Oceans: sad GIFs

Publié le 25/09/2015

Every fortnight, WeDoData will share innovative formats spotted around the COP21. First chronicle today on the state of the oceans, inspired by the work of the scientist Sylvia Earle and her documentary Mission Blue.


Between 1950 and 2014, 95% of Pacific bluefin tuna and North Altlantic cod disappeared.

Will the ocean issue be addressed on the negotiating table at the COP21? This is what the ocean advocates hope, pointing out that the first oxygen suppliers on the planet also absorb about a quarter of the carbon emissions released into the atmosphere by human activity. Yet, despite its key role in the regulation of climate change, the ocean ecosystem has not been invited.


Between 1950 and 2014, half of the coral reefs across the oceans died.

After witnessing the effects of pollution, acidification and overexploitation on oceans for five decades, the American biologist Sylvia Earle compiled an edifying documentary entitled “Mission Blue”. Four Gifs were extracted from this documentary, which unveil some very disturbing data: in 65 years, half of the coral reefs have disappeared; we estimate the oceans host about 30,000 oil drilling sites today, while the first one was set up in 1947…


In 1947, there was just one oil drilling site. In 2014, there were more than 30 000.

Watch also Sylvia Earle’s TED talk, and more and more data on WeDoData’s website.
