With the increasing influence of the Earth surrounding, the claim that the needs of humans are more important than those of animals and other creatures can hardly exist- there is only one Earth for us human to live on, and at all. More and more attention is paid to resource-saving programs, greens protection, or reducing of carbon dioxide in order to against the Globle Warming. As moral students, we should start to protect our Earth from pollution and distruction; Planting more trees, using less oil-using transportations, or recycling paper products. These are all the little things we can do and let others follow to help protecting our Earth- and they are efficacious, too. In short, I think it's clear that if everyone of us can begin with Earth protection, our living areas will have less pollutions and stress; the sky will be clearer, the water will be safer, and the world will be better.
