Endangered Species on the only known inhabited Planet

65 million years ago probably a 10 km big planetoid wiped out around the half of all at that time living species on our planet, among them all Dinosaurs, flying Saurs and water-living ones and a considerable number of another species. Even longer ago, a really all-life threatening catastrophe led to an extinction, which caused around 90 % (!) of all living species to vanish. The reasons for this last event are not well understood, partially due to the longer time back it happened, but there are a few more mass extinctions in the history of Earth and even one, which takes place at now, and this time we know without any doubt the reason for it. The only question remains, how severe our aggressive, totally unscrupulous behaviour against all other living species will be. Which of the past events we will rival with or even surpass? Should any intelligent being in millions of years in the future discover this nowadays ongoing mass extinction, it will have to solve a difficult riddle: no major impacts, no giant vulcanism on global scale, no significant long-term climatic change. What has happened? One thing is for sure: higher evolved species cause seldom casualties on themselves or even on other species, but as the example of Lemmings in Scandinavia shows, this happens nonetheless. The worst example is the mankind, which threatens the entire terrestrial biosphere and therefore also itself.

In detail we use several ways of destroying life on Earth: the most global ones are the additional heating of the atmosphere by enriching certain gases in our atmosphere, mainly due to carbon dioxide by burning fossil forms of biological mass and destruction of carbon dioxide depleting units like forests (not only rain forests, also boreal ones are reduced rapidly) altogether with methane, which is due mainly to stock-farming (cattles!), the depletion of Ozone in higher layers of the atmosphere increases the energy of the incoming ultraviolet radiation of the Sun on Earths surface, the depletion of biomass in the oceans by far to extensive fishing directly threatens all animals in these, the usage of ground for farming purposes and for buildings of all types reduces greatly the available areas for natural living animals.

Other factors, more specific for certain species, are direct hunting of them for a number of nearly exclusively totally inacceptable reasons (whaling, shooting of birds of prey, killing of mammals to get fur and so on), reducing of their nutrients directly or indirectly (compare fishing above), local human made catastrophes like fuel leakages of any type (for example pipelines especially in Russia are a big threat) and a number of further reasons, one is, extensive enlighting of cities at night, which disturbs the living cycles of animals in theses regions cause major negative impacts on the biosphere or at least significant parts of it.

The heating of atmosphere alone is a great danger, because plants and most animals can't cope with the - in evolutional terms - rapid shift of climatic zones, which is connected with this tendency. Only a global effort can limit the unavoidable damages to Earths biosphere anyway. And the only global organization that in my view fulfills all minimum requests for that difficult task is the WWF, which means World Wide Fund for nature (formerly known as World Widelife Fund). To bundle these efforts, it would be fine, if more people would join it. Now I present three main sites of it: the international, US and German member organizations of it.

These sites enable all people in the world the access on the world wide but also the special local projects of the selected regions. For a number of important countries own homepages exist, the other countries should use the international one or a homepage of a close neighbor for getting the appropriate informations. For it's a global effort, the projects and country groups are ever growing, the most important ones are very ambitious, but absolute necessary, if we want the things get really better.


German flag Deutsche WWF Homepage
Ohne Frames, für jeden benutzbar, präsentiert sich der WWF Deutschland. Hier kann man sich über die aktuellen nationalen und internationalen Projekte informieren; als ein besonders finanzkräftiges Mitglied des Gesamt-WWF nimmt die deutsche Gruppe naturgemäß an besonders vielen internationalen Projekten teil, insbesondere in ärmeren Regionen, denen von anderen Ländern finanziell unter die Arme gegriffen werden muß. Das ändert aber nichts daran, daß es auch z.B. im Wattenmeer einzigartige Biotope gibt, die für uns besonders wichtig und auch global mit am schützenswertesten sind.
