China in particular has long argued that it is too poor to afford the Western luxury of environmental awareness.

China ranks last among 15 nations in its income group (the fifth decile), behind Vietnam. If Colombia, the group's leader, can afford environmental concern, why can't China?

China fares slightly better in protecting its habitat but much worse in measures of industrial ills.

The bat is more closely related to primates.

Bats are fantastic fliers. They are able to truly fly. Bats are the only mammals able to have powered flight.

A bat's body is made for flight. The neck is short, the chest is large and the stomach is narrow. In order to fly a body must have a wide, thin surface. It also needs the power to push through the air.

Though it sounds like a classroom assignment from Hogwarts School of Witchcraft and Wizardry, weather modification programs have been around for more than 50 years.

The problem is there are too many factors that affect the weather, making naturally occurring phenomena difficult to separate from man-made triggers.

"There was no strong scientific base for changing the weather."

A deadly toxin, arsenic is known for its ability to end life.

Since the 1990s, scientists have discovered about 20 species of bizarre bacteria that "breathe" arsenic.

They are typically found in environments where oxygen is scarce and have been forced to survive on whatever strange substance is easily available.

Exposure to arsenic can occur from the environment and food consumption

Arsenic contamination of groundwater has led to a massive epidemic of arsenic poisoning in Bangladesh[32] and neighbouring countries.

Presently 42 major incidents around the world have been reported on groundwater arsenic contamination. It is estimated that approximately 57 million people are drinking groundwater with arsenic concentrations elevated above the World Health Organization's standard of 10 parts per billion. However, a study of cancer rates in Taiwan [33] suggested that significant increases in cancer mortality appear only at levels above 150 parts per billion. The arsenic in the groundwater is of natural origin, and is released from the sediment into the groundwater due to the anoxic conditions of the subsurface.

Scientists have determined that a number of human activities are contributing to global warming by adding excessive amounts of greenhouse gases to the atmosphere. Greenhouse gases such as carbon dioxide accummulate in the atmosphere and trap heat that normally would exit into outer space.

Reasons for Global Warming Global warming can be minimized to a great extent, if we eliminate the causes which are mostly human made. The responsibility of preventing global warming rests both on individual as well as the state. In individual level we can change our practices such as minimize the usage of fossil based fuel, reduce the electricity consumption by using energy efficient appliances. Vehicular pollution can be minimized by using the public transport system. The nucleus goal is to beget the global warming under control by restricting the carbon dioxide release and other heat ensnaring greenhouse gases into the environment. On an average nearly 10000 pounds of carbon dioxide is released per year in significant countries like Canada and US. This can be immediately curtailed by becoming energy efficient. Reducing the usage of oil, coal and gasoline are one of the effective ways of preventing global warming.

Many celebrations and thanksgiving ceremonies were held to show gratitude for the natural blessings that were a part of life. People gave thanks for the beginning of each new year, the time when the maple sap began to flow, the planting and harvesting of the crops, and the ripening of corn, beans, and strawberries, which they celebrated with festivals.

Native people cared about their environment, especially because they depended on it so much.

Hunters asked silent permission from the animals they killed and thanked them for providing food and clothing for the families of the hunters. They hunted in different places so they would not kill too many animals in any area.

For example, some types of water pollution change the color of the water in a lake or stream, whereas other types are less visible, but both can be equally detrimental to the health of humans and nonhuman animals.

For example, 2,000 years ago, when the Romans smelted silver, lead was released into the environment and carried by the wind over long distances; this lead can still be detected in Scandinavian lake sediments.

Relatively few of these new compounds have been thoroughly tested for possible health or environmental effects.

Loosely speaking, behaviorism is an attitude. Strictly speaking, behaviorism is a doctrine

claims that psychology should concern itself with the behavior of organisms

Methodological behaviorism is a normative theory about the scientific conduct of psychology

theory of learning based upon the idea that all behaviors are acquired through conditioning.

Conditioning occurs through interaction with the environment

behavior can be studied in a systematic and observable manner with no consideration of internal mental states.
