00:00Thank you very much.

00:30The reasons for this decline are multiple.

00:47One of the first, which happens in Yelimapo, is the erosion of the beaches, where about

00:5340% of the turtle nests are destroyed each year.

00:56There is also the impact of accidental capture, so fishing in particular.

01:00There is also other pollution, the first of which is plastic bags in the sea,

01:06where we know that the turtle confounds them with its main prey, which are jellyfish.

01:26Thanks to the satellite data that we have been using for many years on turtles, we

01:54have been able to obtain a lot of information on their way of using resources and habitats,

01:58except that it is important now to go much further.

02:01We were able to show, thanks to the satellite data, that they were very sensitive and were

02:17really linked to the oceanographic variables.

02:20We know that this evolution, these environmental and climatic changes, will have a direct impact

02:25on these jellyfish, which makes these turtles a very good indicator of the quality of our environment.

02:30Marine airs are a very effective tool for the protection of ecosystems and also for

02:44marine turtles, except that these marine airs have a limit.

02:48Everything that happens at sea, there is no protection.

02:51There is a lot of human activity, including fishing.
