Ironically,we, human beings, are now facing a series of environment-related issues ranging from various contamination to global warming to the depletion of natural resources although our economy keeps on prospering. As to how to address environmental issues, an opinion seems to enjoy great popularity that personal efforts are too trivial to optimize our living surroundings, however, the issue is surely relevant to each individual citizen.
No matter how small personal involvement in environmental conservation might be, it is the unshakable obligation of every individual to safeguard the environment. The amelioration of the environment should and could be realized by every kind of little effort. A number of examples might justify my stand, instead of depending on private cars excessively, the public should be inspired to take public transit, walk on foot or ride bicycles, which could mitigate the pollution induced by public transport. Imaginably, we could enjoy a cleaner and quieter environment if there are few vehicles on the roads. Meanwhile, provided that we have to utilize personal cars, it is highly recommend that we should purchase and drive compact cars or full-cell- driven cars.
