In 2025, the International Conference on Biology and Earth Sciences will be held in Kunming, China, known as the "Spring City". The conference aims to gather top scientists, researchers, and industry experts in the fields of biology and earth sciences from around the world to explore the latest developments in these two important disciplines and their impact on key issues such as environmental protection and sustainable development. Kunming, as a city with abundant natural resources and diverse biological populations, provides an ideal background for hosting this conference focused on the natural world. This place not only has beautiful natural scenery, but also carries rich ecological and cultural traditions, making it an ideal place to explore biology and earth sciences. This conference will conduct in-depth discussions on multiple core themes, including ecosystem service functions, climate change impacts, biodiversity conservation, geological processes, and environmental change. The conference has various forms, including keynote speeches, thematic seminars, poster displays, and field visits, aiming to promote knowledge exchange and technical cooperation. The specially established Young Scientists Forum will provide a platform for young researchers to showcase their research results and encourage the new generation of researchers to continue exploring the mysteries of nature. In addition, there will be a dedicated technology exhibition area where exhibitors can showcase the latest research tools and technological solutions, promoting direct dialogue and cooperation between industry, academia, and research. This conference not only focuses on breakthroughs in basic scientific research, but also attaches importance to the transformation and development of these research results in practical applications, committed to promoting solutions to global challenges such as ecological protection, rational utilization of resources, and addressing climate change. Through this conference, we hope to inspire more ideas about environmental protection, strengthen international cooperation, and jointly face the challenges brought by global environmental change. We sincerely invite professionals engaged in biology and earth science research from around the world to participate in this grand event, share the latest research results and development trends, and jointly explore future development directions.
