📚 Quick Study Guide

  • 🎣 Definition: Overexploitation refers to the unsustainable removal of wildlife or natural resources from their environment. This includes overfishing, overhunting, over-harvesting, and illegal wildlife trade.
  • 📉 Impacts: It leads to population declines, local extinctions, and disruption of ecosystems. Reduced biodiversity can weaken ecosystem services like pollination, water purification, and climate regulation.
  • 🐟 Overfishing: Removing fish faster than they can reproduce. Key examples include the collapse of cod stocks in the North Atlantic.
  • 🦌 Overhunting: Hunting animals at unsustainable rates. Examples include the near extinction of the American bison.
  • 🌳 Deforestation: Clearing forests for timber, agriculture, or development. Leads to habitat loss and contributes to climate change.
  • 🌿 Illegal Wildlife Trade: Poaching and trafficking of endangered species for their parts or as pets. Examples include elephant ivory and rhino horns.
  • ⚠️ Vulnerable Species: Species with small populations, limited ranges, or slow reproductive rates are particularly susceptible to overexploitation.
  • 💡 Solutions: Sustainable harvesting practices, protected areas, stricter regulations, and community-based conservation efforts are crucial for mitigating overexploitation.
