atmospheric mining

atmospheric mining is the process of extracting valuable materials or other non-renewable resources from the atmosphere. due to the abundance of hydrogen and helium in the outer planets of the solar system, atmospheric mining may be easier than mining terrestrial surfaces.

exploitation of natural resources

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 seven trust materials such as in mining, steam power, and machinery developed much further than it had in preindustrial areas.

list of renewable resources produced and traded by the .

this list of renewable resources produced and traded by the united kingdom presents various renewable resources such as crops for food or fuel, livestock and wood with accompanying information being given on its production and trade by the united kingdom.

renewable energy

renewable energy is energy that is collected from renewable resources, which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. renewable energy often provides energy in four important areas: electricity generation, air and water heating/cooling, transportation, and rural off-grid energy services.

environmental resource management

environmental resource management is the management of the interaction and impact of human societies on the environment.it is not, as the phrase might suggest, the management of the environment itself. environmental resources management aims to ensure that ecosystem services are protected and maintained for future human generations, and also maintain ecosystem integrity through considering .

resource consumption

measures of resource consumption are resource intensity and resource efficiency. industrialization and globalized markets have increased the tendency for overconsumption of resources. the resource consumption rate of a nation does not usually correspond with the primary resource availability, this is called resource curse.

renewable resource

water can be considered a renewable material when carefully controlled usage, treatment, and release are followed. if not, it would become a non-renewable resource at that location. for example, as groundwater is usually removed from an aquifer at a rate much greater than its very slow natural recharge, it is a considered non-renewable resource. removal of water from the pore spaces in .

world energy resources

renewable resources are available each year, unlike non-renewable resources, which are eventually depleted. a simple comparison is a coal mine and a forest. while the forest could be depleted, if it is managed it represents a continuous supply of energy, vs. the coal mine, which once has been exhausted is gone. most of earth's available energy .

material criticality

material criticality is the determination of which materials that flow through an industry or economy are most important to the production process. it is a sub-category within the field of material flow analysis mfa , which is a method to quantitatively analyze the flows of materials used for industrial production in an industry or economy. mfa is a useful tool to assess what impacts .

non-renewable resource

a non-renewable resource also called a finite resource is a natural resource that cannot be readily replaced by natural means at a quick enough pace to keep up with consumption . an example is carbon-based fossil fuel. the original organic matter, with the aid of heat and pressure, becomes a fuel such as oil or gas.

sustainable materials management

sustainable materials management is a systemic approach to using and reusing materials more productively over their entire lifecycles. it represents a change in how a society thinks about the use of natural resources and environmental protection.by looking at a product's entire lifecycle new opportunities can be found to reduce environmental impacts, conserve resources, and reduce costs.

ecological engineering

origins, key concepts, definitions, and applications. ecological engineering emerged as a new idea in the early 1960s, but its definition has taken several decades to refine, its implementation is still undergoing adjustment, and its broader recognition as a new paradigm is relatively recent.

world3 nonrenewable resource sector

the world3 nonrenewable resource sector is the portion of the world3 model that simulates the nonrenewable resources.the world3 model was a simulation of human interaction with the environment designed in the 1970s to predict population and living standards over the course of the next 100 years.

memory barrier

a memory barrier, also known as a membar, memory fence or fence instruction, is a type of barrier instruction that causes a central processing unit cpu or compiler to enforce an ordering constraint on memory operations issued before and after the barrier instruction. this typically means that operations issued prior to the barrier are .

operation active fence

operation active fence is an active and ongoing nato operation to protect the turkish southern border region with syria as part of the ongoing syrian civil war. the arab spring was a wave of uprisings and protests in north africa and the middle east. the first disturbances were in december 2010 in tunisia. however, in march 2011, when the arab .

natural resources engineering

natural resources engineering, the sixth abet accredited environmental engineering program in the united states, is a subset of environmental engineering that applies various branches of science in order to create new technology that aims to protect, maintain, and establish sustainable natural resources. specifically, natural resources engineers are concerned with applying engineering concepts .
