In December 2009, Push embarked on his first long walk – his ‘Walk for Climate Justice’ – from Oxford, UK, to Copenhagen, Denmark, to raise awareness of the issues of climate change and poverty in advance of the UN conference on climate change in Copenhagen, COP15. In 2011, he repeated this effort in another Walk for Climate Justice in the southern Indian state of Karnataka, to call attention to the plight of small producers such as coffee growers in an era of climate change. This walk was supported by the Karnataka Growers Federation (KGF) and Centre for Social Markets (CSM), and reached 30,000 people directly, and through radio he was able to reach a million listeners a day!
