What government agency enforces each of the major environmental laws
Read the example of Edward Jenners discovery of the immunization against smallpox:
A British physician named Edward Jenner noticed that dairymaids living in his hometown often contracted cowpox, a nonlethal disease instead of smallpox. Dr. Jenner suspected the exposure to cowpox was somehow granting protection against smallpox. He decided to test this by intentionally infecting a young boy with cowpox, then exposing him to smallpox. Despite 20 inoculations, the boy never came down with smallpox. Meanwhile, other children living nearby that had not been exposed to cowpox were becoming infected with smallpox. Dr. Jenner reported to the Royal Society of Medicine that exposure to cowpox had successfully granted immunity against smallpox.How do scientists forecast volcano eruptions?
Scientists’ main way of forecasting a volcanic eruption is thru seismographic detection. Almost always before an eruption, there is some sort of earth tremor. This earth tremor is what helps scientists forecast eruptions. Are there more ways that can help predict eruptions sooner?
