The Silent Spring Institute is a group of very smart people who want to make sure that we all stay safe and healthy. They study chemicals that are really tiny and can be in things like our water, air, and even the dust in our homes.
These tiny chemicals are called "toxins" and they can be really bad for our bodies if we are exposed to too much of them. The Silent Spring Institute uses science to figure out where these toxins are coming from and how we can stop them from hurting us.
They also work to help people who are already sick from these toxins and try to prevent other people from getting sick. They are kind of like superheroes, but instead of fighting bad guys, they fight tiny chemicals that can make us sick.
