Three E’s of Sustainability
- Environment
- Economy
- Equity
Two ways forests can help ecosystems and humans
- provide defense against floods and landslides
- store carbon, stabilize climate, provide habitats
What happens when forests are fragmented
Disrupts animal movement and ecosystem balance
What is clear- cutting and why is it controversial
Removing all trees in an area; reduces biodiversity and increases erosion
What is Integrated Pest Management (PMI)
Combining biological, chemical and physical pest control strategies
Two benefits of prescribed burning
- reduces underbrush density
- prevents uncontrolled wildfires
Farming the uses manure and avoids GMOs
Organic farming
Practice to protect soil after harvest
Planting crop covers
Smallest soul particle
Clay
Topsoil layer
A horizon
What is salinization
Salt buildup from excessive irrigation carrying salts to the soil surface
Best soil for farming
Loamy, clumpy, dark soul with neutral pH
Two techniques to prevent soil erosion
- terracing
- shelter belts (or contour farming, crop rotation
What is reclaimation
Restoring mined land to a healthy usable condition
Mineral mined for phones
Coltan
Type of deep mining
Subsurface mining
What is aquaculture
Raising fish or aquatic organisms for food
Why buy locally grown food
Reduces transportation energy (carbon footprint) and supports local economics
One risk of GMO crops
GMO genes may escape into non-GMO plants
What is food insecurity
Lack of reliable access to sufficient, affordable, nutritious food
