00:00Today, June 8th, is the World's Day of the Ocean.
00:03Surely you will ask why we are going to dedicate a special date to the ocean,
00:08if it is marketing, or is a public spot,
00:11or really serves to be aware of this ecosystem.
00:15But Pille, this day is fundamental to make awareness
00:18about the importance of this ecosystem,
00:20which is responsible for producing the biggest amount of oxygen
00:23that we breathe in the Earth.
00:24It is also a key factor in the fight against climate change.
00:28Well, the story begins so.
00:30In 1992, during the summit of the Earth of Rio de Janeiro,
00:34according to the UNESCO,
00:36a group of experts began with the idea
00:38to dedicate a single day to the ocean.
00:41That idea was flying, but in 2008,
00:44another group of scientists landed
00:46and through the United Nations Organization,
00:49the ONU, decided to declare this day
00:52as the World's Day of the Ocean.
00:54Every year, there is a special name
00:56with the purpose of protecting them
00:59and explaining, once again,
01:01the importance of these ecosystems.
01:03The Lema of 2023 is
01:05The Mareas change.
01:06But why the ocean are so important?
01:09The first thing we have to take into account
01:10is that we have five.
01:13Atlantic, Pacífico, Índico, Ártico and Antártico.
01:17They are responsible for the important part
01:19of the oxygen oxygen in the Earth.
01:22They are estimated that between 50 and 80%.
01:25This is due to the photosynthesis
01:27of the ocean plankton.
01:29They are the house of at least 230.000 species
01:32of plants, invertebrados, vertebrados
01:35and peces.
01:36In fact, the researchers say that
01:38for every marine species known by science,
01:41there are at least four that still don't know.
01:44What's surprising, isn't it?
01:45And as if it were a few,
01:46they are essential for the regulation
01:48of the climate climate,
01:50as they absorb carbon dioxide
01:51and the heat of the atmosphere.
01:53Another of its key functions
01:54is that the economy
01:56and the local, national and national media.
01:59A group of researchers very tense
02:01about the climate change
02:03determined that
02:04about the 28% of the world's population
02:06live in coastal regions
02:08and that more than 2.000 million people
02:10depend directly or indirectly
02:12of the marine ecosystems.
02:14Just to make you an idea,
02:16the ocean provides approximately
02:19170 million tons of marine species
02:22per year,
02:23about the 15% of all the proteins
02:25we humans consume.
02:27A pesar de su importancia,
02:29los océanos se enfrentan
02:30a una serie de riesgos.
02:32Aquí le contamos
02:33algunos de los datos
02:34más alarmantes.
02:35En los últimos 150 años,
02:37se han perdido aproximadamente
02:39la mitad de los corales vivos.
02:41Además,
02:42la contaminación por plásticos
02:43se ha multiplicado por 10
02:45en los últimos 40 años.
02:48A esto se le suma
02:49que un tercio
02:49de las poblaciones de peces
02:51están sobreexplotadas.
02:53Y como cereza del pastel,
02:55las zonas muertas
02:56que son aquellos lugares
02:57donde no prospera la vida
02:58porque no hay oxígeno,
02:59están aumentando rápidamente,
03:01tanto en número
03:02como en extensión.
