Why Is This Island Disappearing?

The video discusses the shrinking of Hoboro Island, which is being eroded by crustaceans called Sphaeroma sieboldii. These creatures bore into rocks, accelerating natural erosion. The video explores how erosion affects ecosystems globally, with examples from Malaysia and coral reefs. It highlights the role of bioeroders like isopods and parrotfish in breaking down materials. The impact of climate change on erosion, including ocean acidification and severe weather, is also examined. Human activities and invasive species further influence erosion processes.

What is causing the erosion of the Japanese island discussed in the video?

• Wind and waves

• Volcanic activity

• Human activities

• Small crustaceans

Which organisms are mentioned as contributing to global erosion?

• Only microbes

• Animals, plants, and microbes

• Only plants

• Only animals

What is the impact of isopods on sandstone in Malaysia?

• They cause no significant change

• They bore deep holes and remove surface material

• They strengthen the rock

• They create new rock formations

Which organisms are known to erode coral reefs?

• Sharks and rays

• Turtles and crabs

• Dolphins and whales

• Sea urchins and parrotfish

How does climate change affect coral reef erosion?

• It has no effect

• It reduces erosion

• It increases erosion

• It stops erosion completely
