There are solutions. First of course, we should try to limit our consumption. For example, we can reduce our airplane travels. Any trip less than 1000 miles long should be done by train or car. Less flying doesn’t necessarily mean less vacation: one can travel less often but stay longer.
Second, we should offset carbon emissions in the air by planting trees. They absorb CO2 and produce oxygen. At the same time, offsetting should be seen as a helping factor not a justification for more emissions.
One tree absorbs on average 100 kg of CO2 in temperate regions over eight years when it is mature. For example, if the CO2 footprint of a person in a given year is 20 tons, by planting 200 trees that person’s carbon footprint will be offset in 8 years once the tree has grown which will take 10 to 20 years.
