Yet water is still abundant in unspoiled regions of the planet. The wetlands.

These wetlands are crucial to all life on Earth. They represent six percent of the planet.

Marshes are sponges that regulate the flow of water. They absorb it in the wet season. . .

and release it in the dry season. The water runs off the mountain peaks, carrying with it the seeds of the regions it flows through.

This process gives birth to unique landscapes, where the diversity of species is unequaled in its richness. Under the calm water lies a veritable factory. . .

where this ultimately linked richness and diversity patiently filters the water and digests all the pollution. Marshes are indispensable environments for the regeneration and purification of water.

These wetlands were always seen as unhealthy expanses, unfit for human habitation. In our race to conquer more land, we have reclaimed them as pasture for our livestock, or as land for agriculture or building.

In the last century, half of the world's marshes were drained. We know neither their richness nor their role.

All living matter is linked. Water, air, soil, trees.

The world's magic is right in front of our eyes.
