Life beneath the iceberg

Among all the habitats inn the world, this is the weirdest habitat I know. An iceberg has 70% of its total volume under water so it is no surprise that icebergs provides homes for many organisms. In this article, Scientist recently found that iceberg deposits iron in the water. Since it is rich in minerals it encourages microscopic plants to grow which will attract herbivores and then attract carnivore, thus creating an ecosystem. The plants will take some carbon from the sea which will in turn remove some carbon in the atmosphere.

This articles show me that nature can crate the toughest of organisms. The plants and animals living in the iceberg have to deal will extremely cold temperatures and prevent them self from freezing. When it comes to surviving in the wild, the animals are definitely better than us humans. There are able to find such a hostile environment and yet thrive. The iceberg is going to melt someday so the habitat is only temporary but nonetheless, the organism still can benefit from the iceberg during the decades as they reproduce and adapt.

Sadly, global warming is melting the icebergs and destroying the habitats of the organisms that live in it. Since the organisms in the iceberg is helping to slow down global warming by taking in carbon, if they die the rate that the icebergs are melting will increase. So in short, global warming will cause more global warming. So as humans, we should do our best to stop global warming and preserve this unique habitat and creature before they are extinct
