"Nature provides a free lunch as long as we can control our appetites.
Nature may provide, but it isn't destined for us & our appetites are as unsatiable as our desire to breed.

Quite right, the issue of logging is destroying a collective part of our planet, which in turn hinders a forest's ability to decrease the damage of Co2 on the outer layer, so it could be argued that some parts of the world are a little "too hungry" in terms of taking from nature
Not sure about the 'free lunch' bit. Nature provides, whether wild or farmed, but it isn't free. Look at the effort that goes into farming. Even all of the discussion around foraged food, which is usually perceived as free, involves a cost in terms of time gathering, travel to your foraging location, and the time spent gaining the knowledge to know what you can forage and where to find it.
I have collected a huge quantity of chestnuts today, more than I ever have before, but I had to take the car to get to the site, spend a long time actually collecting the things (back-aching work, not to mention the scratches and prickles that are inevitable in any forage), and then get home again. If I'd bought the same from a shop it would cost me money, but would have been much quicker and less painful, and I would have had the time to do something else instead.
I think it is about choosing which costs you want to pay.
Agreed Rmbriar, some parts of the world are a little "too hungry". With regard to logging though, we (the developed peoples of the world) chopped our forests ages ago and took advantage of these resources. Who are we now to tell developing countries not to do as we have done?
There needs to be an alternative for these peoples available whereby they recieve some reward for maintaining these globally relevant forests for the entire planet.
This reward needs to come from us!
From an academic point of view, why not take 0.64 acres of the most profitable wood /farmland you can find and each day write in a diary what you could take from that patch to keep yourself alive, forget water, just food. you wouldn't need to actually take anything, but only list what is actually found in that plot , nothing more. your not allowed to introduce fertilisers, pesticides, etc just what is in the plot each day you visit, calculate based on a daily average in calories and see if the sheets balance. would be an interesting experiment, and topic for your talk
