The world’s fish migrations are collapsing – that’s a problem for millions of people

[Paco Dennis]

Hidden beneath the surface of the world’s rivers, some of Earth’s great animal movements unfold – migrations that rival, in sheer biomass, the famous mass movements of zebra and wildebeest across the Serengeti.

For centuries, fish migrations were as predictable as the seasons. Salmon, sturgeon, giant catfish and many other species moved through rivers in vast numbers, guided by rising water, flood pulses and evolved biological cues.

These species are extraordinarily diverse, ranging from beluga sturgeon – massive fish that can live for more than a century and produce the world’s most prized caviar – to giant river carp, tropical eels, gold-flecked shad and goliath catfish, all of which travel to survive, in some cases over hundreds or even thousands of miles.

Their journeys can span continents. But the fish and their migrations are disappearing.

I am sorry to read this ^^^^^

The bee population is also declining. They do a marvelous job of pollinating .

There is a decline in the songbird population.

Ice caps are melting that shouldn’t be.

The list goes on and I’m sure there are those who will espouse their ideas of reasoning for all this.

I, however, will say thanks a lot to humans for years (even centuries) of mucking everything up and killing off nature. When we find ourselves declining, don’t crybaby whine and wonder why————
