Human Impact
📋 What it is
Human actions — pollution, deforestation, overfishing — can disrupt ecosystems, sometimes fast.
🗣️ Coach says
Humans are part of ecosystems, and our actions ripple hard. Cutting forests removes habitat; pollution poisons food webs; overfishing empties oceans. The good news: because everything is connected, careful choices can help ecosystems recover too. Impact runs both ways.

Human actions ripple through ecosystems — and careful choices can help them recover.

What's a tree's favorite kind of music?
Root-and-roll!
😲 Whoa!
The ozone layer, once thinning dangerously from human-made chemicals, is now HEALING because the world agreed to ban them — proof that impact can be reversed.
✅ Quick check: Cutting down a forest removes trees. Name one OTHER effect on the ecosystem.
Say your answer out loud first — then reveal.
Many — animals lose habitat, soil erodes, less CO₂ is absorbed, and local rainfall can drop; effects ripple widely.
Deforestation cascades through the connected ecosystem beyond just fewer trees.
