The world demographic problems environmental problem and social problem is going to be specially severe in poor countries Explain using suitable example and provide some solutions?

The earth is a "closed system," meaning that we have to recycle or store all of the wastes we produce, and until we establish the Mars Alfalfa and Mining Colony, we only have one planet's worth of land and water to provide resources for agriculture, energy, and other needs. How well we do at these two factors-resource use and pollution management-basically depends on two factors: 1. the number of people on the planet; and 2. The average amount of resources available (per person) and the average amount of pollution produced. In basic terms, the average global standard of living is directly related to the resources available. The health of the planet (in terms of pollution) is related to how much stuff, on average, each person uses. The total impact we have on the planet, therefore, is roughly the total number of people times the average standard of living. (This basic concept is sometimes called "ecological footprint.") The world's current population is already estimated to be unsustainable at today's rates of consumption and pollution, and another 2.5 billion people over the next half-century-all rightly striving to raise their standards of living-will only exacerbate the problem. Since none of us is clamoring for a decreased standard of living, we must assume that the other side of the equation, population, is where we can most realistically expect to act to keep our Closed-System Earth in balance. Once we recognize the fact that overpopulation is a problem and that increasing standards of living around the world will add to our resource-use and pollution-management challenges, it's tempting to start thinking that disease, poverty, and premature death are unfortunate but necessary (as long as they happen to someone else, of course). We must resist any such temptation and work toward better solutions. We should: · continue to strive to reduce suffering by combating disease and poverty around the world; · continue to improve resource efficiency and pollution control so that standards of living can rise without negative impact; and · keep human population to numbers that are sustainable. On the population front, that means: · making sure people around the world have access to family planning services; · empowering women in developing countries economically, socially, and legally in a manner that results in them having an equal say (with their husbands) in reproductive decisions; · modifying school curricula to include information on population levels and implications for the future; · reforming tax laws in a way that encourages couples to have no more than two children. (They would still be able to have as many kids as they want, but the tax code would no longer subsidize more than two.) People are a good thing, but population growth without limit is not. The US and all developed countries should reinvigorate their international efforts to slow population growth. The future of the world depends on it!
