It's really quite ironic whenever tackling with the issues of protecting the environment of our earth and cherishing the gradually decreasing natural resources to lengthen its fragile life during the last half century; we find we're sabotaging them at random and without care.

　　We're now and then reminded ourselves or simply educate ours decedents of turning off all the appliances if they're not used in families, classrooms, offices, plants, and any other common occasions to reduce any forms of unnecessary waste, for example. The result seems less satisfactory most of the time.

　　Action speaks louder than words. The time to do something helpful to better our earth is absolutely far more than just a need. Only when the majority of our global citizens have reached such a consensus and can constantly put it into practice may our living planet grow longer and prettier.
