A sobrepopulação tem vindo a ser reconhecida como a principal causa da maioria dos problemas ambientais, na medida em que o excesso de consumo está a ameaçar a sustentabilidade do planeta.
Em 1950 o número de população mundial era cerca de 2,5 mil milhões de habitantes, passando a 6 mil milhões no ano 2000. Apesar deste enorme aumento, a taxa de crescimento da população tem vindo a diminuir nos últimos 20 anos. Esta diminuição ainda não é visível com uma certa clareza pois grande parte das pessoas nascidas nos últimos 70 a 50 anos ainda se encontram vivas. De acordo com a Organização das Nações Unidas, prevê-se que a população mundial continuará a aumentar, alcançando os 11 mil milhões de habitantes até ao final do século. Estes dados permitem perceber a dificuldade de resolver os problemas associados à sobrepopulação, nomeadamente em relação à exaustão e consequente escassez de recursos naturais. Nos países em desenvolvimento, a taxa de mortalidade tem vindo a reduzir bastante após o fim da Segunda Guerra Mundial, devido à implementação e promoção de campanhas de saúde pública e de vacinação, tendo como resultado uma redução significativa de doenças. |

“…..world population is projected to reach 7 billion. How we respond now will determine whether we have a healthy, sustainable and prosperous future or one that is marked by inequalities, environmental decline and economic setbacks…
The milestone of 7 billion is marked by achievements, setbacks and paradoxes. While women are on average having fewer children than they were in the 1960s, our numbers continue to rise. Globally, people are younger—and older— than ever before. In some of the poorest countries, high fertility rates hamper development and perpetuate poverty, while in some of the richest countries, low fertility rates and too few people entering the job market are raising concerns about prospects for sustained economic growth and about the viability of social security systems.
While labour shortages threaten to stymie the economies of some industrialized countries, unemployed would-be migrants in developing countries are finding more and more national borders closed to them and the expertise they may have to offer. And while progress is being made in reducing extreme poverty, gaps between rich and poor are widening almost everywhere.
The State of World Population 2011 explores some of these paradoxes from the perspective of individuals and describes the obstacles they confront—and overcome— in trying to build better lives for themselves, their families, communities and nations.
Through personal stories, this report sheds light on the real-life challenges we face in our world of 7 billion…..”
