In 'Man Eating Trees,' Sokol employs humor to comment on man’s self-serving destruction of the environment. Sokol’s title could refer to trees that eat men or a man that eats trees. The artist used tar, a substance originally derived from pine trees, to render the man and trees echoing the environmentalist theme suggested by the title. The tar, which looks muddy where it is applied thickly and glowing where it is diluted with varnish, lends the work a dark, nightmarish quality.
