From Wikipedia, the free encyclopedia

The Optimum Population Trust (OPT) is a registered United Kingdom charity, think tank, and campaign group concerned with the impact of population growth on the natural environment, specifically natural resources, climate change and biodiversity. With respect to population growth, it researches climate change, energy requirements, biodiversity, and other environmental factors. OPT campaigns for population stabilisation and gradual decrease both globally and in the United Kingdom. It advocates improved provision of family planning and sex education, better education and rights for women and that couples voluntarily "stop at two". For the UK, it advocates greater effort to reduce the high rates of teenage pregnancy and unintended pregnancy and that immigration is brought into balance with emigration. OPT is funded by its membership and charitable grants.

The OPT believes that an optimal or sustainable population taking into account environmental and resource factors using the ecological footprint approach lies in the following ranges: for the world 2.7 to 5.1 billion; for the UK 17 to 27 million.^[1]

History

The Optimum Population Trust was founded in 1991 by the late David Willey, its first chairman. Its purpose was to collect, analyse and disseminate information about the sizes of global and national populations, and their relations with the carrying capacities of different countries and the quality of life of their inhabitants. It was intended that such information should help people to make informed choices about policies affecting their and their descendants' welfare. Special emphasis was given to the situation in the United Kingdom.

The need for this function was seen in the failure of UK governments to act on the recommendations of the Royal Commission on Population in 1949, the Parliamentary Select Committee on Science and Technology in 1971 and the Government Population Panel in 1973 to set up a mechanism for monitoring and policy guidance on issues affected by population changes - such as welfare, education, labour supply, population ageing, immigration and impact on the environment.

The need was also seen in a general neglect of the role of population pressure by bodies concerned with the relief of poverty and protection of the environment. OPT was granted charitable status on 9 May 2006.
