Trace the life cycle of three different plastic bottles from beginning to end.
Students sketch the life cycle of a plastic bottle from manufacturing to disposal and discuss in groups. Uncover what effect plastic has on the environment and what we should think about when buying or throwing it away.
Plastic is made from oil and gas (natural resources that are extracted from the ground). Many plastics that are used to make every day products can be recycled, such as Polyethylene Terephthalate (PET) which is used to create water, juice and pop bottles. This type of plastic can be recycled and used to make new products.
The use of plastic products can harm wildlife and enter the food chain. The Great Pacific Garbage Patch and others contain large amounts of garbage and plastic that aren’t biodegradable. Smaller marine animals contain pieces of plastic that have broken down into tiny pieces because they mistake it for food.
When fish eat plastic, it enters the food chain because larger fish eat the smaller fish (containing plastic) and we humans eat the larger fish, like tuna.
Recycling is an important way to reduce the amount of plastic that ends up in landfill sites and the ocean. Reducing our use of plastic and switching to reusable products such as refillable water bottles also reduces the amount of plastic in the environment.
How can our future needs for clean energy be met while also respecting the perspectives of various stakeholders?
