Australia faces a new problem of extinction, that of the karstic springs. Extinction has been one of the most constant phenomena during the past and present century. There are many species, both animals and vegetables that have come to an end. And once again history repeats itself.
The damage that each karst on the planet is receiving demonstrates the level at which temperatures are affecting all ecosystems. It seems that we are finally becoming aware of it. And governments are taking good note. At least the Paris Agreement of 2015, integrated 195 countries in the search for new solutions.
The issue is that the impact is increasingly aggressive. It is precisely the first world countries that generate the most pollution. China is currently the country with the highest pollution, with an impressive level of CO2.
Meanwhile, scientists with the help of institutions continue to carry out research to anticipate how to solve current problems. A recent study showed that the natural scenarios that are part of World Heritage are now more exposed. The number of threatened natural ecosystems increased from 32 to 62 in a period of only three years.
Here is a summary of some of the places that are at risk of disappearing forever and being part of the history of mankind:
Australian karst springs
Located in the south of the country, karst springs are at great risk of extinction. They house at least 50 species of freshwater crabs, of which 17 are already in the critical situation of becoming extinct. These springs represent an extension of 8 square kilometers.
The Aral Sea is located in Uzbekistan. It is considered the fourth largest lake on the planet. It reached an area of 68,000 square kilometers. Today only 10% survive. Its most chronic data reveals that 28 of its marine species came to extinction. Therefore, it has been declared as an ecosystem that has failed.
Returning to Australia, according to the International Union for the Conservation of Nature, the famous Coorong National Park, which is full of lakes, lagoons and forests is also in a critical phase of extinction.
At the moment, Coorong’s natural surface is barely 10% alive than it had at the time of greatest glory. Much of the devastating effect that this park faces is due to the effect of agricultural land.
In addition to the karst, the Sydney wetland area has also been exposed. Fracking on the one hand has generated a strong impact, as well as the expansion of urban life and mining, in addition to fires. So the coastal swamps found in Sydney have been disappearing.
It is estimated that 60% of wetlands in this region have been degrading.
Murray River Basin
In Australia, some of its most important rivers are Murray and Darling. Thanks to them, the life of forests and lakes remains active. However, given the way in which water resources are being exploited for agricultural production, great damage to the ecosystem has been generated.
Now it is clear that only 18% of the wetland vegetation survives. At another time, the Murray River Basin was much more vigorous and beautiful. Now, the risk of extinction is high.
On Howe Island, the presence of clouds was essential in the vegetation ecosystem. But, the clouds have begun to lose presence in the skies of this island, so that the quality of life of the wetlands has fallen considerably.
The contribution that this forest provides to the country and the area is really impressive. But as water resources have been decreasing, the humidity level has decreased considerably. The forests of this island are at total risk of extinction if clear measures are not taken to strengthen the vegetation
