an Impact on the Environment Directions: Read Human Impact on the Environment and then answer the following questions. 1. Use context clues to define the following terms: Detrimental - __ Overfishing - __ Native species - __ Greenhouse gas - __ Pesticide - __ Herbicide - __ Sewage - __ Deforestation - __ 2. What are two negative (bad) consequences of overfishing? 3. What medicine comes from the Himalayan Yew tree?What does it treat? 4. Why are elephants killed? 5. Zebra mussels belong in the waters of Europe.How did they get to the United States? 6. What is the difference between a native species and an invasive species? 7. Carbon dioxide is a natural, normal part of Earth's atmosphere. Explain why it is a concern for climate change. 8. Why are fossil fuels burned?

## Step 1<br />The first part of the question asks for the definitions of several terms related to environmental science. These terms are:<br />- Detrimental: This term generally refers to something that is harmful or damaging.<br />- Overfishing: This term refers to the practice of catching too many fish from a body of water, leading to the depletion of the species.<br />- Native species: These are species that naturally occur in a specific region or ecosystem.<br />- Greenhouse gas: These are gases that trap heat in the atmosphere, contributing to the greenhouse effect.<br />- Pesticide: This is a substance used to kill pests.<br />- Herbicide: This is a substance used to kill unwanted vegetation.<br />- Sewage: This refers to waste water and excreta from homes and industries.<br />- Deforestation: This is the process of clearing trees and vegetation from an area.<br /><br />## Step 2<br />The second part of the question asks for two negative consequences of overfishing. These could include:<br />- Depletion of fish populations, leading to fish for commercial and recreational fishing.<br />- Disruption of the marine food chain, as certain species are removed from the ecosystem.<br /><br />## Step 3<br />The third part of the question asks for the name of a medicine that comes from the Himalayan Yew tree and what it treats. The answer is Taxol, which is used to treat various forms of cancer.<br /><br />## Step 4<br />The fourth part of the question asks why elephants are killed. This is typically done for their ivory, which is used in the production of various goods.<br /><br />## Step 5<br />The fifth part of the question asks how zebra mussels, which are native to Europe, ended up in the United States. They were likely introduced to the United States through ballast water from ships.<br /><br />## Step 6<br />The sixth part of the question asks for the difference between a native species and an invasive species. A native species is one that naturally occurs in a specific region or ecosystem, while an invasive species is one that is not native to a specific location and has a tendency to spread, which can cause damage to the environment, human economy, or human health.<br /><br />## Step 7<br />The seventh part of the question asks why carbon dioxide is a concern for climate change. While carbon dioxide is a natural part of the Earth's atmosphere, an increase in its concentration due to human activities is leading to global warming and climate change.<br /><br />## Step 8<br />The eighth part of the question asks why fossil fuels are burned. Fossil fuels are burned to produce energy, which is used to power various activities such as transportation, heating, and electricity generation.
