The global rate of human population growth peaked around 1963. However, the number of people living on Earth and sharing scarce resources like water and food has grown by more than two-thirds since then. Population growth causes multiple environmental problems, such as the clearing of rainforests, the loss of thousands of plant and wildlife species, an increase in greenhouse gas emissions. In our class, we addressed few philosophical positions and arguments about population and environment issues from each author. They tried to find out root causes of population growth and solve the problems behind. In this paper, I would like to discuss two main arguments of environmental issues that caused by population growth. The first argument is from E. Ravenstein’s theory about migration affect environment and economy. The consequences of climate change on migrant on present humanity with an unprecedented challenge. Ernst Ravenstein established a theory of human migration in the 1880s that still forms the basis for modern migration theory. It considered the implications of distance and different types of migrant, with women more likely than men to migrate within the country of their birth but less likely than men to leave the country of their birth. The theories are as follows: (From lecturer)
• Every migration flow generates a return or counter-migration.
• The majority of migrants move a short distance.
• Migrants who move longer distances tend to choose big-city destinations
