What you need is OXYGEN - Just get it by a superlative donor ---> MOSS

THE REASON THAT MOSS PRODUCES MUCH MORE OXYGEN IN THE AIR THAN THE LEAFS FROM TREES AND BUSHES IS: Moss is a non-vascular plant, meaning that it has no internal system to transport water. Instead, it grows by spreading out as ground cover reaching most of all less than 2 inches Photosynthesis is the process by which plants make and store their food. With the help of a green substance called chlorophyll. Sunlight is combined with carbon dioxide and water and converted to sugar and starch. The process releases oxygen as an end product. Rather than true leaves, mosses have microphylls. These are leaf-like structures with an unbranched vein evolved from tiny bits of tissue found on the stems of leafless and more primitive plant forms. The GAMETOPHYTE is the dominant phase in the life cycle of moss plants. This is the form of the plant that most people are familiar with since it is often seen carpeting trees, rocks, and parts of the forest floor. In contradiction the photosynthesis of moss takes place in the so called gametophyte phase. The GAMETOPHYTE phase is superlative to the classical photosynthesis for creating OXYGEN. THIS IS THE REASON WHY ONE SQUARE METER MOSS BRINGS THE SAME QUANTITY OF OXYGEN IN THE AIR THAN 40 TREES
