheric ozone depletion and global warming. If they continue unabated, these two will affect every individual on Earth in one form or another. Their solutions require global efforts and co-operation.
