Introduction [4:36]
The Fondazione Corriere della Sera hosts a discussion on the planet's health, addressing anxieties related to its care. The recent COP 30 meetings aimed to control climate warming following the Paris Agreement, but progress has been insufficient, making it difficult to manage the planet's average temperature increase. The discussion features Professor Telmo Pievani, an expert in the history of biology and evolutionary theory, who collaborates with Corriere della Sera and is known for his work in science communication.
The Club of Rome Report (1972) [10:45]
In 1972, the Club of Rome, supported by the MIT of Boston and Aurelio Peccei, released a report on the limits to growth, highlighting humanity's unsustainable path regarding planetary resources. While some predictions, like the peak of oil, were incorrect, others, such as population growth and resource limitations, proved accurate. By 2024, humanity will have consumed all the resources the planet can regenerate by July 20th. In 2022, Nature published an editorial acknowledging the report's important warnings, which had been previously criticised. This highlights the self-correcting nature of science, where new data and verifications lead to revised understandings.
The Montreal Protocol (1987) [13:27]
In 1987, the United Nations signed the Montreal Protocol to address the growing concern about the ozone layer depletion. Gases like chlorofluorocarbons (CFCs) used in aerosols and refrigerators were thinning the ozone layer, which protects the Earth from harmful solar radiation. Paul Krutzen identified the mechanism behind this depletion, leading to international cooperation. The protocol mandated a transition for industries producing these gases. Despite initial resistance, over 100 countries signed the protocol. Krutzen projected that the ozone hole would recover by over 70% between 2020 and 2025 if the protocol was implemented effectively.
Success of the Montreal Protocol [19:17]
The MIT of Boston verified Krutzen's projection, finding that the ozone hole had recovered by 72% by 2024. This success story demonstrates that environmental emergencies can be resolved through collective action, policy implementation, and industrial adaptation. The economic impact of this transition was also positive, with no job losses and increased technological innovation. Companies that initially resisted the protocol eventually adapted and profited. This example shows that political direction can lead to overall well-being without economic desertification.
The Anthropocene (2002) [23:43]
In 2002, Paul Krutzen introduced the term "Anthropocene" at a conference in Mexico, defining it as a recent geological epoch dominated by humans. This term gained popularity and was considered by the International Commission on Stratigraphy for formal adoption. However, the commission decided against its introduction into geological charts due to disagreements on when the Anthropocene began. Proposed start dates included the beginning of the Neolithic era (11,700 years ago), the start of the Industrial Revolution (1800), and the year 1945 (the atomic bombings).
Criticisms of the Anthropocene [30:18]
Two main criticisms led to the rejection of the term "Anthropocene." First, it implies that all of humanity is responsible for the environmental impact, ignoring the disproportionate impact of certain populations and industrialised nations. Suggestions like "Occidentalocene" or "Capitalocene" were proposed but deemed unsuitable. Second, the Anthropocene is difficult to define precisely due to the multiple, interconnected crises, including climate change, biodiversity loss, and global inequalities. The term is considered too broad to effectively capture these complex issues.
The Great Acceleration [32:17]
The year 1945 marks the beginning of the "Great Acceleration," a period of exponential growth in human impact on the planet. Models show that various factors, such as water consumption, population growth, and greenhouse gas emissions, increased dramatically from the 1950s to the 1960s. This growth also includes positive developments like advancements in medicine, technology, and poverty reduction. However, innovations like plastics, initially beneficial, have created significant environmental problems. Microplastics are now found in human brains, raising concerns about their impact on health.
The Ambivalence of Humanity [35:52]
Humanity's relationship with the planet is ambivalent, with innovations often having unintended consequences. It's important not to reject progress entirely but to find solutions that mitigate negative impacts. Returning to a pre-industrial lifestyle is not a viable solution, as historical data shows that simpler lives often resulted in lower life expectancy and environmental degradation. Digital activities also have a carbon footprint, requiring mindful energy consumption.
Connecting Biology and Philosophy [37:37]
Professor Pievani discusses his background as a philosopher of science with a strong foundation in biology. He integrates theoretical and philosophical themes that emerge directly from scientific research. His work focuses on the ambivalence of human impact, humanity's place in nature, and future analyses, addressing these topics through scientific inquiry rather than abstract theory. Ethical considerations, such as the implications of biotechnological research like resurrecting the mammoth, are also important aspects of his work.
The Role of Technology [40:18]
Technology and innovation are crucial for addressing the ecological transition. Funding scientific research is essential, as many significant technological applications arise from basic research. Examples include genome editing for therapies, which was discovered through microbiology research. While technology is vital, it should not be an excuse for inaction. The idea of "technological solutionism," where technology alone solves environmental problems, is questionable. Geoengineering projects, like bombarding clouds with sulphur dioxide, require careful consideration of their ecological effects.
The Importance of Avoiding Extremes [46:14]
It's important to avoid the suggestion that returning to a simpler, more primitive life will benefit the environment. Historical examples show that such lifestyles often led to deforestation and other environmental problems. The transition to cleaner energy sources, like petrol, has allowed for the reduction of deforestation. Digital activities consume energy, so it's important to be mindful of their impact. The goal is to find a balance between technological advancement and responsible consumption.
Space Exploration and Technological Spin-Offs [49:07]
Space exploration has led to numerous technological advancements that have benefited civilian life. Technologies used in cell phones, communications, and material science have been advanced through aerospace research. Investments in space programs have a high rate of technological return. While returning to Mars presents challenges, the discoveries made in developing sustainable living solutions on Mars could greatly benefit life on Earth. The goal is to improve life on Earth, not to escape it.
Greenwashing and Scientific Communication [52:04]
Greenwashing is a serious issue, and consumers are increasingly sensitive to it. Generational changes in consumption and corporate reputation can drive change. The European Union's regulations on energy-efficient appliances have led to faster consumer adoption. Public tools and independent indices are needed to verify companies' environmental claims. Environmental labelling can inform consumers about the impact of their purchases. Scientific communication is crucial for explaining scientific updates and providing information for informed decision-making.
Demographic Trends and Environmental Justice [57:49]
Global demographic trends show uneven growth, with some regions growing rapidly while others experience declining birth rates. This can lead to imbalances and population movements. Flattening demographic curves may create pension challenges in the future. Environmental reforms must consider the potential disadvantages to less developed countries. Some countries, like Brazil, argue that they cannot impoverish themselves due to international regulations. China's emissions continue to increase, posing challenges for global climate goals.
Climate Finance and Global Cooperation [1:04:23]
Climate finance discussions focus on adaptation and compensation for loss and damage. These funds aim to address the inequalities and risks of growing disparities. The European Union is the only economic entity that has planned fiscal rebalancing to reduce these inequalities. The EU's potential lies in its position as the largest economic market governed by liberal democracies, which could attract investors.
Microplastics and the Future of Plastics [1:06:06]
Microplastics are a growing concern, with studies showing their presence in human brains. While the exact effects are still unknown, caution is warranted. Recycling and reuse are essential to prevent plastic from reaching the oceans. Research is focused on engineering bacteria to digest plastic. Bioplastics made from renewable resources are a promising alternative. Circular economy initiatives are gaining traction, offering future job opportunities.
Conclusion [1:11:05]
The discussion concludes with a positive and encouraging note, emphasising the importance of responsible consumption and planetary regeneration. The goal is to create a better world for future generations. The engagement and interest in courses like Circular Economy indicate a growing awareness and commitment to sustainable solutions.
