资源简介：
An improved advertising system can include a location having a substantially large expanse of living greenery， a predetermined design for an advertisement， and a chlorophyll-based agent. The location can be observable by viewers at a predefined minimum viewing distance. The chlorophyll-based agent can be used to paint the predetermined design on the living greenery. The chlorophyll-based agent can be non-detrimental to the health of the living greenery. The predetermined design painted on the living greenery with the chlorophyll-based agent can be only viewable by viewers at the predefined minimum viewing distance. Living greenery treated with the chlorophyll-based agent can be visibly distinguishable from and shinier than neighboring untreated living greenery. When a viewer is nearer than the minimum predefined viewing distance， a difference in shine and color between the treated living greenery and the untreated living greenery can be substantially unnoticeable.
