When imbalances in an ecosystem occur, the ecosystem will find ways to correct it until a new balance is achieved. It is flexible and can adapt to different kinds of changes. The ecosystem is strong that way.
However, it is also fragile because any changes in one "component" may have a chain effect and cause changes in many other "components" in the ecosystem. The ecosystem will keep trying to adapt and re-balance until a tipping point is reached and ecosystem won't be able to sustain itself anymore.
It would be a point of no return. It is scary to think that we may be reaching that point.

It reminded me of a dialog in this French movie La Haine (Hate):
"Heard about the guy who fell off a skyscraper?" asks Hubert. "On his way down past each floor, he kept saying, to reassure himself, 'so far so good... so far so good... so far so good.' Then he hits the bottom. How you fall doesn't matter. It's how you land."

Hi Donna,
Your explaination of ecosystems is great. It seems that a continuous component that keeps coming up with ecosystems is balance. I agree with you that we are getting to the point of being so out of balance that it is getting scary.
I also really enjoyed the quote you posted from the movie, it is so true. I was in Utah once and I saw this guy jump off of a cliff (with a parachute) but his parachute malfunctioned and he hit the cliff and bounced off it a bunch of times as he fell about 100 feet and then his parachute managed to get caught on a rock and stop his fall 3 feet above a huge legde. The impact from his harness stopping his fall caused him to brake his pelvis in 3 places, but it stopped him from hitting the ledge and saved his life.
