1 . Humankind has tried to improve its standard of living since the very beginning of civilization (文明). Back then, and today, providing food was the basic task for a person.     1     People feel the need for not only some primary things, such as bread and shelters, but also for various facilities and luxuries. Providing humanity (人类) with these things is connected to the use of natural resources, which requires energy. In turn, the common sources of energy we use today cause pollution, so economic growth is almost inevitably connected with environmental damage.

    2     The first of these is the fact that in order to produce more goods and products, at a faster rate, the construction of large industrial plants is required. These plants produce a lot of waste, which may cause negative long-term health effects to nearby populations of animals, or people.

The traditional energy sources, which are commonly used nowadays, are considered to be the greatest polluters to the environment. There also exist so-called eco-friendly sources of energy.     3     Of course, during this time people have to make some sacrifices to support these undertakings (企业) .

In order to produce practical energy, a transformation of the natural site is often inevitable (不可避免的).     4     Application of wind energy would block airflow’s natural speed. Consequently, the pressure balance that is brought about by this current will be affected, and it is important to remember that the environment and weather conditions are directly affected by atmospheric pressure.     5     This is the embarrassment mankind has to deal with. A good balance between economic development and sustainability is forever what humankind has to keep in mind
