Since we humans started creating our nests indoors, plants have been important companions. Being close to plants is important in many ways. Plants serve the function of filling the air with oxygen* so that oxygen dependent life can thrive on Earth. Plants indoors increase the oxygen content of air, clean toxic chemicals from it and buffer the humidity. It is especially important to have plants where many electric devices are up and running, for instance in the office.

*By photosynthesis of green plants, carbon dioxide (CO2) from the atmosphere is used in order to form carbohydrates or sugars. At the same time one water molecule (H20) is split in the cells in order to sustain photosynthesis and oxygen (O2) is released. It is believed that the Earth was devoid of oxygen 3.5 million years ago, but since then oxygen has formed gradually during photosynthesis. At the present moment oxygen content of the atmosphere is around 21%.
