More Than Just Survival
Current Situation – Extinction Risk
Number of species
~9 million species (estimated)
Many not yet identified
Extinction rate
0.01–0.1% per year
900–9,000 species annually
Not inevitable
Some species brought back
Nature provides medicine
Causes of Extinction
Hunting
Example: gray whale
Nearly extinct → protected → recovered
Habitat destruction
Farming
Resource extraction
Human population growth
Genetic Risk
Low numbers → low gene diversity
Weaknesses develop
Harder to survive
Example: Arabian gazelle
Protection efforts
Increase gene variation
Improve survival chances
Protecting Ecosystems (Not Just One Species)
Food chain connection
Ecosystem interdependent
Damage affects many species
Example: Amur tiger
Protected species
Restricted hunting of prey
Numbers recovered
Importance of Ecosystem Balance
Mountain gorilla
Habitat protection
Prevent extinction
Bees
Pollination
Food shortages if lost
Unexpected Environmental Benefits
Whales & carbon cycle
Whale waste → phytoplankton
Phytoplankton absorb CO₂
Hunting impact
Fewer whales → less carbon absorption
Climate change worsened
Economic Solution – Ecotourism
Economic boost
Jobs (tour guides, local businesses)
National parks created
Example: Costa Rica
Reduced environmental damage
