Freshwater crisis is one of the most pressing problem facing humanity- it is often said that this is due to mismanagement of water. When it comes to water management, the Supply-Side and later Demand-Side approach are considered the traditional management system. However, the world is moving towards a more sustainable style of management. What is this […]
There is a species of fish (with low numbers) that is having trouble traveling up and down the river because of a dam. Chose an area that is economically depressed but has a lot of species diversity, you need to protect the species while providing jobs for locals. An animal is being poached for its […]
What would happen to an ecosystem without decomposers? since some bacteria are decomposers, which fill an important role in the food web. a. Autotrophs would take over the role of decomposers b. All levels of the food web would be affected because it would be difficult to recover nutrients from dead matter and waste c. […]
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 […]
