Placing environment concerns above convenience

In the pursuit for a more comfortable life, humans rarely consider the damage to other living creatures and to the environment. This series questions today's values and lifestyles when measured against the resulting pollutants, waste and blight of natural resources. From an environmental perspective, we are taken on a journey spanning the ocean depths to deep forests and made to re-examine man's impact on nature. Suggestions on how to care for our planet and its finite resources are incorporated into each program, hopefully encouraging us to change our habits and way of life.
