Topics discussed include burning of fossil fuels and change in Earth's climate leading to growth of didymo, growth of long stalks of didymo in search of phosphorus and views of ecologist Brad Taylor from Dartmouth College in Hanover, New Hampshire on spread of didymo. Issues regarding consumption of phosphorus by terrestrial plants leading to its depletion from rivers leading to algal blooms is presented."

"Award-winning artist and professor Sam Van Aken has managed to accomplish what very few people are able to do - combine art and science together in a project that is as visually stunning, as it is biologically amazing. He has created trees that grow not one or two, but more than 40 types of stone fruit that include numerous kinds of peaches, plums, apricots, nectarines and cherries. What's even more amazing is that many of the fruits are ancient, hard-to-find, varieties."
