Ecosystem Diversity and Climate Change

Ecosystem Diversity

• Definition: Variety of different ecosystems within a given area.
• Types of Ecosystems:
  • Terrestrial (forests, grasslands, deserts)
  • Aquatic (freshwater, marine)
• Importance:
  • Supports biodiversity, providing habitats for various species.
  • Contributes to ecosystem services (pollination, water purification).
  • Enhances resilience against environmental changes and disasters.
• Threats:
  • Habitat destruction (urbanization, deforestation).
  • Pollution (air, water, soil).
  • Climate change (shifts in temperature and precipitation patterns).
  • Invasive species (displacing native flora and fauna).
• Conservation Strategies:
  • Protected areas (national parks, wildlife reserves).
  • Sustainable practices (agriculture, forestry).
  • Restoration projects (rehabilitating degraded ecosystems).

Climate Change

• Definition: Long-term alteration of temperature and typical weather patterns in a place.
• Causes:
  • Greenhouse gas emissions (CO2, methane, nitrous oxide from burning fossil fuels).
  • Deforestation (reduces carbon storage capacity).
  • Industrial processes and agriculture (contributes to emissions).
• Effects:
  • Rising global temperatures (average increase over the past century).
  • Melting ice caps and glaciers (increased sea levels).
  • Increased frequency and intensity of extreme weather events (hurricanes, droughts).
  • Biodiversity loss (altered habitats, species extinction).
  • Ocean acidification (affects marine life).
• Mitigation Strategies:
  • Transition to renewable energy sources (solar, wind).
  • Energy efficiency improvements (buildings, transportation).
  • Reforestation and afforestation (planting trees to absorb CO2).
  • International agreements (Paris Agreement, emissions reduction targets).

Ecosystem Diversity

• Definition: Represents the variety of distinct ecosystems present in a specific region, crucial for sustaining life.
• Types of Ecosystems:
  • Terrestrial: Includes forests, grasslands, and deserts, each with unique species and ecological functions.
  • Aquatic: Divided into freshwater ecosystems (lakes, rivers) and marine ecosystems (oceans, coral reefs), vital for many species.
• Importance:
  • Underpins biodiversity, offering habitats for myriad species which maintain ecological balance.
  • Provides essential ecosystem services such as pollination for food crops and water purification for drinking.
  • Improves resilience to environmental fluctuations, such as natural disasters and climate change effects.
• Threats:
  • Habitat Destruction: Driven by urbanization and deforestation, resulting in loss of species and ecosystems.
  • Pollution: Air, water, and soil contamination that adversely affects ecosystem health.
  • Climate Change: Alters temperature and precipitation patterns, threatening ecosystem stability.
  • Invasive Species: Non-native species that disrupt and displace local flora and fauna, leading to ecosystem imbalance.
• Conservation Strategies:
  • Establishment of protected areas like national parks and wildlife reserves to safeguard ecosystems.
  • Implementation of sustainable practices in agriculture and forestry to minimize environmental impact.
  • Restoration initiatives to rehabilitate degraded or damaged ecosystems, promoting recovery of biodiversity.

Climate Change

• Definition: Refers to long-term alterations in temperature and typical weather patterns, significantly impacting various regions.
• Causes:
  • Greenhouse gas emissions, including carbon dioxide, methane, and nitrous oxide, primarily from fossil fuel combustion.
  • Deforestation, which compromises trees' ability to absorb carbon dioxide, exacerbating climate issues.
  • Contributions from industrial processes and agriculture that further elevate greenhouse gas levels.
• Effects:
  • Rise in global temperatures, with significant average increases noted over the past century impacting weather patterns.
  • Melting ice caps and glaciers leading to rising sea levels, threatening coastal habitats and human settlements.
  • Increased frequency and severity of extreme weather events, such as hurricanes and droughts, resulting in economic and environmental damage.
  • Biodiversity loss caused by habitat alteration, leading to potential species extinction.
  • Ocean acidification affects marine ecosystems, altering species interactions and food webs.
• Mitigation Strategies:
  • Transition to renewable energy sources like solar and wind power to reduce dependence on fossil fuels.
  • Enhancements in energy efficiency in sectors such as building design and transportation to lower overall emissions.
  • Reforestation and afforestation efforts to increase tree cover, enhancing carbon absorption capabilities.
  • Participation in international agreements, such as the Paris Agreement, aimed at setting and achieving emissions reduction targets globally.
