All Flashcards
How does selective logging promote sustainability?
Selective logging minimizes habitat destruction and allows for faster forest regeneration, promoting long-term forest health.
How does group cutting promote sustainability?
Group cutting allows for faster forest regeneration and is a more strategic and sustainable approach.
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.
What are the effects of clearcutting on local water quality?
Increased soil erosion leads to sedimentation and pollution of waterways, harming aquatic ecosystems.
How does deforestation contribute to increased greenhouse gases?
Deforestation releases stored carbon into the atmosphere as CO2, increasing greenhouse gas concentrations.
What is the impact of habitat destruction on wildlife populations?
Habitat destruction leads to loss of food sources, shelter, and breeding grounds, causing population declines and potential extinctions.
What is the effect of clearcutting on soil stability?
Removal of tree roots leads to increased soil erosion and decreased soil stability, increasing the risk of landslides.
