Protecting Our Oceans by Jeanette Leardi
Introduction• Oil pours out and forms a
thick blanket on the water.• The spill has polluted clean
water and cause huge changes.
• About two thirds of earth is covered by ocean water.
Debris
• Carelessly tossed litter and trash end up in the ocean sooner or later.
• Debris is pollution that’s easy to see.
• Different kind’s of debris take different amount’s or time to break down
Toxic Waste • Toxic waste examples can
be chemicals, fertilizer • Once toxic waste gets into
the ground rain washes it deep into the earths ground.
• Toxic can kill off fish, wildlife and plants
Sewage• Sewage is anything we flush
down our toilet or down drains and sewers.
• The travel to a treatment center and take out bacteria
• The bacteria can harm and even kill living things.
Oil spills and leaks • Large oil spills greatly harm
both the water and the coastline.
• Spills happen when companies drill for oil off shore.
• Spills can also happen when tankers hit something or run aground in shallow waters.
Acid Rain
• Cause: When cars, trucks, power plant, and -factories burn fuel.
• Effect: The gases combine with air and form strong acid.
Chapter 2: How does pollution affect marine life?
• All living things in the ocean are connected In a cycle of life and death.
• Plants and animals that live in or by the oceans is an important member od the ecosystem
• If pollution harms any plants or animals species affect others in the ecosystem
Pollution and fish • An oil spill can keep fish
from breathing and poison the plants food.
• Fish also be harmed by debris.
• Alage would grow to fast arid use all the oxegen the fish need to breathe
Pollution and Sea birds • oil spills harm sea birds.• It coats there feathers with
oil then they cant fly.• Birds can die from eating
the trash on the beach
Pollution and ocean animals • Current carry toxic waste far
and wide.• Whales and dolphins can die
from pollution.• The pollution in water can
effect a lot of things.
How deep is really deep?• Part of the ocean floors are
more than 8 miles deep.• We could not explore the
ocean about 56 years ago.• Cause Scientists use
submersible.• Effect we can see what
happens in the ocean.
Chapter 3 : What’s being done to stop ocean pollution ?
• People gather all over there states, river ,lakes and beaches to pick up trash.
• Countries have set international safety rules.
• The united nations created a special program that supports countries as they make their water quality better.
Conclusion • Ocean life is linked to
through ecosysteams, food chain and ocean currents.
• Oil spills can cause illness and death to ocean life
• Nations can help protect all the oceans.
