Natural resources are those that the planet offers without the need for human intervention. They are essential our survival, but if they are consumed at a faster rate than their natural regeneration, as is currently the case, they can be exhausted.

Social, Economic, and Environmental Impacts of Renewable Energy Resources

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. Ever increasing human population and increment in per capita consumption has put great constraint on the natural resources. In addition to this, urbanization, industrialization and modern agricultural practices have polluted the water resources, air and soil all around the globe. The natural resources are thus not only being over-exploited but also becoming contaminated with toxic chemicals making it difficult for the survival of future generations.

The exploitation of natural resources is the use of natural resources for economic growth , [1] 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. Natural resources are not limitless, and the following consequences can arise from the careless and excessive consumption of these resources:. When a mining company enters a developing country in the global south to extract raw materials, advocating the advantages of the industry's presence and minimizing the potential negative effects gain cooperation of the local people.

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.

Exploitation of natural resources

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. Further, to this, we will study the relationships between human beings and the environment and how we use environmental resources.

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. Yet, while all of these problems have physical environmental manifestations, their causes - and their potential solutions - are invariably bound up with human attitudes, beliefs, values, needs, desires, expectations, and behaviours. Thus the symptoms of the environmental crisis cannot be regarded purely as physical problems requiring solutions by environmental 'specialists'; instead, they are intrinsically human problems and they are intimately related to the question of what it means to be human. At this point, a very brief overview of the environmental crisis may be helpful. It is important to emphasise that a wide range of views about the nature and severity of the current environmental crisis exists, and some of the issues are highly controversial.

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. In this chapter, we therefore ask two related questions:. Rather, it is to highlight some of the most serious environmental obstacles that might be met in plausible efforts to reach the goals outlined in Chapter 1 and along development paths such as those explored in Chapters 2 and 3, to take timely steps to avoid or circumvent these obstacles.

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.

Overall, at least 1. And yet, the electricity required for people to read at night, pump a minimal amount of drinking water and listen to radio broadcasts would amount to less than 1 percent of overall global energy demand. Developing and emerging economies face thus a two-fold energy challenge in the 21st century: Meeting the needs of billions of people who still lack access to basic, modern energy services while simultaneously participating in a global transition to clean, low-carbon energy systems. And historic rates of progress toward increased efficiency, de-carbonization, greater fuel diversity and lower pollutant emissions need to be greatly accelerated in order to do so. To a significant extent, fortunately, the goal of reducing greenhouse gas emissions may be aligned with the pursuit of other energy-related objectives, such as developing indigenous renewable resources and reducing local forms of pollution.

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. The way we use resources provokes often irreversible ecological change.

7 ways oil and gas drilling is bad for the environment

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.

Conventional energy source based on coal, gas, and oil are very much helpful for the improvement in the economy of a country, but on the other hand, some bad impacts of these resources in the environment have bound us to use these resources within some limit and turned our thinking toward the renewable energy resources.
