The Problems that Our World Faces Today

The earth is considered as one of the most beautiful planets in the universe. It is the only planet in our galaxy that has enough water to support life. Unfortunately our planet is suffering due to many problems which should be solved before it is too late. The major problems that are facing our world today are population, pollution and animal extinction. One of the problems facing our world is population. It began about ten thousand years ago when the humans settled and began farming. The farming provides more food for the people thus making the population grow. Now we are about 6 billion in population and in a few years we will be around 10 to 11 billion. Therefore, our population will…show more content…

Pollution is another major factor that is threatening our world today. One example of pollution is nitrogen. Humans are adding about 130 to 150 million tons over the 90 to 150 tons that are produced by the nitrogen cycle. This excess in nitrogen causes coastal waters and estuaries to grow toxic algae, killing the fish and trapping the solar heat in the air. Another example of pollution is methane. Methane is produced by gases released by cows, termite mounds or by the bottom of rice paddy. If found in the air methane is very poisonous. By raising more cattle, cutting more tropical forests, thus increasing the amount of termites, and by growing more rice, the methane concentration in the air is almost twice as higher as it was 160,000 years ago. Smoke is another pollution factor. Smoke that is produced by cars contains carbon dioxide (CO2). This carbon dioxide in the air causes global warming, which results in the green house effect and climate changes. Satellite studies show that perhaps we will increase the temperature by 3.6 degrees by the year 2001. The warmer the weather the more water it can hold, the higher the precipitation will be. The higher the precipitation the more clouds, the more rain, and the more snow there will be. This will result in more storms and floods. Studies by Thomas Karl of the National Oceanic and Atmospheric Administration showed that the total winter precipitation in the US has increased to about 10% since
