What does "one less pull tab, more environmental protection" mean?

This pull ring means the hand pull ring that opens the can. This promotional slogan is very creative, haha. Pull tabs and environmental protection rhyme very well. I hope you can understand environmental protection from here

When taking the subway in Beijing, I can always see this story...a very creative public service advertisement

The love between pull tabs and cans

A pull tab only has one can.

In addition to a pull ring, a can also contains a lot of Coke inside.

The pull tab and the can are separated by the full amount of Coke. The Coke is hugged close to the pull tab, the can tightly fits the pull tab, and the pull tab tightly locks the Coke.

Griphook has no love, because the can’s heart is full of cola.

Coke also has no love, because Griphook does not let him go out to find love.

In this way, there is no love in the can because the Coke does not want to keep it.

The three guys were silent for a long time. Because Griphook loved the can, he stayed firmly on the top of the can and refused to open the door. This was also because this was the only place where he could lean against the can. .

So this bottle of Coke has never been opened.

Because Coke doesn’t like this dark, silent and cold place, his desire to move forward cannot be resolved by anything. Every day, he rushes through the cans looking for a breakthrough, waiting for an opportunity to slip out and see the world.

None of these three guys are happy and no one can fulfill anyone's love. Because they have no love for each other.

Suddenly one day, the pull tab was opened willingly. He gave up and no longer guarded the can like that. He decided to fulfill the love of the can and never wait endlessly again. Even if you face sacrifices, even if you never see the can again, don't be so unhappy anymore.

Coke rushed out with a shout of joy at the first time. The dazzling white light shot towards it. It was poured into the soft tongue, and the esophagus was dark again, but everything was so fresh.

When the Coke slowly poured out of the can, a lot of sorrow and sadness came up. Until the moment when the can was hollowed out, I suddenly felt enlightened. It turned out that Chengquan would be so relaxed and comfortable.

Can Can looked at the hole in his heart, and inadvertently thought of Griphook, thinking that Griphook, who accompanied him in obscurity, actually left an irreparable scar in his heart when he left. When I think of Coke, I can no longer remember what it looks like. I only remember the pain so many times, but I no longer remember how painful it feels.

Just as the can was immersed in the memory of the ring, a harsh metal collision sound accompanied by pain came. When he recovered from the pain, a huge sense of happiness enveloped Can Can, because when he opened his eyes, he saw Griphook's smile that he had not seen for a long time. No longer asking anything, no longer doubting anything, they hugged each other tightly (they were crushed together by a certain worker or machine and re-produced), cherishing each other, and never separated again. From then on, the can and the pull-hook lived happily and noisily together.
