Water is also present in the atmosphere in solid form in the polar icecaps and as groundwater in aquifers water-bearing rocks deep underground. Water has many remarkable properties. It also acts as a fluid medium facilitating the dispersal of un-dissolved particulate matter.
Sustainable development The name sustainability is derived from the Latin sustinere tenere, to hold; sub, under. Sustain can mean "maintain", "support", or "endure". Components[ edit ] Three dimensions of sustainability[ edit ] A diagram indicating the relationship between the "three pillars of sustainability", in which both economy and society are constrained by environmental limits  Venn diagram of sustainable development: One such pillar is future generations, which emphasizes the long-term thinking associated with sustainability.
A study from pointed out that environmental justice is as important as sustainable development. The simple definition that sustainability is something that improves "the quality of human life while living within the carrying capacity of supporting eco-systems",  though vague, conveys the idea of sustainability having quantifiable limits.
But sustainability is also a call to action, a task in progress or "journey" and therefore a political process, so some definitions set out common goals and values.
This suggested a more complex figure of sustainability, which included the importance of the domain of 'politics'.
More than that, sustainability implies responsible and proactive decision-making and innovation that minimizes negative impact and maintains balance between ecological resilience, economic prosperity, political justice and cultural vibrancy to ensure a desirable planet for all species now and in the future.
More recently, using a systematic domain model that responds to the debates over the last decade, the Circles of Sustainability approach distinguished four domains of economic, ecological, political and cultural sustainability ;  this in accord with the United NationsUnescoAgenda 21and in particular the Agenda 21 for culture which specifies culture as the fourth domain of sustainable water pollution essays for students.
Rather, it involves treating all four domains—economy, ecology, politics and culture—as social including economics and distinguishing between ecology as the intersection of the human and natural worlds and environment as that which goes far beyond what we as humans can ever know.
Human sustainability can be achieved by attaining sustainability in all levels of the seven modalities. Shaping the future[ edit ] Integral elements of sustainability are research and innovation activities.
A telling example is the European environmental research and innovation policy. It aims at defining and implementing a transformative agenda to greening the economy and the society as a whole so to make them sustainable. Research and innovation in Europe are financially supported by the programme Horizonwhich is also open to participation worldwide.
Additionally, instigating innovative and sustainable travel and transportation solutions must play a vital role in this process. Resilience-thinking evolved from the need to manage interactions between human-constructed systems and natural ecosystems in a sustainable way despite the fact that to policymakers a definition remains elusive.
Resilience-thinking addresses how much planetary ecological systems can withstand assault from human disturbances and still deliver the service's current and future generations need from them.
It is also concerned with commitment from geopolitical policymakers to promote and manage essential planetary ecological resources in order to promote resilience and achieve sustainability of these essential resources for benefit of future generations of life?
In nature, the accounting occurs naturally through a process of adaptation as an ecosystem returns to viability from an external disturbance.
The adaptation is a multi-stage process that begins with the disturbance event earthquake, volcanic eruption, hurricane, tornado, flood, or thunderstormfollowed by absorptionutilizationor deflection of the energy or energies that the external forces created.
History of sustainability The history of sustainability traces human-dominated ecological systems from the earliest civilizations to the present day. Coal was used to power ever more efficient engines and later to generate electricity. Modern sanitation systems and advances in medicine protected large populations from disease.
In the late 20th century, environmental problems became global in scale. In the 21st century, there is increasing global awareness of the threat posed by the human greenhouse effectproduced largely by forest clearing and the burning of fossil fuels.
The focus ranges from the total carrying capacity sustainability of planet Earth to the sustainability of economic sectors, ecosystems, countries, municipalities, neighbourhoods, home gardens, individual lives, individual goods and services[ clarification needed ], occupations, lifestyles, behaviour patterns and so on.
In short, it can entail the full compass of biological and human activity or any part of it. To shed light on the big picture, explorer and sustainability campaigner Jason Lewis has drawn parallels to other, more tangible closed systems.
The environmental impact of a community or of humankind as a whole depends both on population and impact per person, which in turn depends in complex ways on what resources are being used, whether or not those resources are renewable, and the scale of the human activity relative to the carrying capacity of the ecosystems involved.
Careful resource management can be applied at many scales, from economic sectors like agriculture, manufacturing and industry, to work organizations, the consumption patterns of households and individuals and to the resource demands of individual goods and services.
This formulation attempts to explain human consumption in terms of three components: The equation is expressed: The most prominent among these concepts might be the Circular Economywith its comprehensive support by the Chinese and the European Union.
There is also a broad range of similar concepts or schools of thought, including cradle-to-cradle laws of ecology, looped and performance economy, regenerative design, industrial ecology, biomimicry, and the blue economy.Find essays and research papers on Economics at leslutinsduphoenix.com We've helped millions of students since Join the world's largest study community.
Sustainability is the process of maintaining change in a balanced fashion, in which the exploitation of resources, the direction of investments, the orientation of technological development and institutional change are all in harmony and enhance both current and future potential to meet human needs and aspirations.
For many in the field, sustainability is defined through the following. Among the most compelling environmental issues of today and tomorrow are those concerning the world's fresh water resources. Peter H. Gleick's important new volume, Water in Crisis, addresses the timely and sometimes controversial aspects of world water leslutinsduphoenix.com stake are water quality, quantity, and possible future conflicts over shared international water resources.
