  • Social Responsibility, Ecosystem Vision and Consumerism
    José Bonilla
    According to the original definition made by Tamsley in 1935, 'an ecosystem is a network of plant and animal species in equilibrium in a given region of the world, interacting with the environment'. This balance is maintained through a process of self-regulation (biological equilibrium). Human interference in natural systems tends to degrade them, due to alteration of that bala...
