Public housing in the United Kingdom, also known as council housing or social housing, provided the majority of rented accommodation until 2011 when the number of households in private rental housing surpassed the number in social housing. Dwellings built for public or social housing use are built by or for local authorities and known as council houses. Since the 1980s non-profit housing associations became more important and subsequently the term "social housing" became widely used, as technically council housing only refers to housing owned by a local authority, though the terms are largely used interchangeably.
Free-market environmentalism argues that the free market, property rights, and tort law provide the best means of preserving the environment, internalizing pollution costs, and conserving resources. Free-market environmentalists therefore argue that the best way to protect the environment is to clarify and protect property rights. This allows parties to negotiate improvements in environmental quality. It also allows them to use torts to stop environmental harm.
A real estate trend is any consistent pattern or change in the general direction of the real estate industry which, over the course of time, causes a statistically noticeable change. This phenomenon can be a result of the economy, a change in mortgage rates, consumer speculations, or other fundamental and non-fundamental reasons. At one time, all real estate brokers and agents, or Realtors, practiced "single agency", meaning they represented only the buyer or the seller.
