The effects of washing machine without water (Final)

Last year a student who had graduated from the University of New South Wales innovated a washing machine which can use sunlight instead of water and washing powder to wash clothes. According to the student's design, the light in the house can operate powerful oxidants which can decompose filth into carbon dioxide and water. I think that it will be popular because it can save water, reduce the usage of washing powder, and there is the smell of sunlight on the clothes.

The most important effect of the washing machine is to save water. Saving water is a very important issue. It is said that in 2025 if we only depend on the source of nature, the world population of 7000 million people will face the pressure of water shortage, even in the area where there is affluent water, such as America and China. If there are adequate solutions to the problem of water shortage, we do not have to worry about taking a bath and cultivate crops by consuming water.

The second effect of the washing machine is to reduce the usage of washing powder. We should use little washing powder owing to it causes not only the pollution of environment but also a variety of diseases. The lakes in my country are in eutrophication because of a great deal of phosphorus.

In addition, the composition of surfactant in washing powder will irritate our skin and harm our health.Another effect of the washing machine is that there is the smell of sunlight on the clothes. Having it, my clothes will still smell good even the weather is bad.

In conclusion, the washing machine helps a lot on the part of environmental protection no matter how to save water or reduce the pollution of environment. I believe that it will become essential in our lives. If you have a heart loving the earth, it is time to act-buying one.
