Kind cares about the environment, this we know. They target people that also care about the environment. They also care about being healthy and being good for the community. Something that would encompass all three of these things would be having biodegradable wrappers.
Biodegradable products are safer for the environment because they break down naturally and just become mainly fertilizer for whatever piece of Earth they end up in. This is also healthier because biodegradable products contain little to no harsh chemicals.
