1
People often ask me why should we care about coral reefs?
Les gens me demandent souvent pourquoi nous devrions nous soucier des récifs coralliens ?
2
Corals build one of the most important ecosystems in the ocean.
Les coraux construisent l'un des écosystèmes les plus importants de l'océan.
3
They are animals, but they look like rocks
Ce sont des animaux, mais ils ressemblent à des roches.
4
because they make a skeleton underneath themselves and they leave it behind as they grow up toward the sun.
5
And then that creates homes for sponges and clams and snails.
6
And those smaller organisms are what feed the bigger fish and the bigger fish.
7
So without the corals, you slowly lose the ability to support the entire pyramid.
8
People often don't realize that they help protect the shorelines from waves, from big storms and from hurricanes.
9
We know that corals can live for a long time, but what's particularly interesting about that is
10
that they're living in the blazing hot sun near the equator for hundreds and hundreds of years.
11
So now scientists are looking into how a coral manages to repair its DNA
12
when it's sitting in the blazing sun for decades and decades,
13
and hopefully we can understand how to prevent the mutations that eventually lead to cancer in humans.
14
Corals live with algae in their tissues.
15
It would be as if you had lettuce growing under your skin
16
and you were able to use the calories that that lettuce was making without eating any food.
17
When a coral bleaches, the balance between that algae and that host coral sometimes goes off.
18
The coral spits out those symbiotic partners
19
and it's very difficult for them to survive because they've lost their main source of food.
20
Unfortunately, anywhere you have humans, corals tend to suffer.
21
And that's because all the activities that we do on land, things like building, things like discharging sewage, things like agriculture, those all affect the ocean.
22
A country that's doing a very strong job of conservation is Palau.
23
They saw a massive coral bleaching event in 1998 and realized that they were at risk from the changes occurring globally.
24
So they started putting in place fisheries regulations, a marine park, they eventually put in a shark sanctuary,
25
and now they have 80% of their water protected from any kind of fishing or mining.
26
What we know now is that the sort of days of hoping and wishing for those coral reefs to survive is over.
27
This treasure will help us get through the next era of development, as long as we're just kind enough and wise enough to be sure
28
that they all come along together with us into the future safely and protected.

Qu'est-ce que la technique du Shadowing ?

Le Shadowing est une technique d'apprentissage des langues fondée sur la science, développée à l'origine pour la formation des interprètes professionnels. Le principe est simple mais puissant : vous écoutez de l'anglais natif et le répétez immédiatement à voix haute — comme une ombre suivant le locuteur avec un décalage de 1 à 2 secondes. Les recherches montrent une amélioration significative de la précision de la prononciation, de l'intonation, du rythme, des liaisons, de la compréhension orale et de la fluidité.
