“Seven new species of miniature frog, smaller than bumblebees, have been discovered clinging to survival on isolated mountaintops in Brazil. … The frogs, which are among the smallest land vertebrates, have evolved with fewer fingers and toes in order to reduce their size.” (http://www.theguardian.com/environment/2015/jun/04/seven-new-species-of-miniature-frogs-discovered-in-cloud-forests-of-brazil)
The frogs had hoped their reduced ‘footprint’ would escape the death knell of human notice.
“Human excrement is a bigger problem than the oxygen bottles, torn tents, broken ladders, and cans or wrappers teams left behind. … Human waste piling up over decades … posed a health hazard to people dependent on water from rivers fed by the region’s melting glaciers.” (http://uk.reuters.com/article/2015/03/04/us-nepal-everest-idUKKBN0M00A220150304)
A bigger problem than yellow snow.
