The depletion of natural resources occurs when resources are consumed at a faster rate than that of replacement.
Exploitation of natural resources
Reckless drilling can be devastating for the environment and local communities. Oil and gas drilling has serious consequences for our wildlands and communities. Drilling projects operate around the clock, disrupting wildlife, water sources, human health, recreation and other aspects of public lands that were set aside and held in trust for the American people. And the consequences could be devastating for the environment and local communities. The pronghorn antelope has one of the longest big game migrations in the U. Oil and gas extraction is a menace to wildlife. The infrastructure built for energy development can also get in the way.

Every one of us is sustained by various kinds of natural resources — such as food, materials, and energy that are harvested or otherwise extracted from the environment. Our need for those resources is absolute — we cannot survive without them. Moreover, the same is true of all other species — every organism is a component of an ecosystem that provides the means of subsistence. Collectively, the needs and activities of people comprise a human economy. That economy operates at various scales, ranging from an individual person, to a family, to communities such as towns and cities, nation-states such as Canada , and ultimately the global human enterprise.
It inevitably generates emissions and other untoward environmental effects across the entire lifecycle of each and every product. Moreover, growing resource scarcity and fluctuating raw materials prices are provoking severe economic disruption and social unrest. The high standard of living that we enjoy here in Germany depends entirely on the availability of natural resources. Apart from abiotic and biotic raw materials, we use water, soil, air, biodiversity and land as habitats and for recreational purposes; and for energy we use wind power, solar power and tidal flows. These resources also serve as emission sinks, waste dumps, and as indispensable production factors for farming and forestry. But unfortunately — and inevitably — resource use across the entire supply chain generates environmental pollution; plus worldwide resource use is growing steadily.
Study Session 1 Human Interactions with the Environment
This article takes a look at the paradoxical ideology that while the impact of technology on the environment has been highly negative, the concept of environmental technology could save our planet from the harm that has been done. This idea is supported by WWF 1 , who have stated that although technology is a solution enabler it is also part of the problem. We are currently living in a period of rapid change, where technological developments are revolutionising the way we live, at the same time as leading us further into the depths of catastrophe in the form of climate change and resource scarcity. Finally it will explore the particular environmental technology of the gas sensor and discuss how it plays a part in the mitigation of negative environmental consequences.
Unit 1 The Earth System and its Components
The exploitation of natural resources is the use of natural resources for economic growth ,  sometimes with a negative connotation of accompanying environmental degradation. It started to emerge on an industrial scale in the 19th century as the extraction and processing of raw materials such as in mining , steam power , and machinery developed much further than it had in preindustrial areas. During the 20th century, energy consumption rapidly increased. Intensive agriculture is an example of a mode of production that hinders many aspects of the natural environment , for example the degradation of forests in a terrestrial ecosystem and water pollution in an aquatic ecosystem. As the world population rises and economic growth occurs, the depletion of natural resources influenced by the unsustainable extraction of raw materials becomes an increasing concern.
To understand the context of the WASH sector you need to understand the nature of the interactions between us as human beings and our environment. Humans need to interact with the environment to obtain our food, water, fuel, medicines, building materials and many other things. Advances in science and technology have helped us to exploit the environment for our benefit, but we have also introduced pollution and caused environmental damage. The impact of environmental problems on humans is significant, affecting all human activities, including health and socio-economic development. In this study session you will learn about the relationships between humans and the environment, and the ways in which we use environmental resources.
What are the consequences of the overexploitation of natural resources? Human beings are depleting the planets natural resources. The uncontrolled consumption of natural resources has significant effects: worldwide breathe air with high levels of pollutants and seven million people die each year air pollution.

The goals for a transition toward sustainability, as we set them out in Chapter 1, are to meet human needs over the next two generations while reducing hunger and poverty and preserving our environmental life support systems. The activities to approach this goal can only move ahead within the constraints set by resources and the environment.
Environment and human beings are inter-related. The environment gives us food, water, fuel, medicines, building materials, etc. Though science and technology have advanced and because of that we have benefitted a lot but it also introduced pollution and damaged the environment. The impact of this is also on human beings like health-related issues and socio-economic development.
One of the most compelling reasons for studying environmental science and management is the fact that, in the view of many leading authorities, we are now experiencing an environmental crisis; indeed, many authors have claimed that the present environmental crisis is unprecedented in its magnitude, pace and severity Park Awareness of this environmental crisis has grown since the s, partly as a result of the prominence given to major so-called 'environmental' disasters such as the Sahelian droughts of the s and s and the nuclear accident at Chernobyl in Consequently, a wide range of environmental problems has emerged; those problems include anthropogenic climate change 'global warming' , the depletion of stratospheric ozone the 'ozone hole' , the acidification of surface waters 'acid rain' , the destruction of tropical forests, the depletion and extinction of species, and the precipitous decline of biodiversity.

Environmental sustainability is one of the biggest issues faced by the mankind at present. Increasing population along with tremendous escalation in anthropogenic activities has raised several questions on the sustainability of natural resources on our planet. No part of the Earth is now untouched by the effect of human activities or pollution.
