侵华日军南京大屠杀遇难同胞纪念馆，二期建筑色调都是灰色、黑色，突出的是战争、悲伤、哀悼，而三期的胜利广场是绿色的、胜利之墙是红色的，色彩丰富了许多，这些元素突出了“圆满”、“胜利”、“浴火重生”的主题。围绕着胜利广场一圈的是铁红色的“胜利之墙”，上面镌刻着为抗战胜利做出伟大贡献的英烈之名。而在“胜利之墙”最前面“7”字形的标志物上，是火炬台，上面设置火炬。这种设计，赋予纪念一种昂扬的基调。 致富小机器 另外，广东电信还推出八项服务承诺，其中包括宽带、固定电话可实行预付费、用户欠费将提供申告服务等。据悉，广东电信的电话用户已经超过3100万，宽带用户接近300万。
People have learned how to turn wild natural areas to farmland, how to exploit minerals to adapt their needs, how to build roads and houses to expand their territories. People continuously improve their knowledge and develop technologies to improve their lives. It is undeniable that these activities of human beings make their lives better than ever before. Nevertheless, those activities also cause side-effects to the Earth because of pollution, deforestation, and exaggerated natural resource exploitation.
Nowadays, pollution becomes one of the most concerned problems. Because of the increasingly expanded factories, the industrialized areas, the burning of population etc, too much pollutant spills out everyday. Consequently, all of these things cause bad effect to the Earth. The purity of atmosphere is reduced seriously, the Earth is continuously warmed up, and ozone layer is holed.
Additionally, forest is asking for help in desperation. For last few decades, the forest areas have been reduced to 50 percent because of human deforestation. Green forestland of the Earth can be compared to the lungs of human. How healthy you are if your lungs are trespassed. I am sure that you will get more difficult with aspiration; as a result, your health will be affect badly. From this example, we can infer that how serious problem our Earth has to face with. I wonder how long it can endure.
Researchers show that the natural means is limited, but today, they are exploited so increasingly to adapt infinite human needs that someday, all mineral can be ended up. Because of serious pollution, alarming deforestation and progressive mineral exploitation, the ecosystem becomes unbalance. Consequently a lot natural calamities happen each year such as flood, hurricanes. A lot wild living creatures are exposed to narrow place of shelter and lacking foods. For these reasons, the Earth will become unhealthy.
In conclusion, the human beings harm the Earth. Human beings as well as their dear planet, the Earth, have been badly suffered by what caused by humans themselves. I hope that humans are soon aware of those problems so that they can have suitable policies in order to not only improve their lives but also keep and maintain the Earth fresh and green.
