Human growth and development

List of countries by Human Development Index

This is best secured by decentralizing the management of resources upon which local communities defend, and giving these communities an effective say over the use f these resources.

Nevertheless, an amount of electricity equal to the energy used by a person who works all day, burning up 1, calories worth of food, can be bought for less than ten cents Loftness,p.

Scientific American 3 Some large-scale projects, however, require participation on a different basis. Moreover, these figures are optimistic because the demand for energy will not remain at current rates; Human growth and development can be expected to grow at an ever-quickening pace.

In addition, the wealth of wild animals that once sustained hunting societies will be gone, and topsoil that has been spoiled by tractors will yield poorly to the hoe. Carbon dioxide of which there was an abundance in the earth's early atmosphere reacts with water through energy from light, fixing carbon and releasing oxygen, and a portion of the energy remains captive as long as the carbon and the oxygen remain apart.

The evolution of a species like Homo sapiens may be an integral part of the life process, anywhere in the universe it happens to occur. The unity and diversity of life, 4th ed. It is not secreted at a constant rate all day but in small bursts of activity.

This may have been the innovation that let Homo erectus prosper and permitted his species to radiate out of the African cradle, pursuing game throughout the tropics of the Old World Binford,p.

Environmental concern is common to both sides.

About Human Development

Hence the challenge now is to quickly lower population growth rates, especially in regions such as Africa, where these rates are increasing. The ultimate limits to global development are perhaps determined by the availability of energy resources and by the biosphere's capacity to absorb the by-products of energy use.

Hydropower furnishes about 5. Since exploiting a resource always requires energy, the evolution of technology has meant the application of energy to a growing array of substances so that they can be "used to advantage.

The carrying capacity of an entire nation is obvious to no one, particularly if the nation imports large quantities of food from outside its boundaries. From the Big Bang to black holes. This stress, known as population pressure, motivated people to develop additional improvements in agricultural technology, or adopt more productive agricultural practices from neighbouring people.

And it weakens the natural defenses by which organisms fight off disease. The adolescent growth spurt in the female is probably caused by testosterone-like substances androgens secreted by the adrenal gland in both male and female.

The answer could well be no. However, most nations are too large to provide the negative feedback loops between population and carrying capacity that smaller-scale territories provided in the past.

No one can guarantee human happiness, and the choices people make are their own concern. Non-fuel mineral resources appear to pose fewer supply problems.

Six Stages of Human Growth and Development

See Article History Human development, the process of growth and change that takes place between birth and maturity. Some of the new varieties were designed to mature quickly so that farmers could fit more crops into a year. The common theme throughout this strategy for sustainable development is the need to integrate economic and ecological considerations in decision making.

More immediate needs include modifying the pattern of world trade in minerals to allow exporters a higher share in the value added from mineral use, and improving the access of developing countries to mineral supplies, as their demands increase. However, their internally generated population growth was nearly zero by the end of the 20th century.

This made the carrying capacity higher, and the upward cycle of human population continued as a positive feedback loop between population and technology. A library of reports is available here.

Human Ecology - Basic Concepts for Sustainable Development

By the time individuals discover that remaining resources will not be adequate for the next generation, the next generation has already been born.

The answer lies in the fact that many animal populations are below the carrying capacity of their environment. Urbanization is itself part of the development process.

The development of weapons, for example, made it possible to focus somatic energy so as to obtain high-energy foods with much greater efficiency.

If famine were the sole mechanism of collapse, the species might become extinct quite suddenly.Over – all regions and human development groups have made substantial progress.

The global HDI value in wasup about percent from in Across the world, people are living longer, are more educated and have greater livelihood opportunities. Congratulations Stallion Families All FOUR of our schools were graded "A" by the State of Florida.

Human Population History From hunting and gathering to agriculture. The physical and mental abilities of modern humans - and their ecological position in the ecosystem - were formed by several million years of evolution as hunters and gatherers.
