The work of the Mexican scientist Mario Molina, Nobel Prize in Chemistry in 1995, has been vital for the care of the ozone layer, which protects our planet from ultraviolet rays and at BBC Mundo we recommend you send him your questions.

A United Nations study found signs of recovery in the ozone layer.
The scientist identified that chlorofluorocarbons, known as CFCs and found in aerosols, in air conditioning and refrigeration systems, are a threat to the environment.
Along with his colleagues Paul J. Crutzen and F. Sherwood Rowland, Molina published the results of his research in 1974. Thanks to him, in 1987 a global agreement was reached to prohibit the use of these substances.
Four decades after that and after years of reduction, study signs were found for the first time that the ozone layer is beginning to recover.
At BBC Mundo we will speak with the Mexican scientist and we want you to be part of the interview.
