Scouts learn about ecology, pollution, endangered species, pollination by bees, and other environmental topics while working on the Environmental Science merit badge. They also study how parts of the ecosystem interact through repeated observation.
Either Sustainability merit badge or Environmental Science merit badge is required for the rank of Eagle.

What Is an Ecosystem?
An ecosystem is a region where plants, animals, and other organisms, as well as weather and terrain, work together to support life. Each factor in an ecosystem depends on the other factors. If one of the factors changes, all of the others must adapt, migrate, or die. Read more about ecosystems and see some examples.
What Is Acid Rain?
Acid rain is rain, snow, fog, hail, or mist which has acidic components, such as sulfuric acid or nitric acid. These components come from air pollution and can be caused by the burning of fossil fuels. Acid rain can harm ecosystems, damage buildings, and negatively impact human health. Read more about the effects of acid rain and see some examples.
Impact of a Waterborne Pollutant on an Aquatic Community
When pollutants are dumped into rivers and oceans this harms animals and decreases their population. Sewage can cause disease. Trash can harm animals when they swallow it or get tangled in it. Chemical pollutants are swallowed and make the animals sick. Organic pollutants can cause algae to increase which uses more of the oxygen in the water, making the water unsuitable for some animals. Smaller animals may be especially susceptible. But this still harms larger animals because they depend on these smaller creatures for food. As populations decrease or are wiped out entirely, the entire ecosystem can be permanently damaged by any of these types of water pollution.
Examples of Soil Erosion
- River Banks
- Cracks in Rocks
- Gravitational Erosion
- Coastal Erosion
See examples of twelve endangered species which have recovered. Pick one you are interested in an learn more. See the list.
The USDA has a site which will help you find out what invasive species are a problem in your area. You can search by region or state.

Requirement 4 Helps and Answers
Study Area Tips
- Take notes, make drawings, and take pictures so you can remember all of the diversity you observed.
- Not all of the grass you see is “grass”. There might be many different types.
- Check with a local nature center to see if they have any checklists of plants and wildlife common in your area. This will help with noticing different things.

Requirement 5 Helps and Answers
What Is an Environmental Impact Statement?
An environmental impact statement (EIS) is a document which describes the impact of a proposed project on the environment. For example, you might consider if a project will displace or harm wildlife in the area.
