Hydrogen economyThe hydrogen economy uses hydrogen to decarbonize economic sectors which are hard to electrify, essentially, the "hard-to-abate" sectors such as cement, steel, long-haul transport, etc. In order to phase out fossil fuels and limit climate change, hydrogen can be created from water using renewable sources such as wind and solar, and its combustion only releases water vapor into the atmosphere. Although with a very low volumetric energy density hydrogen is an energetic fuel, frequently used as rocket fuel, but numerous technical challenges prevent the creation of a large-scale hydrogen economy.

Consumers' co-operativeA consumers' co-operative is an enterprise owned by consumers and managed democratically and that aims at fulfilling the needs and aspirations of its members. Such co-operatives operate within the market system, independently of the state, as a form of mutual aid, oriented toward service rather than pecuniary profit. Consumers' cooperatives often take the form of retail outlets owned and operated by their consumers, such as food co-ops.
Environmental educationEnvironmental education (EE) refers to organized efforts to teach how natural environments function, and particularly, how human beings can manage behavior and ecosystems to live sustainably. It is a multi-disciplinary field integrating disciplines such as biology, chemistry, physics, ecology, earth science, atmospheric science, mathematics, and geography. The United Nations Educational, Scientific and Cultural Organization (UNESCO) states that EE is vital in imparting an inherent respect for nature among society and in enhancing public environmental awareness.
Health services researchHealth services research (HSR) became a burgeoning field in North America in the 1960s, when scientific information and policy deliberation began to coalesce. Sometimes also referred to as health systems research or health policy and systems research (HPSR), HSR is a multidisciplinary scientific field that examines how people get access to health care practitioners and health care services, how much care costs, and what happens to patients as a result of this care.
Shanty townA shanty town, squatter area or squatter settlement is a settlement of improvised buildings known as shanties or shacks, typically made of materials such as mud and wood. A typical shanty town is squatted and in the beginning lacks adequate infrastructure, including proper sanitation, safe water supply, electricity and street drainage. Over time, shanty towns can develop their infrastructure and even change into middle class neighbourhoods. They can be small informal settlements or they can house millions of people.
History of the cooperative movementThe history of the cooperative movement concerns the origins and history of cooperatives across the world. Although cooperative arrangements, such as mutual insurance, and principles of cooperation existed long before, the cooperative movement began with the application of cooperative principles to business organization. The cooperative movement began in Europe in the 19th century, primarily in Britain and France. The industrial revolution and the increasing mechanisation of the economy transformed society and threatened the livelihoods of many workers.
Environmental planningEnvironmental planning is the process of facilitating decision making to carry out land development with the consideration given to the natural environment, social, political, economic and governance factors and provides a holistic framework to achieve sustainable outcomes. A major goal of environmental planning is to create sustainable communities, which aim to conserve and protect undeveloped land. Environmental planning concerns itself with the decision making processes where they are required for managing relationships that exist within and between natural systems and human systems.
Transmutation of speciesTransmutation of species and transformism are unproven 18th and 19th-century evolutionary ideas about the change of one species into another that preceded Charles Darwin's theory of natural selection. The French Transformisme was a term used by Jean Baptiste Lamarck in 1809 for his theory, and other 18th and 19th century proponents of pre-Darwinian evolutionary ideas included Denis Diderot, Étienne Geoffroy Saint-Hilaire, Erasmus Darwin, Robert Grant, and Robert Chambers, the anonymous author of the book Vestiges of the Natural History of Creation.
