These flashcards cover key concepts from Unit 5 on land and water use, including definitions, impacts, agricultural practices, and sustainability.

What is the main focus of Unit 5?

How humans use and manage Earth's land and water resources.

What is clear-cutting?

The removal of every tree in a specific area at the same time.

Name three negative impacts of clear-cutting.

What are edge effects?

Changes in the environment that happen at the border between a forest and open land.

What is deforestation?

Changing forested land into non-forest areas, like farms or urban developments.

List two natural causes of deforestation.

• Wildfires
• Volcanic eruptions

What are two main impacts of deforestation?

1. Increased water runoff
2. Loss of habitat and biodiversity

What was the Agricultural Revolution?

A shift to new farming techniques and machinery that greatly increased food production.

How is agricultural productivity defined?

Getting more food output per unit of input (like labor or land).

What is a major benefit of drip irrigation?

It can save up to 70\% of water compared to other methods.

What is the goal of Integrated Pest Management (IPM)?

To control pests using a mix of biological, physical, and chemical tools while minimizing harm.

What are Concentrated Animal Feeding Operations (CAFOs)?

Large-scale facilities where animals are kept in confined spaces for food production.

What happens as a result of overfishing?

Natural fish populations decline and ocean habitats are often damaged.

What does an ecological footprint measure?

The amount of land and water needed to provide the resources a person consumes and to process their waste.

Name two sustainable farming practices.

• Crop rotation
• No-till farming

What does the IPAT formula calculate?

Environmental Impact (I) based on Population (P), Affluence (A), and Technology (T):
I = P \times A \times T
