The term Womb Tomb (also, womb-tomb) is a form of Neolithic burial site. It is also a generic term for more recent burial sites that are frequented by Christian and Muslim pilgrims. The term has resonance in Christianity where in the creation story of mankind, God tells Adam:" In the sweat of thy face shalt thou eat bread, till thou return unto the ground; for out of it wast thou taken: for dust thou art, and unto dust shalt thou return." (Genesis 3:19); also (Job 1:21). Jewish and other pre-Christian sources have similar references. Europe's prehistory stretches for some 9500 years, from the earliest settlers after the last ice age to around AD 1000. Very little is known of the earliest human burials. The first grave structure of any type dates from circa 4000 BCE. Neolithic farmers had a strong tradition of building burial chambers covered by mounds. Unique burial sites suggest a reverence for birth and the female form. These are called Womb Tombs and are a subset of passage graves or passage tombs. Recent studies show that many of the Neolithic passage graves in Scotland and Ireland were built using the symbolism of the female human womb.

Sustainability is the capacity to endure in a relatively ongoing way across various domains of life. In the 21st century, it refers generally to the capacity for Earth's biosphere and human civilization to co-exist. It is also defined as the process of people maintaining change in a homeostasis-balanced environment, 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 interconnected domains or pillars: environmental, economic and social, which according to Fritjof Capra, is based on the principles of systems thinking. Sub-domains of

Sustainability is the capacity to endure in a relatively ongoing way across various domains of life. In the 21st century, it refers generally to the capacity for Earth's biosphere and human civilization to co-exist. It is also defined as the process of people maintaining change in a homeostasis-balanced environment, 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 interconnected domains or pillars: environmental, economic and social, which according to Fritjof Capra, is based on the principles of systems thinking. Sub-domains of sustainable development have been considered also: cultural, technological and political. According to Our Common Future, sustainable development is defined as development that "meets the needs of the present without compromising the ability of future generations to meet their own needs." Sustainable development may be the organizing principle of sustainability, yet others may view the two terms as paradoxical (seeing development as inherently unsustainable). Sustainability can also be defined as a socio-ecological process characterized by the pursuit of a common ideal. An ideal is by definition unattainable in a given time and space. However, by persistently and dynamically approaching it, the process results in a sustainable system. Many environmentalists and ecologists argue that sustainability is achieved through the balance of species and the resources within their environment. As is typically practiced in natural resource management, the goal is to maintain this equilibrium, available resources must not be depleted faster than resources are naturally generated. Modern use of the term "sustainability" is broad and difficult to define precisely. Originally, "sustainability" meant making only such use of natural, renewable resources that people can continue to rely on their yields in the long term. The concept of sustainability, or Nachhaltigkeit in German, can be traced back to Hans Carl von Carlowitz (1645–1714), and was applied to forestry. "Healthy" ecosystems and environments are necessary for the survival of humans and other organisms. Ways of reducing undesirable human impact may include environmentally-friendly chemical engineering, environmental resources management, environmental protection, and human-population control. Information is gained from green computing, green chemistry, earth science, environmental science, and conservation biology. Ecological economics studies the fields of academic research that aim to address human economies and natural ecosystems. Moving towards sustainability can involve social challenges that entail international and national law, urban planning and transport, supply-chain management, local and individual lifestyles and ethical consumerism. Ways of living more sustainably can take many forms, such as:
* reorganizing living conditions (e.g., ecovillages, eco-municipalities, and sustainable cities)
* reappraising economic sectors (permaculture, green building, sustainable agriculture) or work practices (sustainable architecture)
* using science to develop new technologies (green technologies, renewable energy and sustainable fission and fusion power)
* designing systems in a flexible and reversible manner
* adjusting individual lifestyles to conserve natural resources In sum, "the term 'sustainability' should be viewed as humanity's target goal of human-ecosystem equilibrium (homeostasis), while 'sustainable development' refers to the holistic approach and temporal processes that lead us to the endpoint of sustainability." Despite the increased popularity of the use of the term "sustainability", the possibility that human societies will achieve environmental sustainability has been, and continues to be, questioned—in light of environmental degradation, climate change, overconsumption, population growth and societies' pursuit of unlimited economic growth in a closed system.
