Whether we're discussing how to make our roads safer or the environmental benefits of getting more people to commute by bike, cycling is a topic that many of us feel passionately about. Cycling is an integral and increasingly important part of London's transport network, but there is still a long way to go before it becomes as inclusive, safe and widely enjoyed here as it is in the likes of Copenhagen and Amsterdam.
For us, the wives of black cab drivers in London, this year Valentine's Day has a whole other meaning. In our fight to save our partners' jobs and livelihoods, we are simply asking our partners (and all the cab drivers and people working in the black cab industry) to leave us a message from the heart and make a pledge towards the "Action for Cabbies".
I just couldn't sit by and watch the slow and painful death of the iconic black cab industry; I had to take action. After all, this is an industry that not only supports me and my family but also the families of 25,000 black cabbies in London, and related businesses such as garages and vehicle manufacturers.
Every year I rashly agree to forecast/guess what will be the key sustainability trends for the year ahead. This time last year I did predict that under investment in flood defences would force government onto the back foot reducing them to sticky plaster solutions - so I got at least one right! What then might happen in 2016?
