Pollution is affecting this diversity as well as human health, the economy, social justice, and national security. As scientists hold the key to this wealth of information, we need to act upon it in an ethical manner, communicate it to the public so that they can do the same, and search for practical solutions. Scientists can respond to the challenges of preserving and restoring the environment like no other group can. Scientists have the knowledge to interpret the facts. 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.
