Even today, few people measure the environmental impact of their activities. However, the diversification of pollution and the thoughtless use of non-renewable sources of energy make it indispensable to protect the environment and our natural resources. In these circumstances, PA is intended to alert the population in order to ‘save the planet’. By involving the family, the school environment, the competent authorities and the media, the partners hope to address the problem in a lateral and multi-disciplinary manner. But the main objective of PA is to make children aware of the dangers and negative consequences of certain types of behaviour on the environment.
