There they help to reflect light beating down on them and slow what has become a tremendous pace of melt throughout the last several years. 'I just asked myself a very simple question: Is there a safe material that could help replace that lost reflectivity?' Found of Ice911, Leslie Field, told Mother Jones. What they landed...
