Are worldwide natural resources reaching THE limit?

I just don't know for sure.  But, in the meantime many people who are currently doing extensive research and environmental assessment seems to think so.  If we google-map the world nowadays and compare the pictures against those taken in the 60s and 70s, it is highly remarkable the strong difference shown by the reduction of green areas all throughout the whole globe. The human race for the span of the wave of consumism released since the late 70s has practically predated most of the resources that Nature had provided for every living creature to survive.  The deforestation of the Amazon Jungle is the most pathetic example of how much we have lost due to our intense and voracious comsumptioness. But, it's not the time and this is not the place to weep and yell for the lost paradise.  We can ammend.  But, we have to start right now.  Let's assume our role: we are the most intelligent creatures ever.  Let's show how smart we can be.

I throw a proposal, not the air, to YOU, please consider this when you look at your young children, they have the right to live in a safe, healthy place, don't forget it:
1.- Let's recycle. Did you know that many trees are destroyed to turn them into clean sheets of paper?  Well, now you know.  If you use (and reuse) the same sheet of paper in a wise manner, then maybe you're helping to save one or two trees, maybe more.
2.- Let's buy our books in a digital format, or if we are compelled to buy a printed one, then try to purchase a book that is made of recycled paper.  Please, our grandchildren will thank you.
3.- Don't spend water in a spoily, irresponsible way.  Are you used to wash your car in the old fashion style?  Don't.  Do it with a bucket of water and a sponge.  Use a shower to take a bath.  Please, do everything you can to reduce your water consumption (but don't stop taking a shower daily).  The fresh water won't last forever if keep on wasting it.
4.- Use public transportation whenever possible.  To go-and-return from work, consider using the public transport, such as the subway, autobus or the like.  That way you will reduce the consumption of fuels.  Remember that among our main concerns nowadays is the topic of Global Warming.  If we don't stop the emissions of CO due to excessive combustion, we will inherit our descendants an earth with about 30% of the current living species in a museum, just for the fossile record.  Not to tell that the temperature will be higher, and many of our cities will be underwater for the time my first grandchild gets born.
5.- Let's grow more trees.  A simple tree (or plant, whatever the like) can help to purify thousands of cubic meters of air per year.  The more plants that we have, the healthier our enviroment will be. It's easy to follow.  We can. Most of all, we MUST. 
Remember that sooner or later we'll be dead, but our children and the children of them will pursue their fate on a planet that will be shaped the way we decide TODAY.
