Australian Research Shows Warmer Water Raises Aggression In Fish
New research in Australia has shown that coral reef fish can undergo radical personality changes in warmer water, work that suggests climate change may make some marine species more aggressive. Experiments have been conducted on two species of young damselfish on Australia's Great Barrier Reef, which have shown that water temperatures can alter a fish's behavior.

There are lots of impact of global warming, the most common and important impact is causing polar ice to melt, making sea-level rise and many islands will be submerged in the next few decades. However, rising sea temperatures caused by the greenhouse effect, also caused great changes in marine species such as coral reef fish and young damselfish. These are no one would ever pay attention including me because these do not affect our lives.
In fact, the temperature rise will make these fish become more active and more likely to be the target of the predators. In other words, these fish easier to be eaten, making them more difficult to adapt to the environment, the worst of all, causing fish to become extinct.
Perhaps after a few years, the beautiful underwater scenery will no longer exist. So, go Australia now!!
