Celebrities can influence the public to help environmental issues through their actions. Julia Louis-Dreyfus and her husband have supported environmental organizations and made their home green. Leonardo DiCaprio produced the documentary "The 11th Hour" to educate about climate change. While most Americans commute by car, buying a hybrid is better for the environment and many celebrities own hybrids. Small individual actions like recycling, composting, and conserving water can collectively make a positive impact.
