Worldwide population growth is the result of several interrelated factors. Food, the generalization of hygiene, health, the dissemination of medicines and in general the development of technology that allows the world population to be interconnected and communicate in a matter of seconds regardless of the distances, which encompass the term "globalization", have been decisive for the strong growth of the world population, which has passed from almost 1000 million in the year 1800 to more than 6000 million in 2000 and about 7000 million at the end of 2011.
Thus, we can affirm that globalization has been decisive in fostering the growth of the world population, since it created the necessary conditions that led to an increase in the quality of life of the people.
The main effect of overpopulation is the unequal and excessive consumption of resources. The planet has a limited capacity to generate raw material and each year the deficit of natural resources - consumption of these resources at a faster rate than the planet is capable of generating them - arrives earlier. As a consequence, in developing countries, overpopulation exerts an excessive pressure for control of resources. Territorial conflicts over water supply are in many cases leading to geopolitical tensions that could lead to wars.
In addition, the excessive consumption of natural resources as well as the growth of energy production from coal, oil and natural gas (fossil fuels) is having a negative impact on the raises. On the one hand, consequences such as deforestation and desertification, disappearance of animal and plant species, changes in the water cycle ... to which is added the most direct consequence of the emission of large amounts of greenhouse gases, global warming.
