Environmental scientists are planet protectors who study air, water, soil, and living creatures to keep Earth healthy for everyone. They trek through forests, dive into coral reefs, and crunch computer data to discover how ecosystems work and what happens when they’re pushed off balance. Conservationists turn those discoveries into action—restoring wetlands, rescuing endangered species, or designing city parks that soak up stormwater and give wildlife a home. From analyzing tiny pollen grains to writing big policy reports, they prove that careful observation and passionate stewardship can safeguard the blue and green spaces we all share.
