In today's world there are many problems facing the welfare of humankind, which could affect our existence in the future. If these problems are not recognized, and the appropriate actions are not taken to slow down or put an end to them, then the consequences could be overwhelming. Three problems that are facing the well being of all humans are consumption of natural resources, over population and problem with pollution. The consumption of natural resources and over population can be traced to the growth of the world population. As more people live on the Earth, more resources are consumed, therefore increasing pollution. If each person does a small part to cut down on pollution or conserve natural resources, then the result would be tremendous. Each person must realize that by performing a small task, they can help the greater society.
As previously mentioned, as the number of people on Earth increases, more and more resources are needed in order for these people to survive. The demand for resources that are necessary for survival and convenience are consumed at an incredible rate. The first example that comes to my mind is the overwhelming dependence on oil and gasoline. There is an amazing reliance on gasoline and oil as fuel for cars, airplanes, and many other machines. This dependence becomes greater as more and more cars are produced and the demand for gasoline increases. A recent indication that the supply of gasoline may be suffering is the increase in gas prices. The consumers must continue to buy the gasoline because it has become an essential part of their everyday life. Alternatives to gasoline-powered cars have been invented, but have not been able to catch on with consumers. For example, electric powered cars have been unveiled, however they do not get the same mileage as gasoline powered cars and are more expensive. Until people are forced to drive cars that aren't powered by gasoline, there will still be a huge reliance on gasoline and oil powered cars.
