Thanks for the opinion; however, I believe my statement is true. But let me qualify it more. Yes, I agree that the ecosystem is impacted by the “long-term” presence of the cattle, and hence animal life will change as well, along with plant life. But I think the dominating element is the weather. Pull out the cattle, and the ecosystem will attempt to revert back, insofar as the weather was the same as before the cattle were introduced. If the long-term weather has changed to a new state while the cattle were there, the reversion will be slightly different, of course. But remove the big impact factor such as the cattle, and it should revert back to some extent. Note that I am NOT saying that life will flourish, but tend to revert back to the previous state of the ecosystem, whether desolate wasteland or an oasis. The presence of the cattle may have actually improved the ecosystem so that other species flourish as well, but with removal, they would die back to levels before the cattle arrived.
THIS is truth: Everything that happens on this planet is temporary.
What was the weather 500 years ago? 5,000 years ago? Or 20,000 years ago, when sea levels were so low that the Florida peninsula was more than TWICE as big as it is now? Sgt Hooper, that was only 20,000 years ago, before humans were around to anguish over rising sea levels covering more than half of the Florida peninsula with water.
We are mold on a cheeseball on this planet, and God is our host. We are along for the ride. We don't control the climate -- it controls us.
125,000 years ago, sea levels were so HIGH that the Florida peninsula was only half the size it is now; you can even see traces of the old coastline today. But that was 125,000 years ago, l-o-o-o-o-ng before humans could gnash their teeth and drive themselves crazy over the receding waters "endangering" so much wetland.
There is zero status quo in nature; there is nothing to "revert" to. Nature operates with zero, zilch, big fat donut hole, regard to man; we're just another critter in the system with as much potential to alter things that won't mean a hill of beans 50,000 years from now.
