Given the task definition, example input & output, solve the new input case.
Generate an explanation for the given claim using the provided supporting material from the paragraph. Please consider the following points while generating an output. 1) The claim will always have supporting proof in the paragraph, and the paragraph will have a clear point of view supporting the claim. 2) There can be instances where direct correlation to the claim is not available. Make use of the sentences in the paragraph to provide a corresponding output supporting the claim. 3) The explanation should be at least one and at most twelve sentences long.
Example: Paragraph: "Although the story didn't cite the cost of appendectomy emergency or urgent surgery and we wish it had, we nonetheless will give it a satisfactory score because it at least cited what the editorial writer wrote, ""A secondary benefit is the savings to the hospital generated by minimizing staff and anesthesiologist presence late in the evening and during the wee hours of the morning."" As with our harms score above, although the story didn't give absolute numbers, in this case we think it was sufficient for it to report that ""The scientists found no significant difference among the groups in the patients' condition 30 days after surgery or in the length of their operation or hospital stay."" Although the story didn't give absolute numbers, in this case we think it was sufficient for it to report that ""The scientists found no significant difference among the groups in the patients' condition 30 days after surgery or in the length of their operation or hospital stay."" Despite running less than 300 words, this story did an adequate job in explaining the quality of the evidence, including pointing out limitations. No disease-mongering here. The story meets the bare minimum requirement for this criterion in that it at least cited what an editorial stated. The focus of the story was on a study comparing emergency appendectomy with surgery done up to 12 hours later or beyond. This is the whole focus of the story and one we applaud when it begins: ""Appendectomy is the most common emergency surgery in the world, but it doesn't have to be."" There were no claims made about the novelty of this research, and we may have wished for a bit more context on this. Nonetheless, the potential for guiding future care decisions was made clear. Not applicable. Given that the story only pulled excerpts from the journal article and the accompanying editorial, and didn't include any fresh quotes from interviews, we can't be sure of the extent to which it may have been influenced by a news release.". Claim: Some appendicitis cases may not require 'emergency' surgery
Output: We really don't understand why only a handful of mainstream news organizations reported this story. (At least in what we found.) The most common emergency surgery in the world. Rushing to emergency surgery may not carry any benefit. Waiting a few hours may be safer and less expensive. Why is that not a story? We applaud USA Today for finding time and space and clearly it didn't need to free up much space to do a good job telling the story. The story explains that as many as 300,0 appendectomies are done each year in the US. That figure alone explains why this is an important study to report.
The output is an analysis of the claim while considering the paragraph as a reference. The output highlights the key features presented in the paragraph and explains the claim accordingly.

New input case for you: Paragraph: "The annual effort to raise public awareness about the environment and inspire actions to clean it up marks its 41st anniversary on Friday, coinciding with the Christian Good Friday and Judaism's celebration of Passover. In an effort dubbed ""A Billion Acts of Green,"" organizers are encouraging people to observe Earth Day 2011 by pledging online at act.earthday.org/ to do something small but sustainable in their own lives to improve the planet's health -- from switching to compact fluorescent light bulbs to reducing the use of pesticides and other toxic chemicals. "Millions of people doing small, individual acts can add up to real change," said Chad Chitwood, a spokesman for the umbrella group coordinating efforts. There will be hundreds of rallies, workshops and other events around the United States, where Earth Day was born, and hundreds more overseas, where it is now celebrated in 192 countries. In the United States the activities range from the premiere of the new film from the director of "Who Killed the Electric Car?" (it's called "Revenge of the Electric Car") at the Tribeca Film Festival in New York to a discussion about creating a green economy in 12 cities along the Gulf Coast, where this time last year residents were reeling from the effects of the BP oil spill in the Gulf of Mexico. In the years since the first Earth Day was celebrated in 1970 the environmentalist movement made great strides with passage of the Clean Air Act, Clean Water Act, the Endangered Species Act and other groundbreaking laws. But the bipartisanship that marked the birth of Earth Day it was sponsored in Congress by a Wisconsin Democrat named Gaylord Nelson and a California Republican named Pete McCloskey is often missing in discussions about environmental policy today. Efforts to fight climate change by regulating greenhouse gases, for instance, face fierce resistance from many Republicans and members of the business community, who dispute the science supporting global warming and warn new rules to regulate emissions will kill jobs and raise energy costs." Claim: "Earth Day organizers call for ""a billion acts of green""."
Output:
If the environmental movement has a high holiday, Earth Day is it.
