Document Summary

What are canada"s plans to reduce greenhouse gas emissions produced from alberta"s oil. According to mcquaig linda in her article, oil sands make canada complicit in global. Warming , canada does not take any actions to reduce the greenhouse gas emissions (ghg) produced from the oil sands in northern alberta. In 2002, canada signed the kyoto agreement committing to reduce ghg emissions (mcquaig 2005). In contrast to what authorities have claimed, ottawa and the government of alberta greatly support the oil industry. They want to triple the production to 3 million barrels a day seeing that the oil prices have continued to increase (mcquaig 2005). The oil sand industry mentioned they would help reduce ghg however, this would take decades considering that alberta"s reserve is similar in size to saudi. Arabia"s reserve yet not as easily accessible (mcquaig 2005). Canada, the oil industry in alberta will soon be exporting most of its oil to the united states.

What are some of the strategies scientists and engineers have proposed to reduce warming without reducing emissions of greenhouse gases? Why are they controversial ?

Global Warming: Carbon Dioxide and its Effects on Agriculture Many scientists understand that earth is getting warmer and that the cause could be an intensified greenhouse effect resulting from increased CO2 emissions from industry, vehicles, and the burning of forests. Increased carbon dioxide levels will also affect the nutritional quality of many crop plants by decreasing protein content and increasing weed growth. Global warming could influence agriculture and perhaps even completely melt polar ice, leading to flooding of coastal regions. Over 90% of scientists now agree that global warming is occurring. In response to this potential threat, several European countries, the United States, Australia, and New Zealand have made a commitment to significantly reduce carbon dioxide emissions. However, some countries oppose taking strong actions at this time and the U.S. has only met a relatively small proportion of its commitments. Several reasons are cited. First, some experts think the apparent warming trend may be just a random fluctuation in temperature. Second, if the temperature increase is real, some argue that it has yet to be proven that the cause is increased CO2. However, regardless of the effects on climate change, the carbon fertilization effect of increased CO2 levels is affecting crops each year. Some believe it would be difficult to cut CO2 emissions without sacrificing comfort, convenience, and economic growth. Carbon Dioxide as a Greenhouse Gas: http://www.epa.gov/climatechange/ghgemissions/gases/co2.html Effects of Carbon Fertilization of Crop Plants: http://www.news.ucdavis.edu/search/news_detail.lasso?id=9479 http://news.illinois.edu/news/14/0507CO2_AndrewLeakey.html http://news.heartland.org/newspaper-article/2013/10/29/carbon-dioxide-emissions-stimulating-15-trillion-crop-production Please consider and reply to the questions below: Do you think we should have more evidence that greenhouse warming is real before taking action? Or is it better to play it safe and act now to reduce CO2 emissions? The evidence of carbon fertilization of crop plants is readily available and accepted. Crop plants are producing less seed and less protein. Weed plants are overgrowing crop plants and reducing annual yields. Should we take action now to reduce CO2 emissions in order to prevent the loss of agricultural output and nutritious crops?

Written Assignment: Biology and Technology in the Real World

Addresses course outcomes 1-4:

recognize and explain how the scientific method is used to solve problems

make observations and discriminate between scientific and pseudoscientific explanations

weigh evidence and make decisions based on strengths and limitations of scientific knowledge and the scientific method

use knowledge of biological principles, the scientific method, and appropriate technologies to ask relevant questions, develop hypotheses, design and conduct experiments, interpret results, and draw conclusions

1. Select one of the topics listed below.

2. Find at least three information sources related to the topic. You can find assistance with searching for articles at the UMUC Library Subject Guides at http://libguides.umuc.edu/science.

3. Write a 750-1500 word paper, excluding references and title page. You must read the information sources that you find and summarize the information in your own words, addressing each of the questions and expectations for your chosen topic. Extensive quotes from the article are discouraged. Use APA style for citing references, see https://www.umuc.edu/library/libhow/apa_tutorial.cfm

4. Post your assignment to the Assignment folder by the due date listed in the course schedule.

Topics (select one from the list below or from the expanded list of topics posted on November 16th in the announcements section)

a) Genetically modified organisms (GMOs). What is the purpose genetic engineering of crop plants and domestic animals? Briefly explain how GMOs are created. What foods in your supermarket contain GMOs? Are foods that contain GMOs safe for human consumption? What types of regulations exist for these foods? Clearly explain your reasoning for each answer.

b) Stem cells. Your friend had a spinal cord injury after a bad car accident. The medical team has decided that he is a good candidate for a clinical trial using stem cell therapy. Your friend has not had a biology course since high school, so you decide to write him a letter sharing your knowledge of stem cells. Include in your letter a description of the biology of stem cells and how these cells are unique from other cells. Contrast the different types of stem cells, including pros and cons of each. Explain how stems cells are can be used to treat diseases and injury, with special focus on spinal cord injuries. Conclude with your own opinion.

c) Fracking (hydraulic fracturing) and tar sands (oil sands). With society's dependence on nonrenewable fossil fuels, the oil & gas industry is turning to the use of hydraulic fracturing and tar (oil) sands to extract natural gas and oil respectively. A friend asks you "What's all this controversy in the news about fracking and tar sands?" Briefly explain to your friend how hydraulic fracturing and tar (oil) sands are used to obtain these fossil fuels. Then, in more detail, describe the environmental problems that may result from these processes and why they are controversial. Issues that may be addressed involves, but are not limited to, water, air and soil pollution, effects on human health, effects on other species and natural ecosystems. Finally, give your opinions on possible solutions to these environmental problems, with your reasoning backed by the references that you studied.
