Most Important Organism? Marine plants produce between 70 and 80 percent of the oxygen in the atmosphere.
Trees clean the air. Trees absorb odors and pollutant gases (nitrogen oxides, ammonia, sulfur dioxide and ozone) and filter particulates out of the air by trapping them on their leaves and bark. Trees provide oxygen. In one year an acre of mature trees can provide enough oxygen for 18 people. Trees cool the streets and the city. Average temperatures in Los Angeles have risen 6Â°F in the last 50 years as tree coverage has declined and the number of heat-absorbing roads and buildings has increased.
