Microsoft founder Bill Gates released a roar of mosquitoes at the participants of the TED conference, reports AFP. In this way, he decided to draw attention to the spread of malaria.

Speaking at TED, Gates said malaria was spread by mosquitoes, and he brought several of these insects with him. He then opened a bowl of mosquitoes, saying that there was no reason only poor people should get malaria.

After a minute’s pause, during which mosquitoes flew through the hall, Microsoft founder said that the insects he released were not malaria carriers.
