      <p> It’s that awesome time of the year again where we at Soil for Life are hosting our yearly Eat for the Earth campaign. And we invite people and organizations all over the world to do the same and support the amazing work we are doing.  We are particularly excited this year because 2015 is the Year of the Soil and soil is our favourite thing!  We are so keen, in fact, that we have started this BLOG, that’s right a whole blog! Keep your eyes on this space for awesome tidbits and suggestions about how to build the soil, look after the earth and prepare healthy, delicious meals. </p>
