The defense of the environment needs us all! Therefore, from  GEN-GOB we want to thank all the people that have participated voluntarily in the study, dissemination and defense of the environment, during more than 30-years of life of the association. Thanks to your help and involvement, and the infinity of people and groups, we have achieved our greatest successes. At the same time, we want to thank all the volunteers that have recently joined the project “The Sea, a shared responsibility”. And we want to encourage those who still are not volunteers to collaborate in the different lines of work.
