Squares of Climate Concern

The square (with as many lines as syllables per line) is a poetry-form that has existed  for centuries and is now enjoying a revival.  Here are three small squares that come from my concerns for the precarious imbalances we humans have created within our natural environment. 

      There is no                           
      place to throw                     
      that's away.                          

                    If icebergs melt,
                    what metaphor
                    to use for the
                    hidden problem?

                                        Conquests of
                                        nature are
                                        mistaken.
