Wiki Loves Earth

Wiki Loves Earth is the biggest international photo contest devoted to nature heritage, and it has been held by Wikimedia Ukraine since 2013. The goal of the competition is to collect and publish under the CC-BY-SA 4.0 license pictures of Natural Heritage sites in order to illustrate articles on Wikipedia and other Wikiprojects. The idea is the same as the Wiki Loves Monuments contest, but natural monuments are the main concern here.
