My summary


My blogger is about the dangerous problem which faces all worlds nowadays and in future. This problem is global warming which mean increasing the temperature of Earth. This problem has many causes and effects and also it has some possible solutions. The main causes of global warming are that the emission of carbon dioxide and other greenhouses gases on atmosphere. As we can see from the diagram which shows different greenhouse gases which effect in the temperature of earth. It shows that CO2 is the most important followed in descending order by methane, CFCs, ozone and nitrous oxide. However there are many activities that cause emission of CO2 such as Carbon dioxide from cars, airplanes, ships, factories and when we burn fossil fuel. A further cause is that widespread deforestation has also had a negative impact, releasing more CO2 into the atmosphere. Trees and other plant play a role in balancing CO2 and Oxygen level. There are many effects of global warming. The major effect is increasing sea level. Rise of sea level has many effects on our environment. For example, harricune of Katriena which killed million of people on it is one of the effects of increasing sea level. There are some possible solutions for that problem like use clean wind and solar energy. We also must make our cars go on a gallon of gas. Yet another solution is that planting trees and forest restoration which can help to absorb some of excess in the atmosphere, as well as providing habitat for a wide range of very special wildlife, and giving it a better chance of adapting to climate change.
