Reading - The great Barrier Reef

This week for reading we were reading about the Great Barrier Reef. Our task was to write three things we learned about the reef that we didn't know about. I haven't really done anything about the great barrier reef so it was all kind of new to me. 

#1. I learnt that the great barrier reef is approximately 500,000 years old

#2 The great barrier reef has about 1,500 different and living species in it.

#3 I learnt that climate change could be a huge part of the reef slowly destroying.
