Brazil wetlands with a unique biodiversity.

The wetlands represent 6% of the surface of the planet, under their calm water lies a veritable factory where plants and micro-organisms patiently filter the water and digest all the pollution. These marshes are indispensable environments for the regeneration and purification of water The worlds largest wetlands are on the borders of Brazil, Bolivia and Paraguay. Pantanal is unique for its biodiversity. During the 20th century, humanity drained or otherwise destroyed half the wetlands on the planet, decrying them as unhealthy and converting them into agricultural or building land. In Brazil, herders and sugar cane planters are gradually appropriating these vast wetlands.
