Flying was once the preserve of the rich and leisured, now most of us can afford to fly - and are doing so in increasing numbers. However, this love affair with flying comes at a cost. Should I Really Give Up Flying? takes a new look at air tourism and its impact on the environment, from the beautiful city of Venice, vulnerable to rising sea levels, to prolonged drought and soaring temperatures in Spain. The programme also takes a look at the very latest in aviation and fuel advances designed to make taking to the skies more eco-friendly.
