We live in a dynamic world, and habitats are always undergoing changes at all sorts of levels. However, natural changes usually occur at a slow pace so that impacts on individual species tend to be slight - at least in the short term
When the pace of change is greatly accelerated, there may be no time for individual species to react to new circumstances, and the effects can be disastrous. Briefly, this is the reason that rapid habitat loss is regarded as the chief cause of species endangerment, and there is no force more powerful in this regard than human beings. To some extent, every part of the earth has been affected by human activities, especially during this past century. This applies on virtually every scale, from the loss of microbes in soils that once supported tropical forests, to the extinction of fish and other aquatic species in polluted freshwater habitats, to changes in global climate caused by the release of greenhouse gases. From the perspective of an individual human lifetime, such changes may be hard to detect and their effects on individual species may be hard to predict. But the lesson is clear enough. For example, although many countries have had plans to grow many tropical forests, they are highly susceptible to destruction because the soils in which they grow are poor in available nutrients. Centuries may be required to bring back a forest that was cut down or burnt out in the space of a few years. Many of the world's severely threatened animals and plants live in such forests, and it is certain that huge numbers of them will disappear if present rates of forest loss continue. Habitats in the world are unchangeable and fixedly exist.
