Our lungs..we don't give them credit for the work they do. They are the reason we live, their gas exchange is what keeps us alive except due to our polluted environment we put them to work. So many pollutants in our air, so many doors open for developing cancer we must get our heads together and find an alternative to transportation and energy efficiency. #energyefficiency #gogreen #makechanges #environmentalconciousness #lungs #gasexchange
