What is your community’s level of risk from a hurricane? Consider the preparedness factors into your own emergency plan. Determine what community leadership should do, and advise community stakeholders to do, before, during, and after hurricane. Evaluate the federal/national and state emergency plans for your community
This week, you have learned about our living natural resources (biota), biogeochemical cycles and how our lifestyle choices have disrupted various ecosystem services, like pollination. For this discussion, please share your observations from the Week 6 – Eco Moment (Impact of Bee Losses) Xerces site you explored. Using reliable external sites and/or information presented this […]
Given this equation (I = P x A x T), what drives environmental decline? The equation describes the multiplicative contribution of population (P), affluence (A) and technology (T) to environmental impact (I) IPAT Compare the United States with a developing country of your choice and conduct some research. (France) How do the factors given in the I=PAT […]
To explore the mechanism of eutrophication what dilemma do scientists scramble with as it is well documented that eutrophication/nutrient enrichment triggers Harmful Algal Blooms (HABs) and deteriorates water quality? To suggest solutions for overcoming challenges (possible consequences of eutrophication). Solutions can involve individual actions, economic or political strategies. # Guidelines:Read the two articles from the […]
What is the water cycle and why is it important to freshwater resources? What should society learn from the case history of the Aral Sea? What are the major kinds of water pollutants and how do they degrade water quality? Why is untreated sewage such an important water pollutant to remediate? Why are people facing […]
Introduction: In this lab, we will examine types of water pollution and cleanup measures. Materials: Two small, clear containers (approx. 16 oz) Water Food coloring Oil Coffee filter and rubber band (or powdered detergent or corn meal) Procedure: Fill both containers about one third full of water. Contaminate each glass of water with a pollutant. […]
Introduction: In this lab, we will examine the water cycle. Review the water cycle in this week’s reading before beginning. Remember, the scientific method involves observations and predictions (hypotheses). Beginning this lab with predictions will help you understand the water cycle better as well as reinforce the scientific method. Materials: Two clear zip top bags […]
A river with a flow of 22 MGD is impaired for nutrients, both nitrogen and phosphorous. The TMDL is 1,836 lb/d for nitrate. The regional department of environmental protection established a margin of safety of 72 lb/d for nitrate. Two other permits for nitrate allow waste load allocations of 355 lb/d and 277 lb/d. If […]
How do bacteria and viruses make humans sick? Why is the sky blue? Why do people grow old? Why does the moon revolve around Earth? The steps of the scientific method are the following: Observation Question Hypothesis Experimentation Data analysis Conclusion These steps are not written in stone and may vary depending on the branch […]
Lydia and Christine expected the types of microbes in the soil to change in response to the nitrogen and burning treatments because of the different aboveground plant communities and difference in soil nutrients. Soil microbial communities can change in multiple ways. First, the number of unique species can increase or decrease, measured as richness. The other way is how […]
