Final answer:
Eco-packaging does not primarily address air pollution. It's more focused on reducing water and land pollution and promoting recycling. Economic policies must balance the benefits of environmental protection with their economic costs.
Step-by-step explanation:
Eco-packaging must address various environmental issues but does not directly address air pollution. Among the list provided, air pollution is the exception because eco-packaging is more directly related to water pollution, land pollution, and recycling. These aspects are crucial for reducing the environmental impact of packaging materials.
From an economic perspective, aiming for zero pollution might not always be practical or cost-effective, as the resources needed to eliminate the last increments of pollution often outweigh the benefits. However, incorporating environmental policies like recycling can significantly reduce contamination from plastics, glass, and other materials. Making recycling mandatory could be a sound policy since it is a relatively low-cost method of mitigating environmental damage and conserving resources.
When considering environmental regulations, such as those pertaining to the hypothetical 'gunk' in the Land of Purity, it's essential to evaluate the trade-off between economic output and environmental protection. This consideration ensures that while striving for a clean environment, the economic cost of regulations does not unnecessarily hinder growth.
