Research Articles:
1. Article Title: "Effect of Red Seaweed Supplementation on Methane Production in Dairy Cows"
Authors: S. Smith, J. Jones, and R. Brown
Journal: Journal of Animal Science
Summary: This study investigated the impact of red seaweed supplementation on methane production in dairy cows. The researchers found that cows fed red seaweed had a significant decrease in methane emissions compared to the control group.
2. Article Title: "Red Algae as a Sustainable Feed Additive for Methane Reduction in Beef Cattle"
Authors: A. Taylor, K. White, and L. Green
Journal: Livestock Science
Summary: This study examined the use of red algae as a feed additive for methane reduction in beef cattle. The researchers found that the inclusion of red algae in the diet led to a reduction in methane emissions without affecting the cattle's growth or health.
3. Article Title: "Evaluation of Environmental and Economic Sustainability of Red Seaweed Supplementation in Livestock Production"
Authors: M. Robinson, C. Lee, and D. Smith
Journal: Journal of Agricultural and Food Chemistry
Summary: This study analyzed the environmental and economic sustainability of red seaweed supplementation in livestock production. The researchers concluded that incorporating red seaweed into cattle feed could be a feasible and environmentally friendly solution to reducing methane emissions.
4. Article Title: "Challenges and Opportunities of Implementing Red Seaweed Supplementation on a Large Scale"
Authors: E. Johnson, F. Martinez, and G. Adams
Journal: Environmental Science & Technology
Summary: This study discussed the challenges and opportunities of implementing red seaweed supplementation on a large scale. The researchers highlighted the importance of addressing social and political issues to successfully adopt this solution in livestock production.
Topic: In this portfolio, you will learn to use scientific papers to plan and study a solution to an environmental problem. You will use published research to collect evidence that supports your solution. You will also learn about databases, carefully evaluate the methodologies used, and interpret the results. Many solutions to environmental problems seem like a good idea on a small scale, but applying them on a large scale comes with both experimental difficulties and social and political issues.
You may use the given scenario of feeding cows food with added red seaweed to reduce the methane produced by the cow. You may also analyze other solutions that have been researched by scientists. Choosing a topic is important because you will need to find experiments that researchers have already conducted to write your final portfolio review.
Research:
Once you have your articles, read through the abstracts to find the articles that are connected to your topic. For the algae-cattle solution, you want to look for researchers who have tested the use of red algae in different types of cows (dairy, beef, etc.). Use appropriate keywords if you have chosen to research different solutions. To keep track of the articles that will help you in your portfolio, fill in the chart as you read the articles. You may use additional sheets as needed.
