Krill feed on microscopic phytoplankton ("phyto" - plant) that are extremely abundant in Antarctic waters due to the great upwellings of deep waters at the Antarctic convergence. These upwellings bring with them great amounts of dissolved nutrients, especially nitrate and phosphate that fertilize the microscopic but hugely abundant phytoplankton in the same way that a farmer puts fertiliser on the fields. Add to this the 24 hour intense sunlight of the summer months and the scene is set for a super-abundance of lifeType your answer here...

Who are the people killing the blue whales?
People. It used to be hunting. Now we're killing the whale's food (krill) with a combination of overfishing and warming the planet. People catch about 200,000 tons of krill per year. As if catching all the krill isn't bad enough, climate change is melting sea ice, which is where the krill's food lives. So, a warming ocean kills off marine algae, which means that krill numbers drop, which means that blue whale numbers drop.
