The film and television industry is integral to the economics and culture of the Southern California region. It is also a major contributing factor to the environmental problems in the region. Currently the Motion Picture, Television, and Commercial Industries Act of 1984 is the only regulation written specifically for the entertainment industry. This regulation was created with the purpose of streamlining the film permitting process to prevent run-away production, taking production out of state, and encourage growth. A change in this regulation is needed since studios routinely fail to meet environmental standards or work towards improvement during on-location filming. Amendments to this regulation requiring permits to contain environmental conditions would improve environmental conditions and stay true to the original purpose of the act.

Trash and car/truck bodies in the San Benito River and along its banks continue to present a challenge as state mandated basin plans often fail to address these pollutants. To measure the extent of the problem, an assessment of trash and car/truck bodies was completed along four locations of the river. The survey results indicated a need for a Cleanup Management Plan that should include a streamlining process for the removal of car/truck bodies, as well as guidelines for river cleanups. Existing cleanup plans and internet resources were analyzed for creation of the Cleanup Management Plan for the San Benito River.

El presente estudio describe la comunidad de macroalgas epizóicas de Pinctada mazatlanica y la compara con la del substrato rocoso. Colectamos un total de 36 muestras de la comunidad de macroalgas, 18 muestras sobre ostras y otras tantas sobre substrato rocoso en la Península San Juan Nepomuceno, bahía de La Paz, México. Las algas fueron colectadas mediante buceo SCUBA raspando las distintas superficies (25 cm2 de substrato rocoso). El tamaño de muestra fue ajustado por curva de acumulación de especies y expresado con un modelo polinomial. Comparamos las comunidades de algas con análisis multivariantes de similitud basados en el índice de Bray-Curtis, entre substratos, diferentes alturas de ostras perleras y profundidades. Encontramos 27 especies de algas epizóicas (15.4% Clorophyta, 3.8% Phaeophyta y 80.8% Rhodophyta) con una disimilitud de 71.16% con respecto al substrato rocoso. El dendrograma mostró tres agrupaciones de macroalgas en P. mazatlanica. El primero caracterizado por Chondria, Jania, Herposiphonia tenella y Gracilaria. El segundo compuesto por Jania, Polysiphonia acuminata, P. decusata y Spyridia filamentosa. El tercero constituido por Polysiphonia sp., Jania, Herposiphonia tenella, Ceramium canouii y Amphiroa sp. Estas agrupaciones y los talos filamentosos de las algas epizóicas corresponden a estados iniciales de sucesión.
