▆ Answers for reference:

Human beings live in the realm of nature. They are not only dwellers in nature, but also transformers of it. With the development of society and its economy, people tend to become less dependent on nature directly, but indirectly their dependence grows.

Human beings are connected with nature by “blood” ties. No one can live outside nature. However, the previous dynamic balance between man and nature has shown signs of breaking down. Problems such as the population explosion, ecological imbalance and the shortage of natural resources have become major factors keeping human society from being further developed.

Professor Spirkin holds that the only choice for human beings is the wise organization of production and care for Mother Nature.

Theme-Related Writing

▆ Write an essay of no less than 150 words on the topic “My Understanding of Environmental Protection”. Your writing should cover the following points:

1) the relationship between man and the environment

2) the urgency of environmental protection

3) ways to protect the environment

▆Sample essay

My Understanding of Environmental Protection

Man and the environment are closely related. Man relies on the environment for water, food and shelter. A harmonious relationship between man and the environment is essential for human survival on the earth.

However, man and the environment have never been on such bad terms as they are now. As society develops, m an’s transformation of nature has severely polluted his living environment. Deforestation leads to changes in rainfall patterns, causing devastating floods, droughts and sandstorms. The discharge of chemical pollutants endangers our health and the lives of other beings. And mass production has resulted in the shortage of irreplaceable natural resources such as coal and oil. If we take no immediate and effective steps to protect our environment, human beings may be the next species to become extinct.

We should do our best to protect our environment by planting more trees, taking care of wildlife, reducing industrial wastes, using renewable energy, and imposing heavy fines on environmentally-unfriendly activities, so as to preserve the environment for future generations.
