I have four big questions at hand and need to see if I can get your insight as follows: Again, thank you for an outstanding response from your team on the previous questions as well!!! 1. Describe why finding solutions to environmental problems is so difficult. Do you think it has always been as complicated? Please explain why or why not you feel as such. 2. List two key environmental issues for each in the following regions: the wilderness North, the Agricultural Middle, the forested West, the dry West, the Great Lakes/Industrial Northeast, and the South regions of the United States. Additionally, find additional information on one of these regions and explain one of the issues in depth for just one of the regions listed above. Explain why you chose this region and this issue to further research. 3. Define environment and ecosystem and provide examples of these terms from your region. Make sure you explain the difference between these terms in your response, and be able to relate these words to examples wherever you are living right now. Try to think of at least a couple of examples for each term. 4. Select a local environmental issue. Is there a solution to the problem? Please include  how politics, ethics, and economics are involved in this issue (if at all). If possible, find an outside source of information to use.

Humans raising cattle for food is what kind of relationship? Please explain why you think it is this kind of relationship. Describe the carbon cycle and the nitrogen cycle. Please include all-important components of each of the cycles. Analyze an aquarium as an ecosystem. Identify the major abiotic and biotic factors. List members of the producer, primary consumer, secondary consumer, and decomposer trophic levels. Even before humans entered the scene, many species of plants and animals were extinct and new ones had developed. Why are we even concerned about endangered species given the fact that species have always come and gone? In fact, why should we be more concerned now than even one hundred years ago?

These questions deal with our ecology and how it affects us on a daily basis. How does a climax community differ from a successional community? Please give an example of each type of community in your response to this question. List three characteristics typical of each of the following biomes: tropical rainforest, desert, tundra, taiga, savanna, grassland, and temperate deciduous forest. In addition, please list some examples of organisms that inhabit each of these types of biomes. How does altitude affect the kind of biome present? List three differences between freshwater and marine ecosystems. What do you think about restoring ecosystems that have been degraded by human activity? Should it be done or not? Why? Who should pay for this reconstruction? We humans seem to deny our place in the "natural world." Do you see human-made changes as part of the natural world? How do you make distinctions between human-made changes and natural changes? What lines do you draw to separate acceptable human changes from unacceptable ones?

Humans move around a lot, and intentionally or not, introduce species to new habitats that these species had not formerly inhabited. Describe what you think the effect of introduced species might be on the new ecosystems. Please explain why.

All the following questions relate to ecology: 1. How are biotic potential and age distribution interrelated? Hint: Relate ages of organisms to their biotic potential. 2. Why do populations grow? What factors help to determine the rate of growth? 3. List four factors that could determine the carrying capacity of an animal species. 4. All successful organisms overproduce. What advantages does this provide for the species? What disadvantages may occur? Please list at least 2 advantages and at least 2 disadvantages. 5. Why do invading species, which can survive in a new environment, often show exponential growth rates soon after they are introduced to that environment? 6. Why do people who live in overpopulated countries use plants as their main source of food? 7. List five changes you might anticipate if the world population were to double in the next 50 years. Explain why you think each change will take place. 8. Which three areas of the world have the highest population growth rate? Which three areas of the world have the lowest standard of living? 9. Population growth causes many environmental problems. Identify some of these problems. What role do you think technology will play in solving these problems? Are you optimistic or pessimistic about these problems being solved through technology? Why?
