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.

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. Then, we review the consequences and possible solutions to this problem.
Human beings are depleting the planet's natural resources. There are two types of natural resources: renewable and non-renewable. The former are inexhaustible, like solar radiation, or their renewal is relatively rapid, as is the case with biomass. Non-renewable resources are those that exist in nature in a limited way because their regeneration involves the passage of many years, such as minerals and fossil fuels — oil, natural gas and coal —.
Human beings are depleting the planet's natural resources and standards of living will begin to decline by unless immediate action is taken. Thus, if we continue at this rate, we would need 2. The disappearance of habitats essential for flora and fauna and, therefore, the extinction of species. There are some 30 million different animal and plant species in the world, and of these, the International Union for Conservation of Nature IUCN says that, currently, more than 31, species are threatened with extinction.
If the erosion of fertile soil continues at the same rate, agricultural commodity prices will inevitably soar. If we do not take care of the forests there will be fewer CO 2 Nota sinks and therefore more air pollution.
According to the World Health Organization WHO , nine out of ten people worldwide breathe air with high levels of pollutants and seven million people die each year air pollution. The future, as stated in the United Nations Agenda for Sustainable Development , poses a double challenge to human beings: conserving the many forms and functions of nature and creating an equitable home for people on a finite planet. If we want to reverse this situation, we need, among other things, to:.

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.

Fossil-fuel dominated electricity generation in the United States and China has enormous environmental consequences. In , 2. In the same year, electricity generation in China produced just over 2 billion metric tons of CO 2 , accounting for about one-third of its energy-related GHG emissions.
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.
Chapter 1 ~ Ecosystems and Humans
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.
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.
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. The social, environmental, and economical problems can be omitted by use of renewable energy sources, because these resources are considered as environment-friendly, having no or little emission of exhaust and poisonous gases like carbon dioxide, carbon monooxide, sulfur dioxide, etc. Renewable energy is going to be an important source for power generation in near future, because we can use these resources again and again to produce useful energy. Wind power generation is considered as having lowest water consumption, lowest relative greenhouse gas emission, and most favorable social impacts.

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. 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.
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.
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.
