Declining biodiversity confronts every region of the world. Below are select discussions of current challenges to biodiversity within each of six regions of the world.
The Great Green Wall is being designed to prevent further desertification of the Sahel region in Northern Africa. Learn about the progress being made on this project.
Habitat loss and construction of dams that lead to habitat fragmentation threaten China’s biodiversity. Wendy Wright, a senior lecturer in biology and ecology, is studying the results of dramatic ecological changes on bird species. Read more here.
There are 943 plant and animal species in England that have been targeted under the Species Recovery Programme to preserve biodiversity. Check out the species of the month.
The New York Times reports that global climate change will have adverse effects on nearly half of North American bird species. Take a look at how the three-toed woodpecker, the northern hawk owl, and other birds will struggle to survive.
A report in Science magazine referenced in this National Geographic article suggests that over 33,000 square miles of forest have been preserved in Brazil since 2004. Read more about how farmers and ranchers have preserved biodiversity and reduced carbon emissions by decreasing deforestation.
An invasive species originally known as “the mad one” was introduced to the Rajasthan Desert in India from Mexico in the 1930’s. Read this article from The Guardian newspaper to see how this species is impacting the restoration of natural biodiversity in the desert today.
Questions to Consider
Imagine you are traveling to a world region that you have never visited. You are taking the trip to learn about trouble spots of declining biodiversity from experts and activists.
- Some homework before the trip: go on the web and learn about a current problem of declining biodiversity in one of the countries of the region.
- When you arrive, what is the first question you want to ask the experts and activists from this country about their biodiversity problem?
- If one of the experts asks you if your country also has a problem with declining biodiversity, how would you answer? If ‘no’, why not? If ‘yes’, why and what is being done about it?
