Final answer:
The largest contributor to pandemic waste includes pharmaceutical companies, healthcare facilities, individuals, and government agencies.
Step-by-step explanation:
The largest contributor to the pandemic waste varies depending on different factors. While pharmaceutical companies contribute to waste through the production and packaging of medications and vaccines, healthcare facilities also generate waste through medical supplies, personal protective equipment, and disposable items. However, individuals are also significant contributors to pandemic waste through the increased use of single-use items like masks, gloves, and sanitizing wipes. Government agencies, such as health and social services departments, are responsible for waste management and implementing policies to reduce waste.
