Scheme of sustainable development: at the confluence of three preoccupations. Clickable.
Sustainable development has been defined as balancing the fulfillment of human needs with the protection of the natural environment so that these needs can be met not only in the present, but in the indefinite future. The term was used by the Brundtland Commission which coined what has become the most often-quoted definition of sustainable development as development that "meets the needs of the present without compromising the ability of future generations to meet their own needs."
The field of sustainable development can be conceptually divided into four general dimensions: social, economic, environmental and institutional. The first three dimensions address key principles of sustainability, while the final dimension addresses key institutional policy and capacity issues.
The Human Development Index (HDI) is a comparative measure of life expectancy, literacy, education, and standard of living for countries worldwide. It is a standard means of measuring well-being, especially child welfare. It is used to determine and indicate whether a country is a developed, developing, or underdeveloped country and also to measure the impact of economic policies on quality of life. The index was developed in 1990 by Indian Nobel prize winner Amartya Sen, Pakistani economist Mahbub ul Haq, with help from Gustav Ranis of Yale University and Lord Meghnad Desai of the London School of Economics and has been used since then by the United Nations Development Programme in its annual Human Development Report.
The HDI measures the average achievements in a country in three basic dimensions of human development: a long and healthy life, as measured by life expectancy at birth; knowledge, as measured by the adult literacy rate (with two-thirds weight) and the combined primary, secondary, and tertiary gross enrollment ratio (with one-third weight); and a decent standard of living, as measured by the log of gross domestic product (GDP) per capita at purchasing power parity (PPP) in USD.
Rachel Louise Carson ( May 27, 1907 — April 14, 1964) was an American marine biologist whose landmark book, Silent Spring, is often credited with having launched the global environmental movement. Silent Spring had an immense effect in the United States, where it spurred a reversal in national pesticide policy. The Rachel Carson Prize is awarded to women who have made a contribution in the field of environmental protection. She was posthumously awarded the Presidential Medal of Freedom.
Starting in the mid-1940s, Carson became concerned about the use of newly invented pesticides, especially DDT. Silent Spring focused on the environment, and pesticides in particular. It was known as Carson's crusade, and she worked on this book till her death. Carson explored the subject of environmental connectedness: although a pesticide is aimed at eliminating one organism, its effects are felt throughout the food chain, and what was intended to poison an insect ends up poisoning larger animals and humans. Carson has been criticized by some conservatives, who argue that restrictions placed on DDT have caused needless malaria deaths.

I went to the woods because I wished to live deliberately, to front only the essential facts of life, and see if I could not learn what it had to teach, and not, when I came to die, discover that I had not lived.
