There have been calls for developed countries to levy taxes on their citizens to pay for the conservation of global commons and possibly some developing country environmental management; Cairncross (1991: 71) estimated that a levy of US $8.00 per person in rich nations would adequately pay for Amazonian protection, and the region is of worldwide value. If it is handled in a skilful way with careful marketing the world’s richer citizens would probably willingly pay much more for environmental management beyond their own borders than is presently the case; the key is to convince people that they ultimately benefit and have a moral duty. There may be other sources of environmental management funding, in the form of ‘international levies’. For example, a charge could be made for communication satellites and distributed to developing countries for environmental care; all intercountry gold exchanges could be subject to a charge to be distributed by the UN.
