求一篇英语口语对话what should we do to take care of our Mother Earth?

As we know, the pollution problem has reached a critical level. Not only was the ecological balance being damageed seriously in the past decades, our health and living qualities have also been badly affected. For the sake of the future of our decendents, we should really start to protect our environment. In my opinion, the current environment problems are maily caused by the heavy industries and manufacturing. To get economic interests, some countries destroyed their local environmet to build factories. On the other hand, some unqualified factories prodice lots of pollution untreated. Besides, the tremendous usage of petroleum for cars, and other transpotation vehicles also produced greenhouse gases. All these factors contribute to the dilemma of our current environment. As such, I feel that all the countries shuold transform their economies to the technology-intensive, environment-friendly economies so as to reduce the mass pollution from the old industries. The developed countries also should help developing countries such as offering loans, transferring clean technologies. As members of the world community, the individuals should also take low-carbon lifestyle to protect our environment. For example, peoplle could take public transpotation instead of using their own cars, switching off the lights when leaving their rooms. Although one can do little to change the situation, the collective efforts of all the individuals would make a difference.
