1.The author of this article questions
whether a world that is straining to support its current 6 billion inhabitants
will be able to support the 10 to 11 billion people that the United Nations
projects the population will grow to in the next hundred years. What kinds of changes would we need to make
now to help the Earth accommodate 5 billion more people?
2. The author references Charles C. Mann, who quoted experts who believe that in the future a “gigantic, multi-year, multi-billion dollar scientific effort, a kind of agricultural ‘person-on-the-moon project,’” may help agricultural production return to the rapid rates of growth of the 1980s. Do you think this kind of project is possible, or have we exhausted all possible technological solutions to the issue? Is the slowing of agricultural production an irreversible trend?
3. In his article, McKibben says that we are a quarter of the way into the greenhouse era, and the effects are already being felt. His ominous warnings of the immediate dangers of global warming, such as “Global warming will be like a much more powerful version of El Nino that covers the entire globe and lasts forever” should strike fear in the public. Why is it, then, that global warming and its effects seem distant to most people. How long do you think it will take for people to feel the urgency and proximity of the problem? When (if at all) will people be willing to change their lifestyles in hopes of slowing/stopping global warming?
4. McKibben says that changes need to be made in the next two or three decades to save the planet. He also says that the problems of a growing population, depletion of natural resources, and increasing output of fossil fuels and other pollutants all need to be addressed (and in dramatic ways). McKibben doubts that we will be able to live simply or efficiently enough soon enough to solve the problem. He doubts the dramatic changes that are needed will come about soon enough. Do you agree or disagree?
1. Since growth in the world harvest is slowing, food is becoming a national security issue, what are some ways in which we can fix this problem?
2. By 2050 it is estimated that 3 billion people will be born into countries already facing water shortages. Do you think that family planners will take into account population control before having a family
3. Do you agree with the author, Lester Brown, “that unless we respond to social and environmental issues that are undermining our future, we may not be able to avoid economic decline and social disintegration”
1. On page 93 Sachs points out that if the world were to continue at its current rate of carbon emissions, within 90 years carbon concentration would double to 560 ppm, generally accepted as the outer limit of risk for society. He then notes that this is if we continue what we are doing, however that developing nations will have a larger effect that will raise this number significantly if their carbon emissions aren't checked. Do you think the carbon emissions of these nations can be controlled?
2. Sachs talks of seven areas that will be impacted greatly
by climate change (rising ocean levels, habitat destruction, increased disease
transmission, changes in agricultural productivity, changes in water
availability, increased natural hazards, and changes in ocean chemistry).
Which do you think will impact human kind the most?
3. Sachs mentions that global warming caused by greenhouse gases will, in the end, have disastrous results, yet he mentions that there will be short-term positive feedback (such as leading to possible agricultural growth in places that it was previously too cold... etc.). How will these positive feedbacks affect public policy?
4. "... the disparity of treatment between Annex I parties (developed countries) and Developing Countries and the level of required emission reductions, could result in serious harm to the United States economy."- the US Senate's refusal to sign the Kyoto Protocol because of a disparity of expectations between developed and developing nations to lower carbon emissions by merely 5 percent. What will have to happen in order to make a country like the United States start to think globally? What is your reaction to this governmental decision (the only UN member not to sign the Kyoto Protocol)?
