 Everyone knows that many of the Earth's resources are finite. We are currently completely reliant on fossil fuels, iron and other metals, minerals and even such basic commodities as sand to keep the modern world ticking over. Adding more consumers makes those resources run out faster. The Earth also provides for our needs with renewable resources, such as timber, clean water and air, healthy soils and wild fish consumed for food. However, our demands are so great that according to the Global Footprint Network, we are now using those resources at almost twice the rate that the Earth can renew them. That rate has increased continually since the 1970s and, unless thing change, we will require three Earths to supply our needs by 2050.
