Definition + causes and effects of the global warming

A global warming is one of the most dangerous problems that face the humanity and the whole world. Global warning is the name that is given to all the environmental problems that cause a lot of damage on the earth and the ecosphere around it. It contains the air pollution, sand pollution, water pollution, ice melting, diversity, loss of food and water, loss of energy and even the loss of land that we live on it.

There are a lot of causes that lead to the global warming. The most common one is the greenhouse gases. Greenhouse gases are water vapor, carbon dioxide, methane and ozone. The largest contributing source of these gases is the fossil fuels when they are burnt. They have a bad effect on the earth when they absorb the sunlight radiated back to the earth leading to reflecting back of the heat energy by atmosphere. This energy will then lead to other problems that considered as parts of the global warming. One of these problems and effects is increasing the temperature on the earth which then leads to other major effect, rising of sea levels. This increase in the temperature melts the land ice. As a result, the sea and ocean levels will be increased leading to destroy the beaches of many islands. Actually, there are by now some islands that no longer exist because of the global warming.
Many people think that caring and thinking about global warnings in these times is not necessary and it wastes the time. They think that it is too early to think about it. They don’t even know that they are the main reason for global warnings. One day, they will find themselves in a close circle of the environmental problems that they can’t escape from it. On the other hand, there are some people that have feelings and care about the earth and the pollution on it. If we all help each other, we will be able to save the humanity and the whole world form the global warnings.
