Issue Paper Thesis: Driving fast is very dangerous for peoples because it’s causes environment‚ vehicle‚ money‚ society and serious injury or death. Introduction: As a human we all like to drive fast because we think it is fun. But we should know that driving to fast also the third leading contributing factor in traffic crashes. So please now took a minute to think how bad is driving fast for our society and us? I think just by searching in your mind you can find by yourself that speeding could

through the action of sunlight on previously emitted reactive materials. For example‚ ozone‚ a dangerous pollutant in smog‚ is produced by the interaction of hydrocarbons and nitrogen oxides under the influence of sunlight. Ozone has also caused serious crop damage. On the other hand‚ the discovery in the 1980s that air pollutants such as fluorocarbons are causing a loss of ozone from the earth ’s protective ozone layer has caused the phasing out of these materials. Current information about the problem

INTRODUCTION Protection of environment or in other words environment preservations or preventing environment pollution has been a growing concern of the modern times. As time flies by‚ and with the theory of global warming and other environmental issues coming into action‚ protecting the environment is of utmost significance. Every nation has its duty towards protecting their surrounding environment. Protecting environment has become such an issue that nowadays; the perspective of protecting has

The major sources of uncertainty include research and development‚ and market analysis. “Will the substitute product work and would it be working the same?” “Is the ozone problem really directly related to Chlorofluorocarbons‚ or a normal cycle has actually caused these observed recent changes?” Finally‚ “could Du Pont’s efforts really have an effect‚ and how much?” “Is this effect going to bring any profit for the

Atmosphere is a layer consisting of a few gases surrounding the planet earth and is vital for the survival of life on earth. The atmosphere protects earth from abrupt temperature fluctuations from the powerful ultra violet radiation coming from the sun. The atmosphere is made up of nitrogen 78%‚oxygen 21%‚argon 0.9%‚carbon dioxideo0.03% and small amount of trace gases ‚helium ‚neon‚ krypton‚ xenon‚ hydrogen and ozone. In addition‚ there is some amount of water vapour. The atmosphere exists in layer called

ENVIRONMENTAL PROBLEMS BIODIVERSITY LOSS Biodiversity - refers to the number and size of populations in a community; variability of species in an area In general‚ there are three categorical levels of biodiversity: 1. Genetic biodiversity - involves populations‚ individuals‚ chromosomes‚ genes and nucleotides 2. Taxonomic biodiversity - include kingdoms‚ phyla‚ orders‚ families‚ genera‚ species‚ subspecies and populations - for practical reasons‚

There are four major factors when it comes to nature causing climate changes; volcanic eruptions‚ ocean currents‚ earth orbital changes‚ and solar variations. There are three major factors when it comes to humans causing climate changes; transportation‚ deforestation‚ and fossil fuels to generate energy. Volcanic eruptions can cause the climate to change. When a volcano erupts tiny particles called aerosols shoot into the atmosphere. These tiny particles reflect solar energy into space and cool

Chemistry at Work: CO2 and the Greenhouse Effect Greenhouse gases and global warming have received increasing attention in recent years. The identification of the ozone hole in 1985 combined with unusual fluctuations in global temperatures have combined to capture the eye of the global media. Recent scientific study and analysis of the greenhouse gases has added to this interest. Greenhouse gases in the atmosphere have an important influence on the climate of our planet. Quite simply‚ greenhouse
