Failed cleanup of Gulf of Mexico
Due to an accident at BP, a lot of oil unintentionally ended up in the sea near the Gulf of Mexico. In order to ensure that this would disappear more quickly, chemicals were thrown into the water that were supposed to make the oil droplets smaller and speed up the decomposition process. Unfortunately, the chemicals had the opposite effect: the chemicals caused microorganisms to flourish and drive out the microorganisms that were breaking down the oil.
The leaning tower of Pisa
When the construction of the tower of Pisa began in 1173, not everything went smoothly. The tower began to lean more and more. The project was halted several times and the new floors were built straight, making the tower not only leaning, but also crooked. The leaning makes the tower very unique and therefore the tower has been a tourist attraction for years, bringing in a lot of money.
