The great barrier reef under threat
the great barrier reef😢
the great barrier reef
if you don't save now then the problems will become worse!!!!!!! Also, if that happens then it will be a problem because it is one of the biggest tourist attraction.
coral bleaching
as you can see in the picture aside, the coral is being bleached due to the climate change the algae had died so the coral has nothing to eat so the result of no algae means the coral has no food and is being bleached. More than 95 percent of the reef has been bleached!
Overfishing
Overfishing has caused more fish to die as you can see people catch too many fish. Which causes fish extinction.
spiky starfish
this is another concern that kills many species of coral it sticks on the coral and eats it. Scientists have tried to inject poison into the starfish to kill the starfish. But fertiliser which sometimes goes in the water and helps the starfish grow.
