All Flashcards
Significance of clearcutting profitability?
Most profitable timber harvesting method but causes the most environmental damage.
How does clearcutting impact habitat?
Wildlife loses homes and food sources, leading to decreased biodiversity.
Clearcutting and soil erosion?
Removes tree roots, increasing soil erosion and potential landslides.
How does clearcutting affect climate change?
Releases stored carbon into the atmosphere as CO2, contributing to global warming.
Impact of clearcutting on air quality?
Fewer trees mean less CO2 absorbed, worsening air quality and climate change.
Why is pesticide use a concern in clearcutting?
Smaller trees are removed with pesticides, adding toxic chemicals to the environment.
How does selective logging impact ecosystems?
Less disruptive to the ecosystem, allowing for faster forest regeneration.
What is the role of trees in the carbon cycle?
Trees absorb CO2 during photosynthesis, storing carbon and helping regulate climate.
How does deforestation affect waterways?
Leads to soil erosion, which can pollute waterways and damage aquatic ecosystems.
What is the link between deforestation and climate?
Deforestation reduces the planet's ability to absorb CO2, increasing greenhouse gases.
How does selective logging promote sustainability?
Removes only certain trees, preserving the forest ecosystem and biodiversity.
How does group cutting promote sustainability?
Removes small groups of trees, allowing for quicker and more natural regeneration.
How can reforestation help protect the environment?
Replants trees to restore ecosystems, absorb CO2, and prevent soil erosion.
How does reducing pesticide use promote sustainability?
Minimizes toxic chemicals in the environment, protecting wildlife and ecosystems.
How does sustainable forest management help?
Balances timber harvesting with ecosystem preservation and long-term forest health.
How can reducing deforestation help?
Preserves carbon sinks, maintains biodiversity, and regulates climate.
How does promoting responsible consumption help?
Reduces demand for timber from unsustainable sources, encouraging better practices.
How can carbon offset programs help?
Compensate for carbon emissions by investing in projects that sequester carbon, like reforestation.
How does conservation of existing forests help?
Maintains carbon storage, biodiversity, and ecosystem services.
How does using alternative building materials help?
Reduces demand for timber, promoting forest preservation.
What is clearcutting?
Logging method where all trees in an area are removed at once.
Define selective logging.
Logging method where only certain trees are removed, leaving the rest of the forest intact.
Define group cutting.
Logging method where small groups of trees are removed, allowing for quicker forest regeneration.
What is habitat destruction?
The process by which a natural habitat becomes incapable of supporting its native species.
What is soil erosion?
The process by which soil is worn away and removed by wind or water.
What is carbon sequestration?
The process of capturing and storing atmospheric carbon dioxide.
What is the carbon cycle?
The biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth.
Define deforestation.
The clearing of forests for other land uses.
What are greenhouse gases?
Gases that trap heat in the atmosphere, contributing to global warming.
Define biodiversity.
The variety of life in the world or in a particular habitat or ecosystem.
