This document discusses different types of air and water pollution. It describes air pollution as the contamination of the air from toxic gases from smoke, fog, and greenhouse gases. Water pollution comes from sources like acid rain, industrial discharges, and farm runoff. One significant area of water pollution is the Great Pacific Garbage Patch, which is a large area of accumulated trash between the US and Japan caused by ocean currents carrying waste from North America and Asia. The trash patch endangers marine life through ingestion, entanglement, and spreading of toxic chemicals as plastics break down. Reducing pollution requires efforts like recycling, educating others, and cleaning beaches and shores.

1. Waste And
Pollution

2. Air Pollution

3. What is it?
• Contamination of the Air and Atmosphere
• Produce by toxic gases
• Smoke and fog

4. Types
• Industrial Air pollution
• Greenhouse effect:
- Main polutant that is warming the
air
• Most common Smog:
- Mixture of smoke and fog
-Given by factories

5. Prevention
• Ride bikes
• Carpool
• By natural things
• Use Natural Resources

6. Main polutants
• Factories
- Huge tubes
• Cars
• Trucks

7. Water Pollution

8. Types of Water Pollution
• acid rain
• industrial discharges
• CO2 falling from the atmosphere
• Farm chemical discharges

9. Sedimentation
• garbage & materials -> break down
• foggy
• Bottom of the sea/ocean

10. Sedimentation
• No sunlight -> no fish food
• Blurry / Toxic

11. Sedimentation
• huge filters
• robots

12. Great Pacific Garbage Patch

13. What is It?
•Like a ‘trash island’
•Trash accumulating in Great Pacific Garbage Patch
•Miles

14. Where
and Why?
• Between United States and
Japan
• The trash mostly comes
from US and Japan but
Mexico, Canada, and Russia
are also giving it out
•The trash comes here
because of air currents

15. Ingestion
• When plastic sinks, animals think its food and start eating it, if
they are able to digest it, they still die of intoxication.

16. Entanglement
• Called Ghost Fishing
• The majority of the fishing nets left behind, later, fishes are
caught in them
•Nets cause them to drown till death
•Stay like this until bodies succumb

17. Photodegradation
•The heat of the sun melts down the plastic, making the toxics
of it spread out through the water. These toxics then intoxicate
marine debris and animals.
•Bisphenol A is one of the toxics
•Years it takes to
photodegradate
the substances.

18. What Can We Do?
•Recycle
•Clean up beaches and shores
•Educate others
•Reuse
