Science Daily.com reports that soon this year we will reach 7 billion people in the entire world population. In 1999 there was 6 billion, this means that in 12 years we gained an extra 1 billion people.The United Nations, expects around 10.1 billion people by 2100. At least these projected people will be occupying most of today's areas that are not as populated and Africa.
Still this insane amount of people that have not even been born yet are already causing problems for those of us who are already here. We now have to think about food supply, water supply, housing, and energy. This also means that with less space, everyone will be in closer distances of each other. This means that disease can go through populations a lot quicker. Health will be another top priority to worry about. David Bloom from the Harvard School of Public Health said "Those challenges are not insurmountable, but we cannot deal with them by sticking our heads in the sand. We have to tackle some tough issues ranging from the unmet need for contraception among hundreds of millions of women and the huge knowledge-action gaps we see in the area of child survival, to the reform of retirement policy and the development of global immigration policy. It's just plain irresponsible to sit by idly while humankind experiences full force the perils of demographic change."
