To help achieve a sustained immediate environment and meet the objective of action number 5: "Healthy and sustainable environmental and social teaching and research" of the "Green Campus Ferrol Action Plan:

            The delivery of the documentary work carried out in this subject:

              - They will be requested in virtual format and/or computer support

              - It will be done through Moodle, in digital format without the need to print them.

             - If it is necessary to make them on paper:

                  - Plastics shall not be used

                 - Double-sided printing shall be carried out.

                 - Recycled paper will be used.

                 - Printing of drafts shall be avoided.

  - A sustainable use of resources and the prevention of negative impacts on the natural environment must be made.

  - It will work to identify and change gender biases and attitudes, and influence the environment to change them and promote values of respect and equality.

  - Situations of discrimination should be identified and actions and measures proposed to correct them.
