MEXICO CITY -- Lewis Hamilton has brushed off criticism of his recent attempts to raise awareness about climate change and is planning to live a carbon-neutral lifestyle by the end of the year.
In the days following the Japanese Grand Prix, Hamilton posted a series of messages on Instagram in which he said he felt like "giving up on everything" because the "world is in such a mess".
The post attracted supportive comments from concerned fans as well as criticism from those pointing out the size of Hamilton's carbon footprint as a Formula One driver travelling the world and racing cars.
