In New York City, 3.3 million people planting one tree per day would succeed in planting 1 billion trees in less than a year.

Since automobiles take up so much space in this town transportation would have to convert to small vehicle transit having an environmental footprint less than 1% of cars and other considerable benefits typical of bicycles including safety, distributed on-demand mobility, low-cost, no emissions; increases in efficiency, speed and range three to four times (300% to 400%) that of walking.

pls advise your theotrical computation of naturally occurring co2 emissions during late ice age and volcanic period about 1500 bc. Also co2/ methane emission in Kenya due to fissures in earth, late volcanoes skew accurate measurement
