The world is not only hungry but also thirsty. However, some people are still reluctant to turn a finger to save water. Some people dont turn a tap after use, while others even pollute clean water and make the situation worse. The severe drought in the southwest China once again pushes the issue of water-saving under hot discussion.
However, as things stand today, the reasonable utilization of water resource is more significant than before. Firstly water consumption is soaring. The quick development of commerce and industry will consume more water for their reproduction. Whats more, the great increasing of the world population also further aggravates the situation. Secoodly, due to the more and more serious water pollution, the supply of clean water fails to meet the demand.
As a college student, not only will I save water by myself, but also I will attend different kinds of activities on water-saving. On the one haod, I will make the best of water instead of throwing clean water away at instant. On the other haod, I will call on my friends to save water and protect water. Anyway, many a little makes a mickle.
Due to its highquality and original tastes, green food appeals to more consumers. From supermmarkets to chain stores, green food is found everywhere.
Why is green food so popular even though its price is usually higher than other food? On the one hand, recently a series of issues on food safety makes customers disturbed and anxious. In order to have the reliable food, more housewives opt to select green food for their family. Green food has been labeled as a kind of healthy, delicious and fashionable food. This is perhaps the most important reason for the popularity of green food. On the other haod, with the advance in living standard, people will pay more attention to the quality of food and their raised income is enough to cover the expenditure of food with a comparatively high price.
With the development of the society, green food is certainly to hold a larger portion in the market. In the near future, people will be accustomed to enjoy the fresh vegetable, fruits and cereals without pesticide residues, artificial feed and contarnination.
Its no doubt that university campuses will produce a large amount of rubbish every day, however, there are fewer college students paying attention to its classification.
Factually waste separation is vital to create an environment-friendly campus. Firstly, waste separation does great contribution to the environmental protection. Since some of waste is recyclable, while other is unrecyclable, if all the students could voluntarily differentiate recyclable rubbish from unrecyclable rubbish, the risk of the environmental pollution will be greatly reduced. Secondly, waste separation could save a lot of energy and tirne on its processing.
With the rapid increase in the amount of rubbish at the campus, rubbish classmification does not permit of any delay. On the one hand, as the well-educated people, college students should act as hosts of the universities and separate waste from this moment in their daily life. On the other hand, university authorities should strengthen students awareness of environmental protection and guide students to separate waste in a reasonable way.
Recently, it is reported that oil price in the intemational market has been skyrocketing drastically. In China, many traditional mineral cities in northeastem China has run into predicament, with their economy collapsed and workers unemployed, only because coal has been mined out.
Unlike sunlight, water and wind, fossil energy resources , including coal, oil and gas, are not practically reproductive during human history. Once consumed, theyre gone forever. If they were to be exhausted before we could find sufficient resources to replace them, we would have to live in entire blackout again, which is of course not what we would like to see.
Therefore, we must economize on energy resources. New techniques should be developed and applied to reduce energy consumption in industry and daily life. Altemative energy should be employed wherever possible. Any practice that wastes energy should be eradicated .
