Indeed, not only could we all not fit into Texas for any period of time, but also we don’t really fit into Earth. To be sustainable, with our current population and level of consumption, we would need 1.7 times the land area available to us. We have overdrawn on our global savings account in order to enjoy our consumptive lifestyle.
We can already see the effects of overpopulation and overconsumption. Perhaps most evident is climate change. Land is eroding, fisheries are depleted and toxic chemicals are ubiquitous. Furthermore, we are killing off other species at terrifying rates – at least 1,000 times normal. Although the Ecological Footprint is an excellent tool for comparing what people are using with what is available, it has a major limitation. It does not leave any resources for other species.
