Organized by the forerunner of the United Nations, the League of Nations, and Margaret Sanger; the conference was an attempt to bring together international experts on population, food supply, fertility, migration and health to discuss the problem of human overpopulation. The conference was organized with funds donated by Sanger's husband, J. Noah Slee, as well as a grant from the Rockefeller Foundation. Sir. Bernard Mallet presided over the meeting, and William H. Welch was vice-president. The conference was attended by delegates from all over the world, promoted the study of human population and led to the establishment of the International Union for the Scientific Study of Population.

Population Control
Population control is the practice of artificially maintaining the size of any population. It simply refers to the act of limiting the size of an animal population so that it remains manageable, as opposed to the act of protecting a species from excessive rates of extinction, which is referred to as conservation biology. While many abiotic and biotic factors influence population control, humans are notably influential against animal populations. Whether humans need to hunt animals for nourishment or simply neuter their pets to prevent reproduction from occurring, these activities actively manage populations. Specifically, population control plays an important role in wildlife populations. Based on the species being dealt with, there are numerous ways populations of the wild are controlled. Wildlife contraception is the act of preventing reproduction in the wild, which subsequently decreases populations. An example of this includes the maintenance of deer populations with the use o ...

Hypertension
Hypertension (HTN or HT), also known as high blood pressure (HBP), is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. High blood pressure usually does not cause symptoms. Long-term high blood pressure, however, is a major risk factor for stroke, coronary artery disease, heart failure, atrial fibrillation, peripheral arterial disease, vision loss, chronic kidney disease, and dementia. Hypertension is a major cause of premature death worldwide. High blood pressure is classified as primary (essential) hypertension or secondary hypertension. About 90–95% of cases are primary, defined as high blood pressure due to nonspecific lifestyle and genetic factors. Lifestyle factors that increase the risk include excess salt in the diet, excess body weight, smoking, and alcohol use. The remaining 5–10% of cases are categorized as secondary high blood pressure, defined as high blood pressure due to an identifiable cause, such ...

Tuberculosis
Tuberculosis (TB) is an infectious disease usually caused by '' Mycobacterium tuberculosis'' (MTB) bacteria. Tuberculosis generally affects the lungs, but it can also affect other parts of the body. Most infections show no symptoms, in which case it is known as latent tuberculosis. Around 10% of latent infections progress to active disease which, if left untreated, kill about half of those affected. Typical symptoms of active TB are chronic cough with blood-containing mucus, fever, night sweats, and weight loss. It was historically referred to as consumption due to the weight loss associated with the disease. Infection of other organs can cause a wide range of symptoms. Tuberculosis is spread from one person to the next through the air when people who have active TB in their lungs cough, spit, speak, or sneeze. People with Latent TB do not spread the disease. Active infection occurs more often in people with HIV/AIDS and in those who smoke. Diagnosis of active TB is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Francis Galton
Sir Francis Galton, FRS FRAI (; 16 February 1822 – 17 January 1911), was an English Victorian era polymath: a statistician, sociologist, psychologist, anthropologist, tropical explorer, geographer, inventor, meteorologist, proto-geneticist, psychometrician and a proponent of social Darwinism, eugenics, and scientific racism. He was knighted in 1909. Galton produced over 340 papers and books. He also created the statistical concept of correlation and widely promoted regression toward the mean. He was the first to apply statistical methods to the study of human differences and inheritance of intelligence, and introduced the use of questionnaires and surveys for collecting data on human communities, which he needed for genealogical and biographical works and for his anthropometric studies. He was a pioneer of eugenics, coining the term itself in 1883, and also coined the phrase " nature versus nurture". His book ''Hereditary Genius'' (1869) was the first social sc ...

William Morton Wheeler
William Morton Wheeler (March 19, 1865 – April 19, 1937) was an American entomologist, myrmecologist and Harvard professor. Biography Early life and education William Morton Wheeler was born on March 19, 1865, to parents Julius Morton Wheeler and Caroline Georgiana Wheeler ( Anderson) in Milwaukee, Wisconsin. At a young age, Wheeler had an interest in natural history, first being when he observed a moth ensnared in a spiders web; such observation interested Wheeler that he became importunate for more nature lore. Wheeler attended public school, but, due to "persistently bad behavior", he was transferred to a local University School of Milwaukee, German academy which was known for its extreme discipline. After he completed his courses in the German academy, he attended a German normal school. In both institutions, Wheeler was trained in a variety of subjects: he was given training in languages, philosophy and science. By this time, he could read fluently in French, German, Greek, ...
