Countries are missing out on making loads of money from tourists because they're killing off their sea turtles, according to researchers.
They studied sites in Africa, Asia, Latin America and the Caribbean. They found that many turtles were killed for their meat, leather and eggs.
But keeping the creatures alive is much more profitable because of the growing trend for turtle-spotting tours.
They bring in £975,000 per year, while turtle products bring in just £332,000.
