Hello @juanbg, this post is very good, although it saddens me, to see how humanity is capable of violating such beautiful animals and that like the rest of the creatures, they have their niche and their ecological function. This post is very didactic and illustrative of how detrimental human activity can be in ecosystems and with respect to a specific species.

In my country, Venezuela, many times when I traveled along the Orinoco River or visited the towns and cities that are on its banks, I could see the toninas, which are pink river dolphins. These animals have many stories, it is said that they have saved shipwrecked people from succumbing to the terrible current of the river, dragging them to safety or to the shore. I have always loved the beautiful spectacle of watching them leap over the surface of the water, or swim alongside the vessel, be it a large boat or a canoe. I believe that today, due to predation, pollution and the accelerated deterioration of the entire south of my country, they are no longer seen, it is a tragedy that this is happening.
