Biosphere 2, located in Oracle, Arizona, is a unique greenhouse that includes various ecosystems such as a rainforest and a miniature ocean. Built in the late 1980s and early 1990s, it served to investigate the feasibility of human survival in a closed environment. Eight individuals lived in the structure for two years, growing food and conducting experiments. However, challenges including dropping oxygen levels and personal conflicts led to the project's controversies. Now focused on ecological research, Biosphere 2 operates as a laboratory under Columbia University to explore sustainability and environmental science.
Biosphere 2, a massive greenhouse in Oracle, Arizona, features diverse ecosystems including a rainforest, ocean, and mangrove wetland, designed to test self-sustaining habitats for humans.
Constructed in the late '80s and early '90s, Biosphere 2 initially housed eight 'Biospherians' who attempted to create a closed ecosystem, facing challenges like oxygen depletion.
The facility symbolizes innovative research in ecology, though initial missions faced problems that shifted focus from human habitation to broader ecological studies under Columbia University's management.
Biosphere 2, now a living laboratory, uses advanced technology to research ecological processes, ultimately aiming to inform real-world environmental sustainability efforts.
