Human Impact Overview

Acid Rain

Define acid rain, as it is found on page 148 in the text.

Name the two chemicals that contribute most to acid rain! 1.2.

What acids do these two chemicals form when they meet with rain water?1.2.

Read the “Measuring Acid Rain” article, place a blue asterisk (on the pH scale below) under the pH of most rain water and label it “average rain water.”

Place a red asterisk (on your pH scale) under the pH of acid rain and label it “acid rain.”

Using the images below, write a couple of sentences describing the effects of acid rain on statues and forests.

Habitat Destruction

Using the handout entitled “What is habitat destruction?”Define habitat destruction.

Brainstorm all the ways you can think of that human activity causes habitat destruction.

Define biodiversity, using page 150 in your textbook.

Draw a picture showing biodiversity in a forest ecosystem.

Read the section on the handout entitled “Where is it Happening?”and give four examples of how habitat destruction is reducing biodiversity in the world.

Using page 154, define conservation.

Describe two strategies for conservation.

Describe one challenge to conservation.

Invasive Species

Using your book, page 153, define invasive species.

What happens with native species can’t compete with non-native (invasive) species?

Research, using the internet, 5 invasive plants or animals affecting North Carolina.

Biological Magnification

Define biological magnification, using page 152 in your book.

Listen to the song, “Big Yellow Taxi” by the Counting Crows. You can type in the following link OR you can search “Big Yellow Taxi with Lyrics” on You Tube. Give the line from the song that addresses each of the following environmental issues.Environmental Issue Line from Song

Ozone Layer

Go to http://www.epa.gov/spdpublc/science/missoz/index.html and click on “illustrated panels” and then “begin the story” so you can read “On the Trail of the Missing Ozone.”

1. What is the ozone layer and what is its purpose?

2. What is the biggest enemy of the ozone layer?

3. How do you abbreviate the word in number 2?

4. What types of products contain “ozone’s biggest enemy”?

5. How do these chemicals damage the ozone layer?

6. What are three things that can result from a hole (thinning) in the ozone layer?

7. Describe some ways companies are trying to reduce the use of CFCs?

Global Warming

Watch the national geographic video on global warming.http://video.nationalgeographic.com/video/101-videos/global-warming-101

1. What are the two main gases that contribute to the greenhouse gas layer?

2. Describe two effects global warming could have on our world.

Using the Global Warming Picture Provided, draw the following – a. Earthb. Greenhouse Gas Layerc. Sund. Radiation coming from the sun (orange arrows)e. Radiation absorbed by greenhouse gasesf. Deforestation, CFCs, the car, greenhouse gases and fossil fuels
