A 100-ft tree, 18 diameter at its base, produces 6,000 pounds of oxygen.. - Northwest Territories Forest Management. - Environment Canada, Canada's national environmental agency. On average, one tree produces nearly 260 pounds of oxygen each year.
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.
