The depletion of natural resources, ongoing energy crises and the dangers of global warming pose threats to our modern lifestyles.

With the Earth's population at more than 6.5 billion, the National Museum of Emerging Science and Innovation (known in Japanese as Miraikan) is currently hosting a special exhibition looking at how future generations can hope to survive.

Titled "6.5 billions' Survival -- Living with Emerging Sciences," the exhibition runs through Feb. 5. It presents an experience-based "survival-training program" exploring the frontiers of science as a human survival tool, considering the five themes of: energy, food, living environment, tools and communication.

The survival-training program is made up of three zones -- biological, living and modern -- and aims to deepen the understanding of visitors as to what constitutes the basic tools for human survival through graphic exhibits and interviews that the museum carried out with people of various ages and occupations to examine the different lifestyles of people today. Zone 2 examines the scientific and technological achievements necessary in order for the human species to survive in the future, with actual items, images and models of the innovations of tomorrow, such as a plant factory that cultivates plants with artificial light, and natural energy resources that do not emit carbon dioxide.

The exhibition runs through Feb. 5, 10 a.m.-5 p.m., at 1F Event Zone, Miraikan, 2-41 Aomi, Koto-ku, Tokyo. Admission is 900 yen for adults, 350 yen for children. For more info in English or Japanese, visit www.miraikan.jst.co.jp
