Oceans Are In Trouble: Plastic & Warming
Oceans cover 71% of Earth and: - Produce 50% of oxygen we breathe - Absorb 25% of CO₂ we emit - Feed 3 billion people - Regulate climate (currents move heat) - Home to 80% of life on Earth
Future Champions (Ages 11-14) | Climate & Environment
In 2050, when you're 38, will oceans be alive or dead? Depends on next 10 years.
OCEANS = LIFE SUPPORT SYSTEM
Oceans cover 71% of Earth and:
- Produce 50% of oxygen we breathe
- Absorb 25% of CO₂ we emit
- Feed 3 billion people
- Regulate climate (currents move heat)
- Home to 80% of life on Earth
Without healthy oceans, humans can't survive
PROBLEM 1: PLASTIC POLLUTION
8 million tons of plastic enter oceans annually
That's 1 garbage truck per minute!
By 2050: More plastic than fish (by weight)
Where it comes from:
- Single-use bottles, bags, straws (40%)
- Fishing gear (20%)
- Packaging (20%)
- Microplastics (20%)
What it does:
- Fish eat it (then we eat the fish!)
- Turtles choke on bags
- Birds feed plastic to babies
- Breaks into microplastics (never disappears)
- Enters food chain (found in human blood!)
PROBLEM 2: OCEAN WARMING
Oceans absorb 90% of extra heat from climate change
Effects:
- Coral bleaching (50% of reefs dead)
- Fish moving to cooler waters (fisheries collapse)
- Stronger hurricanes (warm water = fuel)
- Sea ice melting (Arctic animals dying)
In YOUR 2050:
- Most coral reefs gone
- Fish populations crashed
- Coastal cities flooding Unless we act NOW
PROBLEM 3: OCEAN ACIDIFICATION
Ocean absorbs CO₂ → becomes carbonic acid → pH drops
Ocean pH:
- Pre-industrial: 8.2
- Now: 8.1 (30% more acidic!)
- 2050 path: 7.9 (70% more acidic)
Effects:
- Shellfish can't build shells
- Coral skeletons dissolve
- Food web collapses
SOLUTIONS YOU CAN DO
1. STOP PLASTIC:
- Reusable bottles, bags, straws
- Refuse single-use everything
- Pressure companies to stop plastic packaging
2. REDUCE EMISSIONS:
- Oceans warm because of CO₂
- All climate action = ocean action
3. EAT SUSTAINABLE SEAFOOD:
- Check seafoodwatch.org
- Avoid overfished species
- Choose ocean-friendly options
4. BEACH CLEANUPS:
- Every piece removed = one less piece in ocean
ACTIVITY 1: PLASTIC AUDIT
Track ALL plastic you use for 1 week:
- Bottles: ___
- Bags: ___
- Food packaging: ___
- Other: ___ Total: ___
Then: Find reusable alternatives for each!
ACTIVITY 2: OCEAN ACIDIFICATION EXPERIMENT
Materials: Seashell, vinegar, jar
Put shell in vinegar (acid). Wait 24 hours. Shell dissolves!
This is what happens to ocean life as oceans acidify.
ACTIVITY 3: BEACH/STREAM CLEANUP
Organize cleanup:
- Collect trash from beach or stream
- Sort by type
- Weigh it
- Post results: "We removed ___ lbs of ocean-bound trash!"
