The cetaceans threatened in the Tuscan sea

63,000 tons of pressed plastic spilled by the ship Ivy due to a storm have been there for five years on the seabed of the Tuscan Archipelago. Stefano Ciafani, chairman of Legambiente assosartion asking the Council of Ministers for a state of emergency: "A real time bomb for the marine environment, which he is not dealing with of the problem"

Greenpeace, located in the waters of the Tuscan Archipelago for the Defend the Sea research expedition conducted with the Bamboo boat, published an investigation a month ago, A bales sanctuary, for shed light on responsibilities.

In these days the environmental organization together with the researchers of the Cnr-Ias of Genoa and the Polytechnic University of the Marche is carrying out monitoring in the area to understand if the plastic dispersed on the seabed has generated an impact in the waters of the Sanctuary and the Gulf of Follonica in terms of release of microplastics.

"It is paradoxical - underlines Giuseppe Ungherese - that it is a small organization with limited financial resources like Greenpeace to carry out such research. On the other hand, what can we expect from all those institutions that for five years have failed to recover the tons of plastic that lie at the bottom of the sea?" The result is very serious: under the astonished eyes of the communities of the Tuscan archipelago and of the whole country, the 40 "surviving" eco-bales of the cargo lost at sea - originally consisting of as many as 56 eco-bales - are slowly flaking, with very serious and perhaps irreversible damage for the marine ecosystem of the Upper Tyrrhenian Sea and with consequences still not assessable for the Pelagos Cetacean Sanctuary.

"Stop this absurd and incomprehensible downloadable without further delay - insists Legambiente - and proceed to declare the state of emergency as soon as possible, to appoint a new commissioner and finally to remove what is being announced as a real ecological time bomb for our marine environment."

Polar bears may disappear in the 2100

Polar bears could become extinct by 2100. These are the conclusions of a study published in Nature Climate Change. This study highlights that if we didn't stop climate change, polar bears could run out of food and die.

The main author of the study is Peter Molnar and analyzed 80% of the total polar bear population. These data have been compared with those deriving from possible future projections on ice by 2100, if we keep the same CO2 production, this will be the result.

With the reduction of ice, bears will have to fast surviving with only the accumulated fat. They would die of hunger, given the extreme difficulty in finding food. This could lead them to the brink of extinction, leaving them only in the northernmost area of ​​the Arctic.

When fasting bears are used to not moving or doing it as little as possible in order to save energy. The reduction of ice will also lead to a drastic drop in the population. The time it takes for bears to find a mate will lengthen, which will cause these animals to move despite fasting, burning energy unnecessarily.

The fate of polar bears has long been predicted and used as a warning to remember what the effects that human-caused climate change could bring. Critics who don't believe in climate change claim that fear of polar bear extinction is exaggerated as they have been able to survive despite high temperatures and food shortages.

Obviously, scientists don't accept this argument. Their answer is that in all likelihood, bears had access to alternative sources of food in previous hot periods, which no longer occurs.
