1991 年，美国在亚利桑那州图森市以北沙漠中建成了一座微型人工生态循环系统，名为“生物圈 2 号”。由于把地球本身称作“生物圈 1 号”，因此得名“生物圈 2 号”。该实验室由前橄榄球运动员约翰•艾伦发起，并与几家财团联手出资，委托空间生物圈风险投资公司承建，历时 8 年，耗资 1.5 亿美元。
生物圈 2 号实验室是一个封闭的生态系统，旨在探索人类在未来的生存环境。该实验室由一系列相互连接的建筑组成，包括能源、农业、水资源、氧气和排水系统。实验室内还有多种动物和植物，以及一个大型地下森林，为各种生物提供栖息地。
通过生物圈 2 号实验室，科学家们试图模拟地球上的生态系统，以了解人类在未来的生存环境。该实验室提供了一个独特的环境，以研究生态循环、环境变化和人类行为对未来的影响。

news content:
On November 25, 1991, the United States completed the construction of a micro-artificial ecosystem called the Biosphere 2 Lab in the desert of Payson, Arizona. The lab, located in the north of Payson, was built by former NFL player John 艾伦 and several wealthy corporations, with a joint investment of $150 million and was constructed by Space Biosphere Risk Investment Company. The construction of the lab took eight years and cost $150 million.
The Biosphere 2 Lab is an artificial ecosystem designed to explore the future environment for humans. The lab consists of a series of interconnected buildings, including energy, agriculture, water, oxygen, and waste management systems. The lab also has various animals and plants, as well as a large underground forest, providing habitats for various species.
Through the Biosphere 2 Lab, scientists attempt to simulate the Earth’s ecosystem in order to understand the impact of human behavior on the environment in the future. The lab offers a unique environment to study ecological cycles, environmental changes, and the impact of human behavior on the future.
