British Antarctic Survey researchers have discovered marine life under an ice shelf in Antarctica. The important discovery took place during the drilling of the Filchner-Ronne ice shelf, 900 meters thick. A camera was lowered into the hole looking for mud on the bottom.
However, the video footage showed 16 sponges and 22 unidentified animals, possibly crustaceans. Huw Griffiths of the British Antarctic Survey said: “There are every reason why they shouldn't be there. The finding suggests that life in Antarctica's harshest environments is more adaptable and more biodiverse than we think.
It's not a graveyard that some things cling to, it's more complicated than we thought. When ice sheets collapse due to global warming, species such as those found on the boulder may not be able to adapt to rapid changes."
Saimaa seals slaughtered by intensive fishing
Global warming has damaged the habitat for seals in the Saimaa, an area around the lakes of Saimaa, in Finland, where too little snow falls by now, so female seals are forced to give birth on ice, with serious risks for their survival.
WWF said that many specimens were trapped in nets placed underwater by fishermen and drowned. Saimaa seals are at risk of extinction due to the fishing nets in which they are accidentally caught. World Wildlife Fund hopes and demands that the Finnish government make various laws to protect the habitat of the species.
According to estimates, the number of Saimaa seals living in the wild are just between 260 and 410. Mervi Kunnasranta of the University of Eastern Finland, said that artificial snow banks are currently being built to help animals, but it is a waste of resources because seals live there, grow and proliferate in the spring, and then fall victim to nets in the same areas, often posed by hobby fishermen.
In the month of July there was the highest number of seals trapped in nets and drowned death. It would be necessary to ban fishing from mid-April to the end of June, which is carried out with small nets and therefore not dangerous for threatened amphibian mammals, but the bill is insufficient.
It is necessary prohibit fishing of all kinds, even the smallest fish, until the end of July. The protected area intended as a nature reserve for seals should also be extended beyond the proposed 300 square kilometers.
