How much natural resources are left

On the one hand there is our ecological footprint, which includes the spewing out of greenhouse gases -- then there is the capacity of the earth's ecosystems to absorb our waste products and renew ones we have consumed, such as wood from cut down trees in forests. Global Footprint Network estimates it was December 29th in , November 4th in , October 11th in , September 23rd in and August 7th in Design and manage compact and integrated cities with efficient buildings to reduce transport needs.

Improve food production and distribution. Shift consumption habits by deemphasizing animal-based products. Encourage smaller families. Here are six already under severe pressure from current rates of consumption: 1. Water Freshwater only makes 2. Oil The fear of reaching peak oil continues to haunt the oil industry. Natural gas A similar picture to oil exists for natural gas, with enough gas in proven reserves to meet Phosphorus Without this element, plants cannot grow.

Coal This has the largest reserves left of all the fossil fuels, but as China and other developing countries continue to increase their appetite for coal, demand could finally outstrip supply.

According to U. This is the second-highest natural gas reserves total after the record high of The dry natural gas portion of these reserves after removal of HGL is about Click to enlarge.

In addition to the proved natural gas reserves, large volumes of natural gas are classified as undiscovered —or unproved — technically recoverable resources TRR. Undiscovered TRR are expected to exist because the geologic settings are favorable despite the uncertainty of their specific locations.

Undiscovered TRR are also assumed to be producible over a time period using existing recovery technology. Natural gas explained How much natural gas is left. What is energy? Units and calculators. Use of energy. Energy and the environment.
