Which one of the following is an environment related disorder with the correct main cause ?
Answers
In a purely mathematical answer, when the rate of births exceeds the rate of deaths the whole population will generally grow by that higher rate difference. It is also influenced by the fact that there is a much larger population producing offspring at the higher rate difference, plus the medical fact that people are living longer than ever before.
Mother Nature will continue to do her best to balance out the number that can exist at one time on this planet through weather, geological and physical events affecting the planet, occupants’ poor personal decisions (i.e. drinking and driving), bacterial and viral mutations requiring new vaccines, a disruption in the hunter/prey ratio, and the human propensity alone for doing evil to other members of its race.
Most biological entities on this planet have always existed on the very edge of too few and too many of them being here, including humans which are considered by some to be the real vermin of the earth.
