I often read on these forums many of the general problems facing humanity such as diminishing resources, poverty, environmental/bio diversity loss and over population are debated. These sorts of problems seem to be very difficult to solve with existing systems like the U.N and Treaties between so many diverse nations.
I realize many nations are addressing these problems themselves and some problems like population affect countries to different degrees but to give a an example what if all the developed nations got together used a portion of their GDP and bought the remaining rain forests with the aim of doing nothing just conserving them for the future of humanity under global ownership.
Though it sounds a little "New World Order" is it time we bring in an overarching system of laws that apply to all nations with the aim of beginning to address the problems our civilization faces?
