Explanation
★Source reduction covers reduced toxicity, less packaging and more durable products, so the answer is 1, 3 and 5.
★Source reduction, or waste prevention, cuts waste at its origin before it is made.
★Reducing toxicity lowers the hazard present in products and their waste.
★Less packaging directly reduces the material that becomes waste.
★More durable products last longer and are discarded less often.
★Composting and landfill handle waste after it is created, so they are not source reduction.
