As is graphically pictured in the miniature above, there is a large amount of rubbish floating on the surface of the lake, and taking a closer look at the miniature, we could find easily that on the boat sits two sightseers who are throwing rubbish causally with no regard for the feeling of our fragile nature. It is impossibly apparent that the miniaturist is aimed at criticizing those who don’t safeguard but even ruin our shared and only ecosystem and calling for all of us to preserve our lovely homeland. Undeniably, our environment has ever been deteriorating amid the truth that we exploit the natural resources excessively and, meanwhile, turn a blind eye to the preserving of ecosystem. If the ecosystem were ruined,without exaggeration, we, humanity, would pay dearly for our own behaviors now. In effect, it is hardly surprising that we repeatedly saw these reports or headlines to the effect that there were far too many visitors from some cities or nations throwing rubbish in some well-known traveling points and even witnessed frequently those uncivilized acts in that moral education is being paid little attention and civilians’ protection awareness has a large room to improve.It is universally acknowledged that our planet was, is and remains our greatest mother breeding our ancestor, ourselves, and offspring.In consequence, it is wrong, no matter of what respects, that we simply take all the life necessities provided by our nature, such as, food, air, shelter, etc. for granted. And we shouldn’t be the man with unabashed greed, that is, we are bound to learn to repay our planet, at least stop destroying it. From my perspective, we all people are duty-bound to step up initiatives to safeguard our only ecosystem, which has been becoming fragile. Initially, moral education in our nation, especially the education for youngsters, ought to be strengthened and deepened. Moreover, the environmental awareness among the general public must be raised. Above all, department concerned are under the imperative to form relevant laws and regulations to penalize those with indecent behaviors. Only in a community where environment protection was drawn great attention can we enjoy a more harmonious, fitting, and healthier settlement to survive. 本文来源：https://www.wddqw.com/doc/3353c613abea998fcc22bcd126fff705cc175c91.html
