Leaves and growing fresh grass are green because they contain a natural pigment known as chlorophyll. Chlorophyll takes the energy of sunlight and uses it to convert carbon dioxide and water into chemical energy, in the form of glucose, or natural sugar, which allows the plant to grow. This process is called photosynthesis. Chlorophyll absorbs the long wavelengths (red) and short wavelengths (blue) of the light, but the green light is reflected, making the grass and leaves appear green. 

Chlorophyll does not absorb green light because it first arose in organisms living in oceans where purple halo bacteria were already exploiting photosynthesis. 

Their purple color arose because they extracted energy in the green portion of the spectrum using bacteriorho dosing. The new organisms that then later came to dominate the extraction of light were selected to exploit those portions of the spectrum not used by the halo bacteria. 

Green is the color most commonly associated in Europe and the U.S. with nature, vivacity and life it is the color of many environmental organizations, such as Greenpeace, and of the Green Parties in Europe. 

Many cities have designated a garden or park as a green space, and use green trash bins and containers. A green cross is commonly used to designate pharmacies in Europe.

In China, green is associated with the east, with sunrise, and with life and growth. In Thailand, the color green is consider auspicious for those born on a Wednesday day (light green for those born at night).
