Central Colorado Tree Service

You probably already know that trees produce oxygen in the atmosphere and absorb dangerous substances like carbon dioxide. About how much carbon dioxide can a single tree absorb in a year? If you guessed 40 pounds, you're right. Over a half century, that tree would filter a ton of carbon dioxide from the atmosphere.

According to the Guinness Book of Records, the largest tree to be transplanted was an oak tree, aged 180–220 years and measuring 17.67 m (58 ft) tall, 31.6 m (104 ft) wide and weighing approximately 415.5 tonnes. "Old Glory" was moved 0.25 miles to a new park in LA on January 20th 2004.
