The idea of interconnectivity was among the most significant lessons learned during the summer program. One field cannot adequately handle issues like climate change, biodiversity loss, environmental degradation, food shortages, and new health risks. Researchers from a variety of disciplines, including medical, biology, environmental sciences, agriculture, economics, social sciences, and politics, must work together to address these issues. These viewpoints were brought together in a great way by the Planetary Health Summer, which also inspired us to create a more comprehensive, systems-level understanding of research.

An especially valuable component was the training in business development and innovation. For future researchers, scientific expertise alone may not always be sufficient to translate research findings into meaningful societal impact. Understanding business development enables academics to identify prospects for innovation, possible stakeholders and users, explain the value of their research, and investigate methods for transforming scientific discoveries into practical solutions. These skills are especially critical for researchers who plan to pursue entrepreneurship, industry engagement, technology transfer, or impact-oriented research in the future.

Another significant benefit of the program was the ability to learn from professionals and engage with other participants. Lectures, discussions, group activities, and collaborative exercises provided opportunities to exchange ideas with people from various academic and professional backgrounds. Such encounters are particularly beneficial to young researchers because they foster communication, teamwork, critical thinking, networking, and multidisciplinary collaboration abilities. Planetary Health reminds us that scientific research is embedded in a broader social, economic, and environmental context. It inspired us to consider how our research may serve society, how innovations can be applied in a sustainable manner, and how scientific solutions can address real-world problems.

The summer programme was also valuable from a personal perspective. The engaging sessions and collaborative atmosphere made learning enjoyable, while the opportunity to exchange ideas openly created a strong sense of community among participants. We all thoroughly enjoyed the experience (especially the trip to the Seili) not only because of the knowledge we gained but also because of the friendships, discussions, and shared experiences that developed throughout the programme.
