Thoughts on Air Pollution Essay

Air pollution Every day, the average person inhales about 20,000 liters of air. Every time we breathe, we risk inhaling dangerous chemicals that have found their way into the air. Air pollution includes all contaminants found in the atmosphere. These dangerous substances can be either in the form of gases or particles. Air pollution can be found both outdoors and indoors. Pollutants can be trapped inside buildings, causing indoor pollution that lasts for a long time. The sources of air pollution are both natural and human-based. As one might expect, humans have...

Drugs and how they affect your health.

In the U.S., 66.5 million people, or about 29 percent of the population, use tobacco. With each puff of a cigarette, a smoker pulls nicotine into his or her lungs where it is absorbed into the blood. In eight seconds, nicotine is in the brain, changing the way the brain works. This process happens so fast because nicotine is shaped like the natural brain chemical acetylcholine. Acetylcholine is one of many chemicals called neurotransmitters that carry messages between brain cells. Neurons have special spaces called receptors, into which specific neurotransmitters can fit, like a key fitting into a lock. Nicotine locks into acetylcholine receptors in different parts of the brain, rapidly causing changes in the body and brain. Nicotine raises the heart rate and respiration (breathing) rate, and causes more glucose, or blood sugar, to be released into the blood. This might be why smokers feel more alert after...

Environment

The ozone layer around the Earth, there is a special type of oxygen called ,,ozone". Ozone is important because it stops ultraviolett radiation from the sun. Many aerosol sprays and factories destroy ozone and they have made a very big hole in the ozone layer. This means that too much ultraviolet radiation now enters the Earth. This is very dangerous because it can cause cancer. Poisonous chemicals also cause acid rain, that destroyes plants, rivers, lakes and buildings. Acid rain can travel thousands of miles, so pollution in one country can become acid rain for another country. So how to avoid the worst? Lets talk about cars, which are the main means of transport in our everyday life, they are useful and take us to the place, where we want to go. But lets be honest, they have also negative aspects.

Physiologic responses to environmental signals include regulations of the nervous system, endocrine organs, and the cardiovascular, respiratory, digestive and excretory functions. During pregnancy, the parent's perception of the environment is chemically communicated to the fetus through the placenta, the cellular barrier between the maternal and fetal blood. The mother's blood-borne emotional chemicals cross the placenta and effect the same target cells in the fetus as those in the parent. Though the developing child is "unaware" of the details (i.e., the stories) evoking the mother's emotional response, they are aware of the emotion's physiological consequences and sensations. While developing in the safety and confinement of the uterus, the child is provided a preview of the environment as it is defined by the parent's perception and behavior. Parental behaviors...
