The conference is being organised with constant concern about the human impact on the environment, not just historical but present.  It is our aim that this meeting has an ecological footprint as low as possible and accordingly the conference participants' identifiers, fully recycled and customised, were made by students of Helen Keller school within the project Ecologic School, (Projecto Trilho I Projeto Eco-Escola) and coffee breaks will be supported by BioMimos.
