below 1 percent of total energy consumption‚ compared with roughly 85 percent from oil‚ natural gas‚ and coal. Those fossil fuels cannot remain the dominant sources of energy forever. Whatever the precise timetable for their depletion‚ oil and gas supplies will not keep up with growing energy demands. Coal is available in abundance‚ but its use exacerbates air and water pollution problems‚ and coal contributes even more substantially than the other fossil fuels to the buildup of carbon dioxide in the

approximately 99% of all the liquid fresh water. More than 75% of underground water has a replenishment time of centuries or more‚ making it non-renewable. Increased water withdrawal from underground aquifers makes them more susceptible to droughts. Depletion of ground water may lead to land compaction that in turn decreases its ability to store water. All of the statements about ground water are true. * Instructor Explanation: The answer can be found in Section 5.1 of your text. Question 3. Which

this argument‚ we therefore‚ have a responsibility towards the natural world‚ more specifically towards the natural resources deemed vital for survival. Some of the resources supplied by the natural world that are useful to us include natural gas‚ coal‚ oil‚ land‚ food supplies from plants and many more. Animals are also part of the natural world which should not be forgotten‚ they provide diverse resources‚ which are vital‚ in keeping us alive. The responsibility to take care of these resources

The term pollution can be applied when the composition of something has been modified by the presence of one or more substances that either it cannot be used for a specific purpose or it is less suitable for that use than it was in its natural state.

Abstract Eight global crises – human economy‚ climate change‚ exponential human population growth‚ ecological overshoot‚ biotic impoverishment and the reduction of biodiversity‚ renewable resource depletion‚ energy allocation‚ and environmental refugees – affect each other and affect and are affected by the biosphere. Some‚ perhaps all‚ are close to tipping points that‚ if tipped‚ will result in irreversible change. And yet‚ no sense of urgency is apparent. If any one of the eight interactive crises

resource Some non-renewable resources can be renewable but take an extremely long time to renew. Fossil fuels‚ for example‚ take millions of years to form and so are not practically considered ’renewable’. Different non-renewable resources like oil‚ coal‚ natural gas etc. have different levels of demand from different sectors like transportation and residences with each resource specializing for each sector.[3] Many environmentalists propose a tax on consumption of non renewable resources.
