What would you think if I mentioned helmets? For years, the best-known helmets were glass containers in which beer or soft drinks were placed. These were bottles similar to the current ones, but were never thrown away. There was no need for any regulation to prevent this. After the drinks were consumed, the helmets were taken back to the shops or bars where they were purchased. In return, you got them to discount their price. The concept was the most sustainable. I pay for the content but not the container. On the other hand, savings when returning them are also counted. It was an excellent marketing campaign. Gained customer loyalty without having to invest in advertising. Anyone give more?

However, there was a far more important force that transcended all of the above to do so. It was about values. The value of not polluting the street, the value of not throwing away what can be reused regardless of the economic possibilities each has, and ultimately the value of being civic.

The most obvious proof of this is what happened when you went to buy bread at that time. In that or any other job, no one needed to remind you to carry the bag with you when you went to pick it up, or threaten to charge you any fees for doing so. For example, in the bakeries, you could see the collection of bags or sacks that were hung on different hooks, mostly hand-knitted, left by the owners in the morning, and that they had already collected hours later with the bread inside. . Recycling and the fight against plastic are in the same action.

These are just a few of the day-to-day cases that occurred at that time and are ultimately part of the childhood of many of us.

So remember, my grandparents, like yours, have unknowingly dedicated their entire lives to protecting biodiversity. They were the first environmentalists to actually exist, not us, with their simple but logical actions.
