Okay, so if we are to follow your line of thinking that we all just need to eat a little less and use a few less resources, how do you propose we motivate society to make the change?
How many more people could the world support before we get to the same position as we are now?
What about the continuing desertification of farmlands?
What about climate change causing crops to fail on a more regular basis these days?
What about the problems of having enough clean drinking water?
What about the ever shrinking areas of virgin land - where will nature get to exist the way it always has?
If you can solve all of the above, then I will agree with you

What you are trying to say is that we are living in a closed system - nothing is gained or lost. This is not entirely true as some water is lost to outer space every year from the outer atmosphere and some space junk makes it through to the surface, but for the most part everything that is on the planet stays here.
The thing is though, we change the state of things i.e Carbon dioixide is stored in the earth's soils and also absorbed by plants and converted back to oxygen. We have changed the balance by creating loads more CO2 than nature would by itself and we are clearing forests at an alarming rate to this very day.
We humans are burning off millions of years worth of fossil fuels in less than a century and these are not self replenishing, we are clearing forest lands and destroying natural ecosystems for our farming, we are building immense 'hives' with our megacities that pour mega amounts of pollution into the air.
And these are just a couple of examples of the way we humans are altering the natural order of the planet.
So, here's the crux of the argument - you could fit trillions of us here on the planet if you are just talking about physical space. But the planet's resources would not support it because we need to eat.

There are actually methods in use in China, Yemen, and several other regions where desertified farmland and other land suitable for agricultural use, has been bought back from being desert, into verdant, flourishing greenspace. Normally the problem is over grazing and over farming. The solution is to plant certain plants which just by being there, improve the soil quality, retain moisture beneath the ground, and so on. I will not pretend that these methods are fast, but they are effective, and they are in use as we speak. They are not well publicised, probably because of the massive lobby power of the green bloc, who have more clout the closer people think we are to extinction, and the total destruction of our ability to farm and to live.
Speaking at Greenhouse 2007, CSIRO’s Dr Wenju Cai said the latest modelling by the Intergovernmental Panel on Climate Change (IPCC) showed a 5 to 15 per cent rainfall decrease by 2070.
Given that volcanic erruptions make our contribution to carbon and greenhouse levels in the atmosphere seem utterly insignificant, this is a problem that would be coming about with, or without industry and technology, so no amount of greed and consumerism is going to make a vast difference to wether a crop fails, except in terms of how abused the land itself is, by the aggressive agricultural methods practiced upon it. Other than that, we are at the whim of nature, as we should be. We have no business surviving anything, if we cannot survive that, since a failiure to survive that is the boot of Darwin being placed firmly upon our fundaments, and rightly so.

To a certain extent this is true, Western society is greedy and wasteful, but a large part of the world (think of Africa and parts of the Middle East) goes to bed hungry at night. If we were to change our ways, everyone on the planet would be well fed.

The point I am trying to make is that if we all change our ways, it will slow down the inevitable, but as the population continues to rise, demand will eventually outstrip supply of food and resources.
Countries like China, Japan and Indonesia already have one and 2 child policies in order to curb their population growth. These nations have seen the writing on the wall a long time ago. Eventually we in the west will catch up with them.

We are overpopulated and wasteful. We cannot expect the population to grow and still expect enough land, water, and natural resources to sustain us.
Even if people reverted back to the basic staples such as grain, rice, and water, the growing population would still require more land for sowing and housing.
And water is becoming scarce as well. Rich people are investing in water because it's a finite resource and we are consuming more of it than nature is producing it.
I agree with Stephen Hawking: expand or die.
