You are very right with one of the factors being "Poverty" and then lack of sex education. I would also say that people who are living in abject poverty are ignorant of the number of children they ought to have, but they believe the more children they have, the bigger the chances of escaping poverty. They will only end up distributing these children into different skills and would sell many of them out in exchange of money because they can´t take care of them. With this, the children aren´t taught sex education and that is how the problem of overpopulation begins. I believe if families are educated and enlightened about family planning and contraception, the number of children being given birth to will be reduced but as it is, I don´t think there are those who would want to understand all of these are causing problem to the earth.
