Do you have plants in your office? 

A recent study by the University of Technology in Sydney shows that plants in your office can improve your bottom line by:  

Reducing indoor air pollution, reducing workplace illness, reducing sick-leave absences, reducing stress and negativity, removing unhealthy mould problems,
raising performance & productivity, improving job satisfaction, enhancing business image with potential clients and improving school performance
& patient well-being, contributing to at least 75% of Indoor Environmental Quality (IEQ) criteria.
