What can we do to prevent the decrease in preserved natural areas

I think this is a complicated question, which is hard to answer. Taking China as an example, it’s a trend nowadays to migrate to cities from rural areas; Cities have everything that a person needs: more job opportunities, good schools, the best hospitals, etc. Most people believe that they are more likely to find employment and enjoy a better quality of life, but the movement of population to urban areas can cause many problems. In order to accommodate more people, it’s unavoidable to expand cities into the surrounding natural areas, because the urban space is limited. However, I think every problem has a solution, especially as economy and technology have been improved a lot in recent years. Within the government, authorities have more options to improve the situation. They are able to increase infrastructure construction in rural areas, re-allocate services and opportunities to different rural areas, design space-saving houses, create a more balanced economy to help preserve the environment. Apart from the government’s efforts, normal people should also try to do everything with becoming green. The viewpoints above are the most effective methods I have learned, even though they can only slow down the problem caused by the growing population. I hope a new planet can be found for immigration or that scientists invent artificial space off-earth for living.
