PERSPECTIVES ON POPULATION GROWTH Based on the current trend‚ there will be a total to about 9.2 billion people on the earth by mid-century‚ fuelled by the birth of 220000 children a day and falling mortality rates (Population Institute‚ 2014). This estimate raises questions about the future of humanity and the planet we inhabit. The debate about an optimal size for human population is one that has waged over the years. The question is fundamentally about sustainability; whether the resources that

Aftermath: Population Zero Imagine if one minute from now‚ every single person on Earth disappeared. All 6.6 billion of us. What would happen to the world without humans? How long would it be before our nuclear power plants erupted‚ skyscrapers crumbled and satellites dropped from the sky? What would become of the household pets and farm animals?

Population: Is Anything Being Done? In Chapter III of The Origin of Species‚ Darwin writes: "Even slow-breeding man has doubled in twenty-five years‚ and at this rate‚ in a few thousand years‚ there would literally not be standing room for his progeny." (Darwin 29) Three hundred years ago‚ the population was only at about 500 million‚ and during this time the population was at a slow increase. Another factor during this period of time was the birth and death rates were at much higher levels

Population Viability Analysis Introduction Over the last few lectures we’ve talked about the stochastic threats to persistence in small populations. We identified five classes of threats and some of their qualitative properties: 1. Genetic stochasticity — Not a problem in populations with Ne greater than a few hundred. Therefore‚ not likely to be a problem in populations large enough to buffer environmental stochasticity 2. Demographic stochasticity — Unlikely to be a problem in populations with

Abstract Water is a finite resource which means that the total amount of water in the planet is only limited. Its supply remains the same and yet human population recently grows resulting to a decrease of available amount of freshwater per person. The relatively small amount of available freshwater elaborates on how critical it is for everyone to help preserve and maintain clean‚ healthy lakes and streams‚ our sources of water. Water is mostly now being wasted because it is under-priced. We do not
