International Compost Awareness Week 2018

I chose to take part in this poster contest because I believe good soil is necessary for a balanced nutrition. By digging underground tunnels the earthworm turns waste into soil and creates drainage for plants. Its excretions are the best fertilizer you could wish for. The poster is supposed to put a spotlight on these little genii as they are working unseen below ground most of the time.
