If I want a greasy hamburger, and in the pursuit of a hamburger go to my kitchen and spill hamburger grease on the floor, yes I have caused damage to the ecosystem that is my kitchen. But this has nothing to do with scarcity of hamburger meat.
even more so our efforts to get at recourses that are harder to reach
Justify that. None of your examples support your premise. Rainforest deforestation is not because we're trying harder to get to increasingly out of the way forests. Ocean microfauana is not being depleted because we're trying increasingly hard to eat those fish that are just a little bit harder to get to.
None of this has anything to do with scarcity.
Apparently you have never been taught that to make your hamburger, rain forest is cut down, and a whole continental coast is losing / has lost a great deal of it's marine biodiversity?
It's quite easy. A large percentage of rainforest deforestation is to make room to grow soy. Yes, soy.
Now you can say: You see! Now that's why I eat hamburgers, instead of being a tofu-eating vegetarian whose self-presumed morally superior eating habits damage the rainforest!
But wait.. A closer inspection reveals, that this soy is actually grown to be processed into... livestock food. Mostly for cows, used in the meat industry that makes your hamburgers, and every bloody hamburger that is mondially being pushed through throats by certain 'international' franchises.
A direct effect of these soyfields, is that rainforest is cut down.
A less direct, but devestating consequence:
Live rainforest soil is a thick spongelike soil layer. It can absorb and hold tremendous amounts of rain. With this absorbtion, it makes sure the scarce nutrients are trapped instead of washed out, to be used by the vegetation which thrives upon it (rainforest, despite looking very lush, are actually on very poor soil, nutrient wise).
Then the rainforest is cut, more often burned, to make room for another high tech, corporate sponsored soy megafield.
Since the soil is so very poor, soy farmers need to use a lot of fertilizers.
This, combined with the soil's loss of capacity to trap and hold rainwater, after the rainforest has been burned down, leads to 1000s of tons of fertilizer being washed out of the farms, into rivers, and through those, into the ocean each year.
The South-American coastline has lost a lot of it's biodiversity, suffocated by algae and other microorganisms thriving on the massive influx of fertilizers.
Since we can safely assume that unless ww3 happens and escalates into nuclear mass destruction, or ebola learns to swim, fly, and jump through a hoop, world population will keep growing, as it does now.
Bearing that in mind I can only conclude that eating your greasy hamburger, and even taking it for granted, has a lot to do with scarcity. The fishermen along the South-American coast can tell you all about it.
African oilspills are not because were trying harder to get to increasingly out of the way oil wells.
I say they are. If oil was more sustainably available in countries that do have the political stability to make sure that thieves and saboteurs cannot cause oil spills, (or have the power of office to resist corporate bribes and actually enforce high-standard safety laws) Shell wouldn't be all over the place there. They are only there because global demand exceeds availability of more sustainable oil (or should I say, energy?).
Unfortunatly "sustainable" has been twisted in most corporate beliefs to mean "profitable", which further complicates matters
From another perspective - why are those countires prone to banditry, and corruption of office? Might that have something to do with scarcity, more in general? Scarcity of means to survive, perhaps? Or, to come back to my first reply I made in this thread, because for most people in Africa, money is scarce?
Take a look at the shift to electric cars and I think it's extremely reasonable to suggest that we're never going actually reach that point because we'll stop using it before the point of economic unfeasibility is reached. If tomorrow morning the entire world forever stopped finding new oil resources, I personally have faith that 50 years would be enough time to transition off of it.
I hope so with you. The older I get, the less optimistic I am that we will.
What specifically is it you're concerned we're going to "effectively" run out of?
The means to provide the global population with at least the basic nescessities of survival, needed to keep, or advance our level of civilization. Which is a combination of means to produce, and means to transport.
I fear we can't out-tech our current population growth rate in time to prevent bloody conflicts, and starvations on a scale that makes Ethiopia look like Disneyland.
