Enviornmental Science Biogeochemical cycles describe the cycling and recycling of elements in ecosystems.

• Describe the Industrial Revolution. How has it impacted the environment and the way that humans use natural resources? USE INTERNET SOURCES – and please provide • What triggered the Environmental Revolution? When did people become more focused on environmental issues? What are the goals of the Environmental Movement? Do you think that we should continue to pursue these goals? Why or why not? USE INTERNET SOURCES – and please provide • Biogeochemical cycles describe the cycling and recycling of elements in ecosystems. In your own words, describe the cycling of carbon, phosphorus, and nitrogen through both the living (biotic) and non-living (abiotic) components of ecosystems. And, describ... click for more

Biology

Rain forest species are becoming extinct at an alarming rate. You attend a fund raiser to prevent the destruction of rain forests. The head organizer discovered you have a background in bioengineering and has requested that you speak at an afternoon breakout session to help persuade people to preserve the rain forests. Create the speech you would deliver to the breakout session. The head organizer gave you the following helpful tips: include ethical, biological and economic arguments, include a discussion on the impact humans are having upon natural ecosystems, discuss how human habitation is altering the natural ecosystems. For example, the reason for floods and mudslides due to human... click for more

Algal Bloom

Human impact on the Earth's environment is poignantly demonstrated in the Mississippi River drainage into the Gulf of Mexico. Every spring, high levels of nitrogen and phosphorous wash into the river from the Midwestern United States farming region and into the northern Gulf. These nutrients supply a huge algal bloom at the water surface creating a dangerously destructive hypoxia that all but destroys the marine ecosystem. a) discuss the cycling of oxygen in the natural marine ecosystem and how this cycle is upset during an algal bloom b) pick two organisms from two different trophic levels in the marine ecosystem and explain the impact of the algal bloom on their ecology c) it ... click for more
