Students can reduce waste and limit their energy usage on campus in many ways. For documents that do need to be printed, students can use double-sided as opposed to single-sided printing. Furthermore, electricity usage can be limited by turning off computers before going to sleep and remembering to turn off the lights before leaving a room. Whenever possible, students should choose reusable products over disposable ones, such as spoons, chopsticks and refillable pens. Moreover, students should make an effort to buy products with packaging that is both recyclable and made from environmentally-friendly materials
State leaders around the world have realized and acknowledged that we are likely to face a global energy shortage over the next few decades, especially in emerging economies like China and India. I believe governments can implement a number of practices to ease impending energy shortages. These include the promotion of energy-efficient practices, restrictions on energy use, and the provision of incentives for alternative energy.
The most basic way in which a government can address the energy shortage is to better educate the public, particularly the younger generation, about the importance of conserving energy. The government can also ensure that the media play an active role in encouraging use of energy-efficient practices. This might include television campaigns to promote the use of bicycles instead of cars, or magazine and newspaper articles on the benefits of better home insulation.
In addition to the above mentioned measures, incentives for the development and use of alternative energies can also play an important role in mitigating the energy shortage.
In the long run we must develop new sources of energy instead of merely conserving the known, limited supplies.
As is shown in the pictures, with the rampancy of commercial fishing, the number of fish has dramatically shrunk. In the first picture, we learn that the year 1900 witnessed a quite encouraging scene of world fishing. There were various kinds of fish and only one fishing-boat. On the contrary, in the second picture, in 1995 there was only one fish swimming freely but many fishing-boats sailing in the sea. It is apparent that a disastrous change has occurred.
The purpose of the pictures is to tell us that due attention has to be paid to the reduction of ocean resources. Owing to the over-exploitation of marine resources, the number of fish has declined at an accelerating rate. If we let this situation continue as it is, we do not know where the fish will be in the future. By that time, our environment will suffer a great destruction.
Hence, it is imperative for us to take drastic measures to reverse this disturbing trend illustrated in the above pictures. For one thing, we should appeal to the authorities to make strict laws to control commercial fishing. For another, we should cultivate the awareness of people that ocean resources are of great significance to us. Only in this way can we protect our natural environment. I believe that we humans can surmount this difficulty and we will have a brilliant future.
As is subtly portrayed in the cartoon, two tourists are taking sightseeing on a small boat while discarding their picnic leftovers casually into a lake. Unfortunately, the lake is already littered and teamed with flow rubbish like plastic containers, fish-bones, banana peel, watermelon rind, bottles, tins, food wrappings, and so on. And below the drawing, there is a topic which says: "after" the travel or "me" in the travel.
From the portrayal, we can conclude that the painter wants to convey such a message: a good many scenic spots are flooded with visitors, who spoil the beauty of nature by creating and leaving behind God-knows-how-much trash. On the one hand, tourism, as a multibillion-dollar business, is booming everywhere. Some people, laboring under the belief that tourism serves as an engine of economic growth, seem to ignore its negative effects on the environment. Nevertheless, these are not concerns that we can shrug off lightly. On the other hand, tourism has exerted great pressure on the environment we are living in: water is polluted, the ecological system is disturbed, and natural resources have been excessively used.
Undoubtedly, tourism could not be banned in any country as it does help to shore up the economy in places which have few sources of income. However, the significant point is that the unchecked growth of the travel business may render the development of an economy unsustainable. It is high time that we enhanced people's awareness to rectify this by taking the environmental protection into consideration.
The drawing subtly reflects that air pollution is becoming increasingly serious in big cities. In the cartoon, there are a large number of cars, buses and trucks driving on the road, and the air quality is extremely bad. Meanwhile, a good many people are constantly coughing in their offices and homes. The magnifier reads: "PM 2.5".
Recent years have seen a rapid increase in the number of urban motor vehicles. Their emissions contribute significantly to air pollution and are a major ingredient in the creation of smog in some large cities. The smog's most threatening aspect is its high concentration of PM 2.5—particulate matter that is small enough to lodge deep into the lungs and enter the bloodstream. No wonder that sometimes people have difficulty breathing or keep coughing.
In my view, it is imperative for us to take measures to reduce vehicle emissions, in terms of fuel quality and vehicle emission reduction technologies. Moreover, planting more trees can benefit air quality and the health of city residents.
It is an undeniable fact that in recent years, environmental pollution, which becomes increasingly serious, has aroused the shared concern of countries around the world. A group of people hold the viewpoint that governments and big companies, rather than individuals, should be mainly responsible for the improvement of the environment. Nevertheless, I am inclined to believe that governments, large companies, as well as individuals should actively shoulder the responsibility of beautifying the environment. In this essay, I will demonstrate my point of view from the following aspects.
Firstly, it is the responsibility of the government, representative of the people, to spare no efforts to ameliorate the environment. To be more specific, government should stage some relevant laws and regulations to severely punish factories which produce a great number of pollutants and those who litter or spit deliberately. Furthermore, large sums of money should be invested in the improvement of the environment, such as the treatment of waste water, trash recycling and so on.
In addition, large companies, on the other hand, should establish the self-consciousness to minimize the possibility of creating pollutants, which may not only be beneficial to the whole country but also to the companies themselves. As an illustration, some transnational corporations are striving to explore some newly-burgeoned industries of high-tech content, high additional value and low energy consumption, taking the place of some high contaminative industries.
Last but not least, it is the top priority of individuals to improve their living space. There is a popular saying which goes like this: “It is everyone’s obligation to protect the environment.” Most importantly, we should strengthen the consciousness of environmental protection, not only strictly being self-disciplined but also supervising people around. So to speak, it is unreasonable to claim that individuals have nothing to do with environmental protection. From what has been discussed above, we can safely draw the conclusion that government, big companies and individuals should make their due contribution to salvage the deteriorating environment.
