Population Growth Population Growth Do you live in a city full of people that seem to be increasing in number every day' Or maybe you live in a rural area that more and more people are moving to. If you do you have personally experienced the effects of population growth. Population growth effects the availability of resources, climate, and the disease rate around the world and in your very own community. Population growth and the environment are closely related, but the links between them are complex and varied. As the population grows and demands increase, the search for water, food, and energy resources becomes more difficult. As a result of population growth, water use has grown six-fold. Worldwide, 54% of annually available fresh water is being used, 2/3 of it for agricultural purposes. In the year 2000, 508 million people lived in 31 water-stressed or water-scarce countries. Also, in many countries , population growth has raced ahead of food production in recent years. Between 1985 and 1995, food production lagged behind population growth in 64 of 105 developing countries studied with Africa faring the worst. In the twentieth century, human population quadrupled ,from 1.6 billion to 6.1 billion. And carbon dioxide emissions, which trap heat in the atmosphere, grew twelve fold, from 534 million metric tons in 1900 to 6.59 billion metric tons in 1997.
