As the 21st century progresses, it becomes increasingly clear just how many challenges the world faces faced are numerous. Among these concerns, environmental issues, particularly ozone depletion and climate change, are at the forefront. Although the international community has had exceptional success in its fight to reduce the production and consumption of chlorofluorocarbons (CFCs), the organic compounds that contribute to the ozone problem, its efforts to combat climate change have yielded far less. of results. A number of factors that facilitated the ozone regime or campaign do not apply to the climate change regime. The issue of limiting CFCs was much less politically and economically fraught than that of reducing greenhouse gases (GHG), responsible for the greenhouse effect and the resulting global warming. Climate change has been called the ultimate "tragedy of the commons", an important metaphor in economics that helps explain why this topic is still at the center of heated debate and has not yet been resolved in a manner similar to that of the ozone problem. Before analyzing why climate change is perhaps the best example of a “tragedy of the commons” situation, it is necessary to begin with an explanation of this concept. In a “tragedy of the commons” situation, there is a shared resource. This resource is limited, which poses a problem for each member of the collective property, because each individual is concerned with promoting their own interests. This interest is above all to make the best possible use of the resource. If each member of the group must act in this way for their own benefit, the resource will be depleted to the point where it is no longer sustainable. Alt...... middle of paper ...... profit. Increased government accountability starts at the local level, when the public is convinced of the seriousness of the problem and the importance of finding solutions. Change does not happen quickly or smoothly, but the fear of a path strewn with pitfalls can no longer prohibit the implementation of any action. If no one chooses short-term sacrifices for long-term benefits, the resource will eventually no longer be able to sustain us. Since the resource, or “commons,” at stake affects the entire planet, the entire population must work as a team to make decisions. The stakes are high for non-cooperative states that go against the will and, therefore, the best interests of the international community. Global collaboration depends on convincing world leaders to take the threat seriously and fairly share the burden of change..
