What are the two main approaches to tackle the problem of global warming and climate change?  compare the two approaches along the following dimensions:     Relative size of benefits versus costs.   Relative timing of benefits versus costs (e.g., immediate or distant). Why does this matter a lot?   Based on the current state of scientific and economic knowledge, which of the two types of policy is most likely to be cost-effective? Does it mean it will be used? Explain.

During the COVID-19 pandemic, technologies are playing a crucial role in keeping our society functional in a time of lockdowns and quarantines. And these technologies may have a long-lasting impact beyond COVID-19. Instructions: Write down at least (10) technology trends that can help build a resilient society, as well as considerations about their effects on how we do business, how we trade, how we work, how we produce goods, how we learn, how we seek medical services and how we entertain ourselves. Show and discuss on how the following platforms are functional in time of the present pandemic crisis. Answer briefly the questions based on the above discussion. Do these technological trends bring more good than bad effects to people during pandemic crisis? Should there be a limit to this kind of platform

Ecological footprint is the product of three factors: • population size, ● intensity of resource extraction, ● intensity of waste production. Each of these factors puts strain on our food systems. Search for a strategy human populations or individuals can make to reduce one of the three factors that contribute to our ecological footprint. Practice good Initiative skills as you consider strategies that could be specific to a particular part of the world. How would this help our food systems to be more effective at producing quality food?

What letter would you use to describe the exponential growth curve? c) What causes the population to slow down during logistic growth? d) The maximum population an environment can sustain is affected by environmental factors that cause the population to level out or become stable. What term is used to describe this level of logistic growth?

In terms of the human population of the Earth, what factors might impact human population growth over the next century?     Our current system of agriculture depends extensively on inexpensive fossil fuels and is likely to be impacted by climate change by the late 21st century.     Declining birthrates, especially in the developing world, are likely to bring the human race to the brink of extinction.     Soon, there will not be enough room for humans to live.     The human population will likely continue to increase exponentially for centuries.

The global human population has surpassed 7 billion, far exceeding our population’s size throughout our history on Earth. Name some specific means by which we have apparently raised Earth’s carrying capacity for our species. Do you think we can continue to raise our carrying capacity? How might we do so? What limiting factors exist for the human population today? Might Earth’s future carrying capacity for us decrease? Why or why not?

The concept of development should be broadened to include more than just one factor. briefly Discuss the factors that can be used to describe development in a nation?d) in brief Outline why the culture of a country might influence the costs, risks and benefits of doing business in that country.

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 gallons

The island of Isle Royale in Lake Superior has historically contained both moose and wolves. In recent years, the number of wolves has dwindled, leaving few predators for the moose. This has led to a large increase in the moose population on the island. The following information is from 2018. Using this information and the equation shown, the growth rate for the moose population on Isle Royale can be calculated. Based on the current population and the growth rate, what type of growth model would be expected? K = 2,000 moose N = 1,500 moose Rmax = 0.5 where: dt = change in time N=population size ax =maximum per capita growth rate of population K= carrying capacity A logistical growth model would best represent this population because the moose population will decrease over time. An exponential growth model would best represent this population because there are few predators for the moose on this island. A logistical growth model would best represent this population because the increase…
