Ecology Assignment

ECOLOGY: Human Activity and its Affect on The Environment

Your task is to create a Power Point presentation on an Ecology related topic with an emphasis on the affect of human activity on the Environment.

For Example:

How does human affect soil composition or soil fertility (e.g., changes to soil composition resulting from the use of different compo-stable materials, organic or inorganic fertilizers, or pesticides?

How does human activity affect water quality (e.g., leaching of organic or inorganic fertilizers or pesticides into water systems, changes to watersheds resulting from deforestation or land development, diversion of ground water for industrial uses.)

How does human activity affect the populations of organisms in terrestrial and aquatic ecosystems?

The Great Lakes constitute an important shipping route. Foreign ships often empty their ballast water, which can contain invasive species, directly into the lakes. The goby, which was likely imported in ballast water, is an aggressive fish that has taken over the spawning grounds of some native species, threatening the balance of the ecosystem.

How has the zebra mussel population in Lake Erie affected aquatic species and water quality?

How has commercial logging affected the sustainability of forests in Northern Ontario?

Landfill sites can have negative effects on adjacent ecosystems, attracting pests, leaching toxic chemicals, and producing greenhouse gases. Municipal recycling and composting programs

divert garbage, reducing the need for new landfill sites. However, many people, particularly

rural residents and those in apartment buildings, may not be included in these programs.

Note

Your presentation should be about 10 slides long and have solid information and graphics to convey the information clearly. Key points should be written in the slides and longer explanations should be given orally. Be prepared to discuss the topics and answer questions.

You must include 5 questions that can be used on a test. The students should be able to

answer the questions easily at the end of the presentation. They should cover the main ideas. These should be submitted a day before if you want to have a handout for the students. (recommended)

Your presentation should have four parts:

A Description of Issue

B How Human activity has impacted this issue.

C Questions

D References

Only good quality resources should be used. Proper internal citations must be given for all text and graphics. A bibliography in APA style will be accepted.
