<p>Dear editor,</p><p>The paper "Valores Ambientais como Mediadores da Influência de Altruísmo e Frugalidade Sobre o Sacrifício Material" is a quantitative study, with a sectional design, where we investigated the relationship between environmental values and material sacrifice as a consumer value, plus how the prior is a mediator variable of the impact of altruism and frugality over sacrifice. It is an important topic as many authors try to think of a way to understand the bridges that could be built between frugality and green values as part of ecofriendly behaviors. It is critical that people learn to use any item they have in a resourceful way, but not just for the sake of resources itself (as the original definition of pure frugality), but for the sake of the environment. </p><p>We hope that the editorial process also helps us to develop even more our conclusions. </p><p>Kind regards,</p><p>Pedro P. Pires.</p>
