Exact reserves are not known. Humans are using up their allowance for water, soil, clean air and other resources on Earth each year. By August 2, , humans used more from Nature than the planet could renew within a year.
This is known as the Overshoot Day. In , overshoot day was in November; it was in October by , and September in By , it had reached August. And though it appears to be moving steadily in the wrong direction, scientists agree it has slowed down. In , overshoot day was still in August.
The figure was based on a UN report that calculated the economic value of ecosystems destroyed annually, such as diminished rainfall for crops or polluted air for wildlife ecosystems. The problem has gotten worse as populations and consumption grow faster than the natural world can replace. This had led researchers to predict that by , if nothing changed, mankind would need two planets to sustain its lifestyle. As we come close to that dire prediction, the environmental community must increase its efforts to educate the population on preserving natural resources.
Its capacity to support a thriving diversity of species, humans included, is large but fundamentally limited. Ultimately this loss threatens human well-being. And, it surprisingly shows that 27 countries are importing more than half the water they consume, including the UK, Switzerland, Austria, Norway and the Netherlands. Since the s, indices for terrestrial, freshwater species, marine species, tropical forests, drylands, and grasslands all showed significant declines.
During the same time span, the ecological footprint of humans has nearly doubled. Scientists believe that at that rate, humans would need two planets to provide for their wants in the s. This website uses cookies view the Cookies page in the footer for more info.

More conservative estimates place day zero years from now, while others give us less than 40 years to come up with a solution to this imminent problem. Almost all the studies agree that this is an imminent issue in need of more research. While cutting back our consumption will no doubt be key in fixing the issue, so will learning how to recycle phosphorous - and both will be especially impactful in developing countries.
While the United States was once the leading phosphorous producer globally 30 years ago, India and China now account for over 45 percent of the world's total consumption. In all that time, our practices for mining and consuming this mineral have barely improved. Today, phosphate-enriched chemical mixtures are added to nutrient-starved soil only once before they are swept out to sea.
As of January 1, , there were an estimated 7, trillion cubic feet Tcf of total world proved reserves of gross natural gas [13] From IEA. Last updated: March 8 , However, for the US, the U. Energy Information Administration estimates in the Annual Energy Outlook that as of January 1 there were about 2, trillion cubic feet Tcf of technically recoverable resources TRR of dry natural gas in the United States.
Taking into consideration the current rate of natural gas production and current known natural gas reserves, we have about We will still have gas and coal left by the time oil runs out in But if we increase gas production to fill the energy gap left by oil, then those reserves will only give us an additional eight years, taking us to We should realize that burning gas impacts on global warming because of CO 2 emission.
Global coal demand is up 0. Coal is the oldest fuel we have and it has taken few hundred millions of years to form from vegetation. The US, China and India are still actively mining coal. How long will coal last? It will depend on new technology, may be years in order to replace oil and gas.
According to the IEA, in total global coal consumption in energy terms increased by 1 percent, or Again, China and India lead the increase in consumption.
While the world is gobbling up fossil fuel, we are also developing alternative fuels. The world is actively developing renewable sources of energy — solar, wind and hydro — though the latter is limited because of global warming and overall lack of water.
Global renewable power production increased by 6. The growth rate in is around 75 Million tonnes oil equivalent Mtoe. As fossil fuels begin to disappear, nuclear power is becoming more and more prominent because it is the only alternative base system capable of providing electricity continuously 24 hours a day.
It is carbon-free, vital to our clean energy future.
