For individuals and a country, human survival is the first priority to be resolved. Although environmental protection has been increasingly mentioned and concerned, it is always second to solving the problem of "eating". This is also the reason why developing countries repeatedly follow the old path of pollution first and then governance in developed countries. It is not that they do not see lessons, but that the arduous task of seeking development has made countries have to take shortcuts, prefer coal, which is cheap and reliable, and increase poverty. The living standard of the population can also promote employment as a developmental energy source. What does this text mean? ['Environmental protection and economic development are equally important.', 'In order to survive and develop, developing countries have to deal with pollution before treatment.', 'Solving food and clothing is more important than protecting the environment.', 'Developing countries neglect environmental protection for development.']
