Mars vs Africa

• Africa
• Water
• Planet
• Space
• Geography
• Development

This is a sarcastic joke playing on the common stereotype of Africa as a place of drought and hardship. The discovery of water on Mars is juxtaposed with Africa's perceived lack of it, creating a humorous, albeit slightly insensitive, comparison. It's a way of saying that even a faraway planet like Mars is "doing better" than Africa.
