Aluminum is a fascinating metal: light, stainless and easy to process. One hundred years ago, it was still so exotic that it was presented at world expositions. The metal has become an essential part of our daily lives. We drink from aluminum cans, use aluminum-containing deodorants and sunscreens and it increases the effectiveness of vaccines. But, currently, critical voices are being heard about this metal. Large amounts of resources and energy are needed for the production of aluminum. The extraction can lead to environmental disasters of considerable dimension, as happened in Hungary almost one year ago. Furthermore, scientists suspect that the toxic effect of aluminum could be having an influence on diseases such as Alzheimer’s and allergies. Directed by Bert Ehgartner. Produced by Kurt Langbein.
