I have to laugh when I read articles like this one.
The most destructive invasive species is Homo sapiens sapiens, commonly referred to as “Man” or "Human".
Purty, ain't it?
They are notorious for removing all top predators in any ecosystem that they invade. No matter the size, weight, or function of competing predators, they are absolutely relentless in the destruction of any top predators that they see as competitors. Wolves, bears, lions, tigers, panthers, foxes, weasels—nothing survives the onslaught of Man.
In addition, they also wreck every native environment and ecosystem that they encounter. Marshes and wetlands are typically drained. Hills and mountains are leveled. Rivers dammed. Forests are felled, grasslands plowed under, deserts wrecked. And they don’t stop there. Man even finds ways to destroy estuarine ecosystems and deep water environments, wiping out shellfish, fish, and marine mammal populations in the process.
Man is without a doubt the most rapacious invasive species ever to move out of its native habitat (in this case, the Rift Valley of Africa). In numerous ways they foul the water around and beneath them; they poison the air that everything needs to breathe; they even ruin the earth and actually consume the crust of the planet on which they walk. These disgusting creatures reproduce incessantly and have no natural controls on their populations. They tend to shit and urinate in their own drinking water, befoul their own air, and poison their own living spaces.
If something is not done—and soon—then this species will inevitably succeed in destroying most of the megafauna on the planet, irreparably wreck the very ecosystems on which most life depends, and find itself in extremis.
Please leave all suggestions for control of this invasive species here.
