Most of the scientific community claims that the planet’s sustainability is seriously threatened. Industrial processes associated with the use of natural resources are accompanied by an evident deterioration of the environment . Precautionary Principle
Scientists are aware of most of the harmful effects, but sometimes science lacks the necessary explanations. For this reason, it is advisable to adopt precautionary measures with which it is possible to act in favor of the planet.
A key item on the international agenda
At the “Earth Summit” promoted by the UN and held in the Brazilian city of Rio de Janeiro in 1992, the Precautionary Principle was established. According to him, if there is a clear threat or irreversible damage that threatens the environment , the absence of scientific evidence cannot represent an obstacle to delaying measures that prevent deterioration and environmental degradation.
Consequently, the precautionary principle requires the cancellation of all activities that pose a threat to the environment, even in cases where scientific evidence is not conclusive. Precautionary Principle
A principle that represents a call to responsibility for society as a whole
The precautionary principle is not simply a specific item of an international summit, but a message that reminds us of the role of society in combating the threats that endanger the sustainability of the planet.
In this sense, we must all prevent the possible harmful effects of our actions. Thus, before using a new technology or an innovative chemical process, all individuals have a responsibility to examine other possible alternatives, including the alternative of not acting.
This precautionary principle seeks to prevent scientific limitations from becoming an alibis for lack of action in the environmental field. Precautionary Principle
The problem of scientific uncertainty
Scientific activity must be guided in the search for evidence and certainties. However, this goal is not always achieved. Uncertainties in the field of sustainability of the planet should not lead to passive attitudes.
The precautionary principle is intended to act as a brake in extremely serious situations. Thus, if human action causes an obvious deterioration in the environment, we should not wait until scientific investigations demonstrate the causal relationship between the action and the damage caused.
When something causes obvious and irreversible damage to health (for example, the use of asbestos in construction), it does not seem plausible to say that asbestos should not be banned because the causal relationships between this material and cancer or other diseases are still unknown.
