• How do coral reefs get harmed by feeding on plastic?
Due to effect of UV rays coming from sunlight, plastic products get broken down into smaller
pieces called micro plastics, when coral reefs filter the seawater to get their food; they ingest
these micro plastics, so coral reefs get harmed.
• What should we do to reduce plastic?
➢ People should recycle the plastic products instead of throwing them in the sea.
➢ Replace the plastic forks with wooden ones
➢ Replace the plastic bags with cloth ones
➢ In Egypt, coastal communities near the coral reefs applied a new way of life known as a
(Zero plastics).
• Habitat restoration:
It the process of returning a habitat back to its natural state before harm was done.
• Nursery
Is an area in the sea, where scientists take care of small pieces of coral until they grow up
and can be moved back to the sea.
• Rebuilding coral reefs:
One example of restoring a habitat is a coral
reef rehabilitation project that happens in the
Arabian Gulf, where Scientists collect small parts
of different coral species and they move them to
a nursery protecting coral reefs from plastic
pollution.
