The biodegradability of beads largely depends on their material composition. Natural materials like wood, clay, or certain plant-based polymers can be biodegradable, while synthetic beads made from plastics, such as polyethylene or polystyrene, are not biodegradable and can persist in the environment for hundreds of years. Additionally, biodegradable beads made from bioplastics exist, but their degradation can be influenced by environmental conditions. Always check the specific type of bead to determine its environmental impact.

Nuclear power plants produce about 0.0003 to 0.0005 metric tons of high-level radioactive waste per megawatt-hour (MWh) of electricity generated, translating to approximately 0.0003 to 0.0005 kilograms per kilowatt-hour (kWh). This waste primarily consists of spent nuclear fuel, which requires careful management and long-term storage due to its radioactivity. In comparison to fossil fuel plants, the amount of waste generated by nuclear power is significantly lower on a per-kWh basis.

Garbage is not inexhaustible; rather, it is a byproduct of human consumption and activity. While the volume of waste generated can be vast, it is finite and influenced by factors like population growth, consumption patterns, and recycling efforts. Effective waste management, recycling, and reducing consumption are essential to mitigate the impact of garbage on the environment. Ultimately, the sustainability of our waste practices determines how long we can manage the resources we consume.

Self-heating cans are often cheaper due to advancements in manufacturing technology that reduce production costs.
