Many sources says that people are the most important human being in the land, and it seems yesterday that people was not a problem, but how come now it is? That’s why now overpopulation exists. Overpopulation is now consider as one of the biggest problem of our society because according to some surveys that has been conducted it also one of the reason that lead our society to poverty. But, let’s define first the overpopulation. According to the Wikipedia overpopulation is a generally undesirable condition where an organism's numbers exceed the carrying capacity of its habitat. The term often refers to the relationship between the human population and its environment, the Earth, or smaller geographical areas such as countries. Now the Philippines are one of the overpopulated countries in the world. According to the Central Intelligence Agency(CIA) who conducted the survey last April 2012, Philippines was in the rank 12 and that only shows that we are having a problem about the growth population of our country. According to Heinz Nicolas who is an internet blogger many of the people here in the Philippines, especially teenagers, are engaged in prostitution and premarital sex, which are two of the common causes of overpopulation. One also of the causes that we can see is the lack of knowledge and education about family planning, and mostly the big percentage that contributes to the overpopulation of the country was came from the poor people. The other factor also that contributes to the causes of the growth of overpopulation is because those people from other provinces kept coming from different part of the Philippines to settle in the city. Some also came from the immigrants who chose to live here in the Philippines and that also added the percentage of the population here in our country.
