The increasing worldwide competition for natural resourceswill potentially lead to serious conflicts related to access toresources. These conflicts will mainly affect those peoplewho are not currently involved in the race for resourcesand therefore do not significantly contribute to the overallproblem: the poorest inhabitants of developing countries.Overuse of capacities of global ecosystems. Whetherfurther economic growth and increased consumption ofresources will be possible is also determined by a secondcrucial factor: the limited capacity of the global ecosystemsto provide us with biotic resources, such as cereals,fish and timber, and to absorb the waste and emissions wegenerate through our resource use. This capacity is called“biocapacity”.Calculations using “Ecological Footprint” illustrate that theworld is already using around 30% more biocapacity than theglobal ecosystems can provide in a sustainable manner. 43The Ecological Footprint warns us that with our currentlevel of resource consumption, we are already overusingthe biological capacities of the global ecosystems. In otherwords: we are liquidating the “natural capital” of the planet,instead of living on the sustainable interest from this capital.This depletion of natural capital can be observed inseveral ways: many fish stocks are depleted, worldforests are shrinking, fertile land is being lost due to erosionand carbon emissions are causing changes to the climatewith potentially disastrous impacts on our economiesand societies.Figure 15: Distribution of global reserves of selected materials, 2005 (xiv)28 | OVERCONSUMPTION?
