What is Extinction?
Extinction happens when a species—like a type of animal or plant—no longer exists anywhere on Earth. This can happen for many reasons, including:
- Habitat Loss: When animals lose their homes due to human activities, like building cities or farms.
- Pollution: When chemicals or waste from humans harm the environment, making it hard for species to survive.
- Climate Change: Changes in the Earth’s climate can make it hard for some species to adapt.
- Overhunting or Overfishing: When too many of a species are taken from the wild, they can’t reproduce fast enough to survive.
Examples of Extinct Species
- Woolly Mammoth: A large, furry elephant that lived during the Ice Age but disappeared about 4,000 years ago.
- Dodo Bird: This flightless bird was native to Mauritius and became extinct in the late 1600s due to hunting and habitat destruction.
What is Conservation?
Conservation is the act of protecting and preserving species from extinction. It involves various efforts to help species survive and thrive.
Why is Conservation Important?
- Biodiversity: Every species plays a role in its ecosystem. Losing one can affect many others.
- Medicinal Resources: Many medicines come from plants and animals. Losing species can mean losing potential cures.
- Cultural Value: Many species are important to different cultures and histories.
How Do We Preserve Species?
- Protected Areas: National parks and wildlife reserves protect habitats.
- Breeding Programs: Zoos and conservation groups breed endangered species to increase their numbers.
- Legislation: Laws like the Wildlife and Countryside Act help protect endangered species.
- Education: Teaching people about the importance of protecting the environment helps inspire action.
Tips and Tricks to Remember
- Think of a food web: Every species is connected. If one disappears, it can impact others.
- Visuals help: Draw food webs or diagrams showing how species rely on each other.
- Stay curious: Ask questions about local wildlife and conservation efforts in your area.
