Global Warming - Killing her softly with our selfishness

Extracts from this document...

Introduction

Global Warming is the increase in the Earth's average temperature, which in turn causes changes in the climate. A warmer Earth may lead to changes in rainfall patterns, a rise in sea level, and it may have an effect on plants, wildlife and even humans. Scientists say that global warming is caused by us humans by using too much of carbon dioxide in our daily routine. At this very point in time every single person is doing there bit to destroy our world! So what is Global warming? Greenhouse gases keep our planet warm. They exist naturally in the atmosphere, heating it by trapping energy that has originally come from the Sun. This process is called the natural greenhouse effect. Without the greenhouse gases the surface of the Earth would be as cold as the surface of the Moon, about -18�C. In fact the average surface temperature of the Earth is about 15�C. Measurements taken from all over the world however, have shown that the global climate is changing. In the last 100 years the atmosphere has warmed up by over half a degree Celsius (�C). Also during this time humans have been releasing extra greenhouse gases, which are the result of burning fossil fuels (like coal, oil and gas). These gases include carbon dioxide, methane and nitrous oxide. It is thought that the man-made emissions of greenhouse gases, from the increased use of fossil fuels, are responsible for some of the global warming during the 20th century. ...read more.

The world's use of transport contributes a lot to Global warming. So how does this actually affect the world? * Human Health- Climate change can occur; Climate change may affect people's health. For example, heat stress and other heat related health problems are caused directly by very warm temperatures and high humidity. Untreated, heat stress can be a very serious medical problem. Scientists suspect that, in many places, global warming will increase the number of very hot days that occur during the year. More hot days increases the possibility of heat related health problems. Ecological disturbances, air pollution, changes in food and water supplies, and coastal flooding are all examples of possible impacts that might affect human health. Especially increasing pollution effecting people who suffer from asthma. Disease causing insects are migrating into latitudes and altitudes never before infested including the U.S. There are about 60 million more cases of malaria every year. * Ecological systems- Climate change may adjust the world's habitats and ecosystems. Animals may not be able to live in extremely; all living things are included in and rely on these places. Many of these places depend on a delicate balance of rainfall, temperature, and soil type. A rapid change in climate could upset this balance and seriously endanger many living things. Most past climate changes occurred slowly, allowing plants and animals to adapt to the new environment or move somewhere else. ...read more.

Conclusion

So the government should possibly improve public transport and increase oil prices. We can Save Electricity, whenever we use electricity we help put greenhouse gases into the air. By turning off lights, the television, and the computer when you are finished with them, can help a lot and we can buy energy saving goods. For example energy saving light bulbs. Many things, like computers, TVs, stereos, and VCRs, have special labels on them. The label says "Energy" and has a picture of a star. Products with the energy star label are made to save energy. Buying products with energy star labels will help protect the environment. We can stop cutting down trees and plant more as it reduces greenhouse gases. Trees absorb carbon dioxide, a greenhouse gas, from the air. We can recycle cans, bottles, plastic bags, and newspapers. When you recycle, you send less trash to the landfill and you help save natural resources, like trees, oil, and elements such as aluminum. You can help the environment if you buy recyclable products instead of non-recyclable ones. Look for the recycle mark - three arrows that make a circle - on the package. Recyclable products are usually made out of things that already have been used. It usually takes less energy to make recycled products than to make new ones. The less energy we use, the better.
