Great Barrier Reef
The Great Barrier Reef is still there, no. not yet, at least. Yet, things are not looking good and it is only still standing if you see it as a whole as opposed to the various parts that made it up. In actuality, the Great Barrier Reef has lost half of its coral since 1995. Future forecasts are not good. Some claim that if nothing is done to protect the Reef today, it will be gone by the year 2050. Others have claimed that it is now nearly hard to accomplish this.
Our oceans and the entire planet would suffer an unimaginable loss. In reality, it is composed of close to 3,000 smaller reefs. The Reef has suffered as a result of overfishing, climate change, and pollution.
The Great Barrier Reef and other reefs like it are under risk of being destroyed, which could result in up to 25% of marine species losing their habitat. Without the reef to provide protection, the local fishing industry would be decimated, and the neighboring coastal communities would experience severe erosion and weather-related damage, among other problems.
