The future of the oceans and rivers.

The researcher’s article

Judgement day is on a clock.

The judgement day clock marks 100 seconds to the end of the world. It isn’t a biblical prophecy. But an imminent warning launched at the beginning of 2020 by a group of scientists of the Doomsday Clock, a metaphorical clock that measures the time left for mankind on the planet.

If you tell a story, then everything changes.

Climate change warns man of an imminent danger: the extinction of living species, the end of life on the planet. In the eyes of someone who deals with science, and not only that, the state of health of the seas is a very clear and distinctive clue of an already solved puzzle. The researchers explain the reason.

Professor of Conservation and Ecosystem Management and Marine Biology.
Research field in reference to the short film: climate change.

Antonio Pusceddu is a teacher of Conservation and Ecosystem Management. He also teaches Marine Biology at University of Cagliari. The realisation of the short film draws its inspiration on the reflection on climate change, the rise of temperatures, the men’s responsibility in the altering of the marine and terrestrial ecosystem’s balance.

The footprint of human activities has left a mark also on the depths of the seas. Pollution, rising temperatures, CO2 emissions and ocean acidification are among the causes attributed to the alteration of the balance of the marine ecosystem.
The research tells these aspects and attests to the responsibility of man in many activities related to the change of the marine habitat: among these, the reduction of biodiversity, the alteration of the physical and chemical composition of the oceanic seabed, the disappearance of important living species, indicators of the state of health of the seas.

Studies also show how other activities, such as mariculture and trawling, for example, have been partially responsible for changes in the marine habitat, to the detriment of all forms of life, plants and animals.
