Scientists have addressed the idea, in "A life of its own" by Michael Specter, of using synthetic biology to mend environmental issues. Synthetic biology combines  the "elements of engineering, chemistry, computer science, and molecular biology…to assemble the biological tools necessary to redesign the living world" (Specter 364). There are both positive and negative impacts of a synthetic world on the environment movement

    & Walter, 1998) Osmosis plays a crucial part in both chemistry and biology and it is therefore essential to differentiate between the two different concepts. In biology osmosis is generally defined as the movement of water, via diffusion, through a semi-permeable membrane. The water diffuses from a hypotonic solution (low concentration of solute) to a hypertonic solution.(High concentration of solute).
