Whales eat a lot! Well that’s an understatement considering how large they are. But have you ever wondered what comes out the other end?<\/p>\n
In this fascinating story reporter Mark Horstman discovers that whales not only play a critical role in fertilising the oceans and providing a basic food source for marine plants such as phytoplankton but in turn it’s the\u00a0phytoplankton that play a crucial role in\u00a0taking CO2<\/sub>\u00a0out of the atmosphere.<\/p>\n The Southern Ocean is a very important carbon sink for controlling the levels of\u00a0CO2<\/sub>\u00a0in the Earths atmosphere but it lacks one important ingredient to make this possible – iron. Normally an ocean is supplied with all the iron it needs from the the dust\u00a0blown off nearby land masses but the nearest landmass to the Southern Ocean is\u00a0Antarctica, frozen solid under an ice sheet! So how on earth are you going to get the much needed iron way down south?<\/p>\n Follow the below link to view the full story.<\/p>\n
