Millions of lives are at stake in the drought and famine in East Africa. The UN also declared an emergency humanitarian crisis throughout the Horn of Africa. So how is the world reacting? To find out I turned to Twitter to see who is tweeting about famine in Africa. I have mapped out the tweets from Central/South Africa, Eastern/Western United States and Europe. The map animates through the latest tweets. You can select the tweets from different regions listed on the left (in the map view).
