Antarctic marine wildlife is under threat: By Sherman Teo


Marine snails around Antarctica are being affected by the ocean’s acid. A team of researchers found that the snails' shells are being corroded. Experts say the findings are significant for predicting the future impact of ocean’s marine life. The marine snails are a major grazer of phytoplankton and they are prey to a number of higher predators. Ocean acidification is a result of burning fossil fuels. This occurs when winds push cold layers of deeper seawater from around 1,000m towards the surface layers.

In my opinion, I think that this is due to global warming. Global warming is the rise in the average temperature of Earth's atmosphere and oceans. Earth's surface temperature has increased by about 0.8 degrees Celsius .The global warming which is taking place is causing harm not only to us but to the marine life too. We depend on the marine life as much as we depend on others. The marine animals will not be able to survive and soon become extinct as they have no more food to feed on.
