environmental problems‚ such as rising levels of atmospheric carbon dioxide‚ global warming‚ and pollution‚ are aggravated by the population expansion. Other problems associated with overpopulation include the increased demand for resources such as fresh water and food‚ starvation and malnutrition‚ consumption of natural resources faster than the rate of regeneration (such as fossil fuels)‚ and a decrease in living conditions. However‚ some believe that waste and over-consumption‚ especially by wealthy

Fresh Water Pollution In the most common usage pollution refers to contamination of water by chemical‚ biological‚ or other harmful substances. Some water pollution laws view the concept much more broadly; the United States Clean Water Act defines pollution as the man made or man induced alteration of chemical‚ physical‚ biological integrity of the nation’s water (Adler‚ n.d.). Common law approaches were created through gradual accumulation of judicial decision in individual cases which set

Fundamental Science Salt water egg experiment Result Some objects float on top of the ocean‚ and other objects sink to the bottom. Why? In this salt water egg experiment we can find a solution for this question. It was noted that to make the egg float salt is needed to dissolve into fresh water. When the egg was lowered into the fresh water container it started to sink. But when salt was added to the container the egg started to float. Adding salt to the water squishes more molecules

IMPORTANCE OF FRESH WATER All living things on Earth need fresh water in order to survive But human beings become ill and may even die if they cannot get pure or clean and are forced to drink polluted water. Human beings can only last 3 day without fresh water. People died of thirst after the cyclone in 1999 because their supply of fresh water from irrigation channels was destroyed form tidal waves. However water is needed for many more purposes e.g. in agriculture and industries‚ but this water does not

Did you know that Salt water and fresh water have very different plant and animal life? There are also a few complex fish that can live in both

Among the soil fauna‚ earthworms have an important role to improve soil texture. The soil texture plays an important role in water holding capacity. Earthworms have an ability to enhance soil characteristics. It contributes to the breakdown of organic matter and release plant nutrients (Edwards and Bohlen‚ 1996). Earthworms are also considered as useful indicator of the health of soil ecosystem (Edwards and Bohlen‚ 1992) as to their role in soil fertility through fragmentation and mixed up the soil

Although drowning restricts one’s breathing‚ drowning in freshwater‚ and drowning in salt water will react in the body in two completely different ways (Helmenstine‚ “Drowning in Freshwater). The simple difference whenever it comes to drowning in salt or fresh water is whether the lungs are filled with a hypertonic or hypotonic solution. When drowning in freshwater‚ the water is considered hypotonic‚ meaning when water enters the cell‚ it triggers them to swell and can even cause them to burst ((Helmenstine
