Introduction Many researchers‚ scientists‚ and environmentalists are expressing concerns about changes in the overall climate of the earth. Some believe that a dramatically dangerous warming is taking place in the overall global climate‚ a problem that is referred to as "global warming." This paper will attempt to explore this very issue‚ its causes‚ dangerous and somehow deadly effects and how we could deal with this global crisis. Global warming has become perhaps the most complicated issue

economy more reliant on solar energy‚ hydrogen gas‚ wind biomass‚ and other renewable energy sources. The term greenhouse effect is used to describe the increased warming of the Earth’s surface and lower atmosphere due to increased levels of carbon dioxide and other atmospheric gases that absorb radiated energy in the atmosphere and then reradiate it back to the surface. But if it were not for the greenhouse effect‚ temperatures at the Earth’s surface today would be much colder then they are now

increased as the water bath temperature increased. This continues all the way until the water bath of 39°C in which the respiration decreased. There are various reasons that could have caused this to happen‚ such as human error by not placing the carbon dioxide sensor correctly into the respiration chamber or not immersing the respiration chamber as deep into the water bath. Also‚ there could have been a reoccurrence of the possible earlier error of not giving the crickets enough time to acclimate. As

metabolize sugar and gives off carbon dioxide as a by-product. For the second hypothesis‚ we were expecting that yeast will produce a gas when sugar is available. For the third hypothesis‚ we did not expect yeast to produce a gas when no sugar or other food is available. The reason is that carbon dioxide is a product of respiration and is formed when the yeast respires. Therefore‚ when no food and sugar is available‚ respiration cannot take place. Hence‚ no carbon dioxide is formed.

Among the most harmful and dangerous non-metal compunds are nitrogen oxides‚ sulphur dioxide‚ carbon dioxide‚ carbon monoxide‚ and hydrogen sulphide. These can cause devastating effects to human beings‚ plants‚ animals and the environment. Matals are generaly less harmful‚ although lead is extremely toxic. Hydrogen sulphide is a highly toxic gas. It has a very bad smell‚ often identified in rotten eggs and stink bombs. Hydrogen sulphide interferes with cellular respiration. If inhaled‚ Hydrogen

to our environment. The carbon cycle starts off in many different ways‚ fossil fuels‚ respiration‚ and factory emissions. Then as the cycle continues‚ carbon that is transmitted into the oxygen will then be taken in by plants and animals as they intake vegetables and other autotrophic organisms. Then as organisms and waste products die‚ they will start the process of decomposing and begin returning the carbon that they have taken during their lifetime. Without the carbon cycle‚ many of the worldly

With movies such as An Inconvenient Truth‚ the work of political figures such as Al Gore‚ and the increased debate over polar ice caps‚ rising sea levels‚ pollution‚ becoming “Greener‚” oil and gas prices‚ and carbon dioxide‚ global warming is something that most of the world’s population is aware of and concerned with. With an investigation into what global warming is‚ we can begin to understand how we‚ as people‚ are affecting our planet‚ and what it could do to

fast it’s happening. There have been many meetings with other nations to control the amount of carbon-dioxide released. Along with the release of CFC’s that hurt our ozone. The Ozone deflects 99% of the UV rays which cause a variety of disease. We all know that it is bad but because most people don’t know what to do to help their environment. Well it’s the simple things like recycling and reducing your carbon-foot print. All these things if each person contributes we can make a better world not just
