What is pessimist view on population growth?
The pessimistic viewpoint on population growth is that they think that a population which has a high growth rate will put a strain on resources. They believe that there will not be enough resources to be able to supply the large population. ________ Population pessimism remains associated with Thomas Malthus, who warned in 1798 that humans would tend to multiply their numbers while resources available for their upkeep were limited, resulting in susbsistence crisis. This failed to happen in the 19th and 20th centuries as both global population and living standards rose at an increasing rate, though some countries suffered periodic famine as had happened in past centuries. The rate of world population increase is now falling, but it is likely to take a century for growth to end. Pessimists today fear that this slowdown will be too little and too late to prevent catastrophic ecological and resource crisis, while optimists hope that reduced fertility and technological advance will allow a "soft landing" and avert disaster.
Why is population growth a concern?
As population increases, the resources of the surrounding environment will be consumed. The greater the population the greater rate of consumption. The Environment will be cleared to make houses... Natural resources will be extracted, be it for energy production (coal), Exporting (lumber, anything with any value). The rain forest in Brazil is being cleared for Cattle and livestock to graze upon. More people = more consumption of the environment.
Why is county fermanagh so sparsely populated?
Fermanagh had a population of over 156,000 in 1841. But after the Famine and continued emigration from the county, the population declined to an all time low of 49,000 in 1966. It has since increased to over 55,000 but still remains a very rural county with few job opportunities.
How much has the population decreased in the world?
The population has not decreased in the world, population has increased. Although it all depends on the time-frame you are talking about. And whether you are talking about humans or all animals, and are you talking about one single country or the entire planet. The fluctuation of human population on a yearly basis may look like the population is decreasing, because of all the catastrophes lately, but when you are looking the big picture, a much longer time-frame, you will notice the amount of humans has rapidly grown over few decades. We are very soon running out of space to live on and feed everyone. This statement is based on basic calculations on human population doubling time. For example, given Canada's net population growth of 0.9% in the year 2006, dividing 70 by 0.9 gives an approximate doubling time of 78 years. Thus if the growth rate remains constant, Canada's population would double from its 2006 figure of 33 million to 66 million by 2084. Let me put this in another way. Let's say the world is a bottle (a limited living space). Also, let's pretend we fill the bottle with people 1/4 full today. Also, if the doubling time to the population growth is same rate as in Canada 2006(0,9% growth rate a year), the bottle would be half full by the year 2089. If the growth rate continues to be 0,9% a year, by the year 2167, which is yet another 78 years from 2089, the bottle -the world- would be entirely consumed. Now you may wonder howcome the bottle jumped from half full to entirely full in just a one doubling time. This is because all the population doubles. Not just the second quarter in the bottle. Yes ofcource there are old people, who do not make more children. But that is already taken into calculation in the 0,9% yearly growth rate. The population doubles every 78 years. Unless some kind of natural disaster slows the population growth down.
