Snacking is something many like, but it is important that snacking does not harm the environment. If we try , snacking can even benefit the environment and counter certain issues.
The basics are something followed by many , but it's good to restate them. Use dustbins for disposing waste.
Now, for the other techniques. There are certain brands which use biodegradable packaging. Using these brands only if available is already a significant amount of plastic waste reduced, extremely small, yet significant .
This can be couples with food composting and increasing fruit intake. By doing so the environment benefits even more.
Wish you a sustainable snacking.
