It is this convincing hard data that other environmental advocates lack. Grassroots groups are a good example. Some community-organized groups, like the one led by Lois Gibbs in Love Canal, have been successful in making the government and industry respond to their specific needs. The most successful groups have been the ones that gathered the scientific reports and raised money for more research. With thousands of small groups seeking attention across the country, it is those which have evidence to support their arguments that are winning the attention of politicians and forcing industry to take action.
Science can lend credibility to their struggles and the environmental movement as a whole.
Grassroot movements supported by science are effective within the local environment, but they can also be sabotaged by industry. Industry has the money and power to sue these groups, and these groups often do not have the resources to fight back. Additionally, industry also uses grassroots tactic in organizing its own anti-environmental legislation lobby groups. With thousands of grassroots groups in existence, separating the good from the bad can be a formidable task. These impostor grassroots groups are an example of industrial greenwashing by which an industry that is actually harming the environment conceals its true motives.
