How does population growth affect the limitation of natural resources?
Q. I have that question and a couple more: How does population growth correspond with disease and poverty? What has the United Nations done to promote a reduction in population in the past five years?
Asked by help? - Mon May 18 21:07:55 2009 - - 1 Answers - 0 Comments

A. Well population growth affects the limitation of natural resources because people need to use those resources and as more people are around more people are using those resources so eventually they will run out, like oil. Population growth corresponds with disease and poverty because when they're more people disease spreads from person to person faster because you are closer to people, it corresponds with poverty because a percentage of the population will always be living in poverty and when they're more people, more people will be living in poverty, if you mean growth of poverty it is because it is easier to monopolize the country and make lots of money that other people don't have. I'm not sure about the answer to your last question… [cont.]

A. Selfishness and greed is an unfortunate trait of human imperfection, but it can be recognized, controlled and eventually done away with individually. However,the worldwide economical system has been set up on greed, to live off of others. It is based on greed and love of money, self interest. The hardworking "ordinary" person and those classified as minorities, for what ever reason, are pretty much the ones who get taken advantage of by a system that has been set up to cater to the "upper class big wheels" so to speak, while providing only crumbs for the ones who really deserve better for their efforts.

How do I do this population growth problem, using the logistic equation, with differential equations?
Q. Consider a rabbit population P(t) satistying the logistic equation. If the intial population is 120 rabbits and there are 8 births per month and 6 deaths per month occurring at t=0, how many months does it take for P(t) to reach 95% of the limiting population M?
Asked by Larry L - Wed Nov 5 20:22:34 2008 - - 1 Answers - 0 Comments

A. The differential form of the logistic equation is: dP/dt = r*P - (r/M)*P^2 where P is the population as a function of time r is the growth rate M is the carrying capacity (the limiting population) In the above equation, the first term on the right hand side represents unfetttered exponential growth of a population (i.e., the birth rate), while the second term represents the effects of competition and death. We can equate the first term with the birth rate to find the value of r for this problem: 8 rabbits/month = r*P(0) = r*120 rabbits r = 1/(15 month) Now equate the second term with the death rate to find M: 6 rabbits/month = 1/((15 month)*M) * (120 rabbits)^2 M = 160 rabbits The solution to the logistic differential equation is: [cont.]

A. Two words: Industrial revolution. Technological advances which occurred as a result of the process of industrialisation meant that death rates fell and at the same time, birth rates remained high resulting in an increasing population. Why did death rates fall as a result of industrialisation? * Improved nutrition - The agricultural revolution accompanied the industrial revolution meaning that there was a better supply of food * Awareness of the causes of diseases such as cholera - which meant plans could be implemented to prevent them * More people were earning more money which improved their quality of life in terms of the food etc they could afford to buy

A. What I did when I was writing my SF novel was to think of the USA. If you take what happened from 1492 to the present and find out the current population of the US it could give you a rough template to work on. But remember that their may be other factors in your futuristic tale that might impact on your eventual population. And I suppose you have to ask yourself the question of whether or not you should go into such detail at the outset. I did not mention a number but did state that many billions had made their home there. So there are ways of working around using an exact figure unless of course it has a significant bearing on the story. Hope this helps a bit. Good luck.

Asked by clueless - Sun Jun 14 22:07:09 2009 - - 2 Answers - 0 Comments

A. It all depends on what you mean by 'population'. If you mean numbers, then we think we know there are approaching 7 billion people on earth (human population estimates are far less accurate than the UN would have us believe) -- all you have to do is research the numbers of any other species with which you want to compare us. However, that might not be what you should be doing: if you want to gauge environmental impact, then you need to assess biomass, being the weight of animals present: a man might, for example, eat as much and put out as much carbon dioxide as say a hundred rats, or a fifth of a cow (or whatever). It all depends why you're making the comparison. As to what fraction is 'us', we're both a herbivore and a carnivore… [cont.]

A. You need to know the catholic population in 2100 and the muslim population in 2100. To calculate the catholic pop: Pop(c,2100) = Pop(c,now) * (1 + catholic growth rate)^94 Pop(c,2100) = 51,600,000 * (1.0003)^94 = 53,075,607 To calculate the muslim pop: Pop(m,2100) = Pop(m,now) * (1 + muslim growth rate)^94 Pop(m,2100) = 8,400,000 * (1.0230)^94 = 71,217,849 Catholic pop percentage in 2100: Pop%cath = Pop(c,2100) / [Total Population] Pop%cath = Pop(c,2100) / [Pop(c,2100) + Pop (m,2100)] Pop%cath = 53,075,607 / [53,075,607 + 71,217849] Pop%cath = 42.7%

A. So are you talking about a Utopian model, a Communist model, or what? First you need to get a new species of humans. The ones I know have canine teeth, which are just wonderful for eating meat. Once you have bred these cow-people, the question is what are you going to do to keep the rest of the animal population in check? If the animal population is not to be harmed, that means that we are not using pesticides and we are letting other animals eat our crops. I'm guessing that the answer is 0.

A. It's a serious problem because of the resources they require. It's a challenge, because it's going to take decades to fix the problem, during which time the problem will get much worse. There's nothing (ethical) we can do to reduce the population, all we can do is try to reduce the fertility rate. To reduce the fertility rate, we have to improve the standard of living in LDCs, because having many children is a matter of redundancy. There are also cultural issues, e.g. "be fruitful and multiply" and some African cultures where a girl must prove her fertility before she can be married. There's a bit of a Catch-22 there though, because when the standard of living is increased, that includes increased longevity, so each person drains… [cont.]

Asked by Harry Ian John - Mon Mar 26 01:46:36 2007 - - 2 Answers - 0 Comments

A. Since you only have 2 points, I am assuming that you have to use a linear model for the population. So anyways, you assume that the population can be described by a line y = mx+b. You have to find m and b. y is the population and x is the year. to find m, you have to find the rise/run. rise is difference in population (190) and run is difference in year (10), so slope is 19. Now you have to find b, to do this you can put in any of the values you have above. y = 19x + b put in the first value: 1020 = 19 * 1996 + b 1020 = 37924 + b b = -36904. so y = 19x - 36904 put 2006 in it and you get: y = 19 * 2006 - 36904 y = 38114 - 36904 y = 1210. and put 2011 and you get y = 19*2011 - 36904 y = 1305

A. Very simple task. For poultry for example: A hen and a rooster to mate can reproduce in a month or two and can add 10 or more population at a time. Hens can lay more than 10 eggs and hatches to bring new hicks in 21 days and after a short period goes on egg laying again. The chicks grow fast and sexually matures in about 18-20 weeks. In a year, the population can grow in hundreds provide the chickens are properly cared - good environment, sufficient feedings,protected from predators,etc. For livestock: For example- Raise female cattles and breed them (artificial insemination are more successful). In a year, one female cattle delivers one or two. And the cycle goes on repeating increasing the population. For other domesticated animals… [cont.]
