(a)
To determine: The problems that arise from population growth in less industrialized countries
Introduction:
Less industrialized countries are those where the population density is more. People live in joint families. The industrialized countries are those where the population density is less. People live in nuclear families.
(b)
To determine: The problems that arise from population growth in industrialized nations.
Introduction:
Less industrialized countries are those where the population density is more. People live in joint families. The industrialized countries are those where the population density is less. People live in nuclear families.
To determine: The greater threat of the problems that arise from population growth in less industrialized countries and industrialized nations.
Introduction:
Less industrialized countries are those where the population density is more. People live in joint families. The industrialized countries are those where the population density is less. People live in nuclear families.

Campbell Biology (11th Edition)
- (A) The above figure indicates how much biologically productive land is needed to support different activities (e.g. 'carbon' is land needed to offset carbon emissions from energy production; 'cropland' is land needed to grow crops for food). What Goes it say about the sustainability of our lifestyle? Explain. (B) The world's ecosystems provide many valuable services, that we all benefit from. Yet, these services are often undervalued and taken for granted. Why? For full credit, provide an example with at least one specific ecosystem service. (C) Humans are impacting ecosystems (and their services) in many ways, often negatively. Throughout this course we've discussed some simple actions that can be taken by individuals to help mitigate our impact on the environment. List one action and specify how it can help.arrow_forwardSome people believe our most important goal should be to sharply reduce the rate of population growth in developing countries where 97% of the world’s population growth is expected to take place. Others argue that the most serious environmental problems stem from high levels of resource consumption per person in developed countries, which use 88% of the world’s resources and have much larger ecological footprints per person than do developing countries. What is your view on this issue? Explainarrow_forward20.arrow_forward
- Lastly, notice the yellow graph for "Net Exports": in 2008 it was about +400, meaning the US exported 400 million gallons of biodiesel. But for the past several years "Net Exports" has been in negative territory, meaning that we IMPORT biodiesel from other countries! (this isn't surprising, notice that green consumption is consistently larger than blue production). The US first started importing biodiesel in the year U.S. Biodiesel Production, Exports, and Consumption Print Dow 2,500 • Production + Net Exports + Consumption 2,000 1,500 1,000 -500 -1,000 2001 Last updated October 2018 2004 2007 2010 2013 2016 Printed on: Aay 10 Millions gallonsarrow_forwardChoose the statement that is most likely made by an environmentalist rather than by an environmental scientist. "On average, 52 animal species move one step closer to extinction each year because of overpopulation and habitat destruction.” “Human population growth is a current environmental issue, as is climate change.” “When the number of existing humans exceeds the carrying capacity of the planet, we have reached the state of overpopulation.” “Citizens must take matters into their own hands and start having fewer children to reduce the world’s population, starting now.”arrow_forwardUnit #5: Ecology and Evolution World’s average ecological footprint = 2.84 gha/person (world total: 20.1 billion gha used/year) World’s biocapacity = 1.73 gha/person (12.2 billion in total) What does this mean? Under what circumstances might investigators choose to do one type of analysis versus the other (mtDNA vs. Y chromosome DNA)?arrow_forward
- Carbon dioxide and climate changed Describe 3 important changes that need to take place in order for the world to sustain up to 11 billion people by the end of the century?arrow_forward1arrow_forwardClimate change is... Question 1 options: shifts in climate means and variation that occur over periods longer than 10 years warming of temperatures over decades a phenomenon that cannot be studied and has no evidence a phenomenon that can be seen on a global level, but is not observable more locally a hoaxarrow_forward
- The purpose of making observations is to lead someone to ask a question about how or why or when something occurs in the natural world. This, in turn, stimulates the formation of possible explanations, termed hypotheses, that can be tested by collecting data from a study or an experiment. Advocates for organic farming claim that their methods result in a number of benefits to farmers, consumers, and the environment. A group of scientists is conducting a study on the benefits of organic farming. What should be the final product of the observational stage of their study?arrow_forwardThere are many different natural resources found in Florida. Florida's climate is warm and humid with an abundance of solar energy. The state is surrounded by ocean water and has fertile soil great for farming fruits and vegetables. Half of Florida's land is covered by trees, ideal for wildlife habitats and the production of paper products. Florida has a rich source of mineral deposits including: limestone, phosphate, and silicon deposits. Florida is also a source of natural gas and oil. Which of the following is a nonrenewable resource found in the State of Florida? A solar energy B pine trees phosphate orange treesarrow_forwardOpponents of alternative and renewable energy technologies argue that such technologies are expensive and contain many hidden costs. Opponents of fossil fuels and non-renewable energy technologies argue that we don't account for the hidden environmental and health costs of these technologies, which makes non-renewables (primarily fossil fuels) seem cheaper. Explore this debate by doing the following: Go to the website page: https://www.aei.org/articles/the-trouble-with-renewable-energy/ to read an article stating that renewable energy technologies may not fulfill their promise. Notice the date of the article and reflect on any change in our society's perception on this subject. Also note the author. I recommend you always do a bit of research about an article's author, because it is important to understand an author's frame of reference. Now go to the Clean Energy website to read an article about renewable energy technology:…arrow_forward
