BigTex, there are a number of holes in your arguement, to the point where it doesn't hold water.

One: It doesn't take much intelligence to become a threat to every ecosystem in which the species in question (humans) is present. All it takes is the ability to reproduce in excess of replacement numbers, plus the opposable thumb, plus the ability to control fire.
Control of fire consists of two elements. One is the ability to make and use tools. That ability is present in chimps, bonobos, a couple of other ape species, and even some bird species. Two is the absence of a paralyzing fear of fire, which is not a function of intelligence as such, but of the feedback systems that produce fear, which are endocrinological. With those two elements, any dummy would be able to notice that a) some things burn (e.g. plant matter), others don't (rocks, water), and then figured out how to pick up a burning stick from a grassland fire or forest fire and use it to light some grass or twigs piled up with some rocks around them, and thereby keep warm at night and keep other predatory animals away.
Once that trick had been done the first time, it would spread rapidly to other humans. As human populations grew, the use of fire would increase, to the point where they could cause massive ecosystem damage. Think of Easter Island or the deforestation of Great Britain, on a global scale. Apes that could control fire, could effectively trash the planet.
And the reason that dolphins, whales, and elephants can afford to be as smart as they are without crashing their own ecosystems, is that they lack opposable thumbs. You can't do all that much damage with flippers or a prehensile trunk.

Two, intelligence is a check and balance against instincts that lead to ecological collapse.
The instinctive drive to reproduce is universal among all animal species and its effects are held in check only by superior predators at each step in the various food chains. Animals in food chains routinely suffer population explosions and collapses. Rabbits and wolves are a typical example, and no one would assert that wolves are too smart for their own good.
The instinctive desire to consume beyond actual physical need is present in most higher apes, certainly in chimps. A baby chimpanzee will instinctively reach out and grasp at any object that is shiny or sparkly and novel. The advertising phrase "shiny and new" is a direct expression of this instinct in its most raw form.
Among humans, there is a strong inverse correlation between intelligence and reproduction. To put it bluntly, smart people have few offspring and put more effort into raising each one, and stupid people have many offspring and put much less effort into raising each one. Also, at the present time (actually since about the 1950s), smart people tend to be more aware of the impact of overpopulation (foresight) and thus choose to have fewer offspring, whereas stupid people could give a flying f--- as long as they can f--- today and worry about the consequences tomorrow.
The element of foresight is also inversely correlated with consumption levels relative to other humans. Those with less foresight consume more, and those with more foresight consume less. The item "relative to other humans" is interesting, because it is also a function of intelligence: "somewhat smarter" humans will tend to use the "relative to other humans" metric, but "very much smarter" humans will tend to use a metric that is related to sustainability as a broader issue.
That is to say, a modestly smarter person will say "I'm doing my part, I use less of XYZ than my neighbors," whereas a much smarter person will say "I'm using X percent less than my neighbors but that's still not good enough since in order to be sustainable based on the latest findings I need to use Y amount or less."
Generally speaking, once humans recognize what their opposable thumbs are good for (aside from inserting into pies to pull out plums:-) and can control fire, it takes a substantial increase in intelligence to prevent overshoot and collapse.

By the way, at present, Cuba is the only country that is on an exact par with what is globally sustainable on a planet of 6.5 billion humans. That means among other things, no private automobiles, and an average monthly household electricity consumption level of at most 72 KWH. Note that 72 KWH means you cannot have your own refrigerator/freezer.
I'm a conservation freak to the point where I built my own high-efficiency fridge/freezer system, and the best I can achieve so far is a total of 109 KWH/month, which would be on par with sustainability on a planet with at most 4.3 billion humans. For comparison, the average household power consumption in the US is in the range of 500 KWH/month, which is on par with sustainability on a planet with at most 937 million humans. That shows you how far we have to go.

Suicide has nothing to do with intelligence and everything to do with emotional state. The degree of intelligence it takes to comprehend the idea of putting oneself out of one's own misery is less than that needed to do the things that trash the planet.

Where you say "the ultimate elegance in a life form is how long it is able to survive," you disprove your own starting hypothesis conclusively. At some point the sun will go nova and take out the inner planets. At that point the ability to survive will depend upon humans having had the intelligence and the foresight to have taken all of the numerous steps needed to diversify far beyond Earth and into other star systems. When the sun goes nova, either our intelligence will have enabled us to survive longer than that, or our lack of intelligence will have led to our extinction.
Thank you. Excellent points. Slices it a lot more finely than I did.
There is a LOT of optimism in your views. That's good. The idea that we will still be around when the sun goes nova is hard for me to conceive, but it's certainly possible.
Your assertion that people of very high intelligence are more able to grasp the importance of sustainability is suspect just because I haven't seen this myself in people of very high intelligence. Some are interested in sustainability, some are just seeking maximum profit and the rest are James Bond villains. I don't know that enlightenment is more concentrated at the highest levels of intelligence. It might be, though.
I think we come closest to agreeing when you say that whales and dolphins can't do too much damage because they don't have opposable thumbs. Exactly. They have found a way to have both high intelligence and yet remain a part of their ecosystems, which should provide them with a durable competitive advantage when it comes to survival (relative to their peers), though they are going to be screwed when the sun goes nova (unless the Star Trek crew travels through time and rescues them because they are the only creatures that can talk to the aliens of the future, as in Star Trek 5 or 6, I believe).
Maybe I should have titled the post Declining Marginal Returns on Opposable Thumbs.
