Human race has always been fascinated by the idea of living on moon and other planets. However, the most crucial hurdle in such plans is the absence of oxygen on these planets and that has led to some amazing inventions.
Julian Melchiorri is a scientist and artist who has unveiled a synthetic leaf that can quite possibly transform the whole idea of space exploration.

The breathing lead has been created from chloroplasts (responsible for photosynthesis) and is suspended in a body that has been made from silk protein.

The leaf will absorb CO2 and produce oxygen and organic compounds as long as water and visible light are available.

These leaves consume low energy, weight very less and are completely biological, thus imparting minimal impact to space flights (or your living room for that matter).
