All Flashcards
What is the role of forests in the carbon cycle?
Forests absorb CO2 during photosynthesis, storing carbon and reducing atmospheric CO2 levels.
How does clearcutting impact biodiversity?
Clearcutting reduces biodiversity by destroying habitats and displacing species.
Explain the relationship between deforestation and climate change.
Deforestation contributes to climate change by releasing stored carbon into the atmosphere and reducing the planet's ability to absorb CO2.
What is the significance of soil erosion in deforested areas?
Soil erosion leads to loss of fertile land, water pollution, and damage to aquatic ecosystems.
Explain the concept of interconnectedness in environmental systems.
Environmental systems are interconnected, meaning that changes in one area (e.g., deforestation) can have cascading effects on other systems (e.g., climate, water, biodiversity).
Cause: Clearcutting. Effect?
Habitat destruction, soil erosion, climate change, air pollution.
Cause: Soil erosion from clearcutting. Effect?
Polluted waterways, damaged aquatic ecosystems.
Cause: Deforestation. Effect?
Increased greenhouse gases, contributing to climate change.
Cause: Removal of trees. Effect?
Disruption of the carbon cycle, release of stored carbon.
Cause: Pesticide use in clearcutting. Effect?
Toxic chemicals added to the environment, harming wildlife.
Cause: Habitat loss from clearcutting. Effect?
Decreased biodiversity and ecosystem stability.
Cause: Decreased CO2 absorption. Effect?
Worsened air quality and accelerated climate change.
Cause: Increased CO2 in the atmosphere. Effect?
Global warming and climate change.
Cause: Selective logging. Effect?
Less habitat disruption, faster forest regeneration.
Cause: Healthy forests. Effect?
Carbon sequestration, climate regulation, biodiversity support.
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.
