caught in the plastic and get hurt
4% of crude oil goes to making plastic
Advantages to using plastic

The cars weigh get less and that decreases the amount of gasoline, which is good
The foodindustry can keep the food more safe with plastic and the food will not get bad

Enviromental problems with aluminium
Aluminium :
Environmental problems
• It takes a lot of energy to create aluminium from bauxit
• It takes 200 – 500 years to break down Aluminum naturally
• Animals can accidentally eat and cut themselves on the aluminum
REUSE and RECYCLE Where we found bauxit in the world
Bauxit transports to Iceland to get melt into aluminium. Then the metal will be exported to for example Sweden
•It’s an easy metal to transport, so it doesn’t require that much fuel! •A part of aluminum can be recycled an infinite amount of times •If you recycle aluminum, you only use 5% of the energy to create new aluminum
Aluminium : Environmental problems
Products of aluminium Examples what it’s
used for: Tealights, Lamps, cans etc
The Aluminum in the bedrock is liberated when there’s acid rain. When it gets down in the lakes the fish and the plants are injured. Aluminum disturbs root growth and the function in the root.
