Milan’s International Festival of Lights, or Festival Internazionale Della Luce in Italian, is a month-long festival in Milan designed to transform the city into an open-air stage of contemporary art. The rules of the festival are simple; artists must use energy efficient LED lights in order to illuminate city squares, avenues, historical parks, monuments, and buildings for the 2010 Christmas season. Contestants have been submitting art proposals all year and finalists will have the opportunity to install their work for all to see right in the heart of Milan.
Many variables must be taken into account when determining the environmental impacts of natural and artificial trees. Natural trees remove CO2 from the atmosphere while growing, but often stress the environment with fertilizer, pesticide, irrigation, and soil depletion. Artificial trees are typically shipped a much greater distance (e.g. from China), and require significantly more natural resources, but can be reused for many years. How a tree is grown or manufactured, the distance it is shipped, the lifespan, and method of disposal, are all important factors when evaluating the pros and cons of each tree type.
