Les mousses sont comme les héros méconnus du monde végétal. Elles peuvent survivre dans des conditions extrêmes, des déserts à l'Arctique, ce qui les rend incroyablement résistantes. Les mousses aident à prévenir l'érosion des sols en retenant la terre avec leurs minuscules racines. Elles absorbent également des tonnes de dioxyde de carbone, contribuant ainsi à lutter contre le changement climatique. En plus, elles créent des tapis luxuriants et verts qui rendent les forêts et les jardins magiques ! Animation créée par Sympa.

FunTranscript
00:00The majestic trees and the colourful flowers need to make some room,
00:05because an unknown hero of the plant world emerges from the shadows.
00:09Foam, this humble green carpet of nature, must not be underestimated.
00:14In a new study, scientists have finally uncovered the secret of foam,
00:18and have revealed the crucial importance of these little botanical wonders for the ecosystems of the globe.
00:24Researchers have explored more than a hundred sites across eight different ecosystems
00:29during an expedition in search of foam that would have made Indiana Jones want to live.
00:34They discovered that the latter covered an amazing surface of 9.4 million square kilometres,
00:40equivalent to that of Canada.
00:43So, what makes these foams so unique?
00:46To begin with, they do not have the sophisticated plumbing system that ordinary plants have.
00:52Instead, they survive by skillfully absorbing the water from the atmosphere,
00:57behaving like small natural sponges.
01:01Some foams, especially those of the arid regions of Australia, have mastered the art of survival.
01:07When conditions become difficult and water becomes scarce, they do not perish like other plants.
01:13Instead, they fold into a compact ball and enter a suspended state of animation,
01:19similar to hibernation.
01:22Scientists have even studied foams that remained in a ball for a century.
01:28By offering them a few drops of water, they regain life, defying the principles of plant decomposition.
01:35But what is their impact on the environment?
01:38These super-heroines in green glue play an essential role in the cycle of nutrients,
01:43providing valuable help through elements such as nitrogen, phosphorus and organic materials.
01:49Foam soils, compared to those without foam in the study, were much more fertile.
01:55Foams manage nutrients very effectively and store enormous amounts of carbon,
02:00which would otherwise contribute to the greenhouse effect.
02:04But here is the icing on the cake.
02:06Foams are also excellent at repelling unwanted pathogenic agents.
02:11Scientists have discovered that areas covered in foam have less potential diseases than plants in their soil.
02:17Now let's talk about the landscape skills of foam.
02:20These plants with overgrown roots act like the natural architects of the soil,
02:25maintaining everything together like a huge construction team.
02:29Their shallow roots create a stable surface that allows a wide variety of plants to thrive,
02:34thus favoring the emergence of complex ecological systems
02:38In places where trees are not allowed to grow, such as deserts and tundras,
02:43it is the foams that take over.
02:46These resilient organisms dominate the harsh environments,
02:49bringing life and diversity where trees do not even dare to venture.
02:54The densest foams create luxuriant carpets and lawns
02:57that enrich the soils and ecosystems of these apparently inhospitable regions.
03:03There is one last asset left in the sleeve of our foams.
03:06After major disturbances, such as volcanic eruptions that leave the soil sterile and desolate,
03:12guess who is the first to come back?
03:15Alongside cyanobacteria and resilient algae,
03:18the foams quickly colonize the devastated landscape,
03:21starting the regeneration process.
03:24Some foams are also true magicians of light.
03:28They can quickly adapt to low-light conditions and even grow in caves.
03:34A particular species, the Schistostega pennata,
03:38is nicknamed the dragon's gold.
03:41This foam offers a dazzling spectacle, shining with a sparkling emerald green.
03:46How does it manage to be so bright, you ask?
03:49First of all, thanks to the protonema,
03:52these amazing filiform structures that germinate from a foam spore.
03:56Inside these little wonders, special cells regroup
04:00to absorb each available ray of light.
04:03And as if that were not enough,
04:05some cells in the form of lenses accentuate this effect by concentrating the light.
04:10And it really shines.
04:12When the light is reflected, it creates this dazzling green glow,
04:16like a true pyrotechnic spectacle of nature.
04:19It is so incredible that some people in Japan
04:22even decided to make this plant a natural monument.
04:26The foams do not just make the caves magical.
04:29They also make remarkable habitats for fascinating creatures.
04:33Let's take, for example, the punctuated turtles of Ontario, Canada.
04:37When winter strikes with its icy fury
04:40and temperatures drop to incredibly low levels,
04:43these turtles nest under a type of foam called sphagnum.
04:47Fortunately, you do not need to travel to Canada
04:50to see these incredible foams in action.
04:53You can also find them in the United Kingdom,
04:55where they form spongy carpets covering the soil of lands and swamps.
04:59A study focused on the evolution of plants
05:02reveals that the foams were the very first plants on Earth.
05:06At least technically speaking.
05:08At that time, the Earth was a bald planet,
05:11devoid of any lush vegetation.
05:14No shrubs, no trees,
05:16not even a sprig of grass to break the monotony.
05:19Initially, scientists thought that the first plants
05:23to venture on land were simple organisms.
05:26However, these new researches upset this conception.
05:30It turns out that the first foams were far from being basic,
05:33and were in fact quite complex.
05:36In the midst of this extended desolation,
05:38these amazing plants, namely foams,
05:41anthoceroses and hepatites,
05:43have proven to be the true pioneers of plant life on Earth.
05:47You may think,
05:50But wait,
05:51aren't hepatites those sticky and spongy things
05:54that I find in my garden after an aversion?
05:57Well, yes,
05:58but don't be fooled by their modest appearance.
06:02Although some consider foam to be a harm in terms of gardening,
06:06it can actually be a fantastic addition to your outdoor oasis.
06:11The best thing about having a foamy garden,
06:13you have total control over its appearance,
06:16because you can grow foam as a base,
06:19hang it on a ledge,
06:20or even grow it on rocks for an authentic tropical forest atmosphere.
06:25You can also bring foam inside by growing it in containers,
06:29terrariums,
06:30or on plant walls.
06:32Before diving into the foam culture,
06:35let's talk about the different types you can take advantage of.
06:39There is the acrocarp foam, which grows vertically
06:42and has cute little stems that glow like fireworks.
06:46It is delicate,
06:47so be careful not to disturb it or walk on it.
06:51On the other hand,
06:52there is the pleurocarp foam,
06:54which looks more like a fern and spreads out more,
06:58like a comfortable carpet.
07:00This one can withstand a little more passage
07:02and external disturbances.
07:06Why choose foam rather than other types of plants?
07:09Well, first of all,
07:10it requires little maintenance.
07:12Say goodbye to these endless hours spent watering
07:15and maintaining your garden.
07:17Foam can survive for months without water,
07:20and even if it dries up,
07:21it usually comes back to life on its own.
07:24Unlike other plants that absorb a lot of water
07:26and depend on fertilizers,
07:28foam is content with little humidity
07:30and does not need chemical products to thrive.
07:34Thus,
07:35not only will you save water,
07:37but you will also prevent harmful substances
07:39from infiltrating the soil.
07:41Foam is also a natural air purifier.
07:44When it is grown indoors,
07:46it acts like a biofiltration system,
07:49absorbing harmful particles,
07:51turning them into pure air
07:53and then releasing them into your living space.
07:56Now that you are convinced of the wonders of foam,
07:59let's talk about the right time to grow it.
08:02The best time to grow foam is early spring,
08:05when the sun's rays reach a lower angle
08:08and the ground is still wet from the rain and snow of winter.
08:11For the culture of foam indoors,
08:13the choice is yours.
08:15Just make sure to provide your foam
08:17with a little sunlight and water
08:19and regulate the temperature of your home.
08:22This can be a little tricky
08:24depending on the location of your house
08:26or the amount of sunlight available.
08:28But don't worry,
08:29with a little planning and effort,
08:31you can create the ideal environment
08:33for your foam to thrive indoors.
08:36And let's not forget the wonderful world of terrariums.
08:39If you want to create your own miniature foamy landscape,
08:42a terrarium is what you need.
08:44All you need is a glass container,
08:47a few pebbles,
08:48a pinch of granulated coal,
08:50soil and a piece of foam mat.
08:53And above all,
08:54remember to avoid rolling stones.
08:56They don't pile up.
08:57Well, you know.
