Before other countries could react, the island nation had already become a thing of the past.

Coastal nations have learned from this experience, strengthening their vigilance over the oceans while trying to understand the reasons behind the sudden ferocity of marine life.

After extensive investigation, the main cause was finally identified: the island nation had been dumping industrial wastewater and even nuclear wastewater into the ocean for years. Heavy metals and radiation caused some marine life to become ill or even die, and some marine life became more ferocious. Originally, this had little to do with the land, but the islanders moved to the seabed to escape zombies and continued to kill highly intelligent marine animals, which triggered this causal event.

The sins committed by humankind will inevitably be borne by humankind, and may even affect other creatures, although those who commit sins and those who bear the consequences may not be from the same generation.

The pollution that has already been caused is irreversible, and there are definitely other countries secretly dumping industrial wastewater into the sea as well.

Pollutants such as petroleum, metals, acids and alkalis, pesticides, radioactive substances, organic waste liquids and domestic sewage, thermal pollution and solid waste seriously affect water quality and marine life, thereby affecting human production and life and threatening human health.

Even disregarding the harm to the natural environment, polluting the ocean is not a wise move if we only consider human beings. Yet some people are willing to step on the corpses of others to make money, just to save on the cost of garbage disposal.

When Yan Shi heard this news, his good mood of the past few days vanished completely.

“I feel sorry for those dolphins and whales. I just learned that a dolphin once committed suicide because it lived in an aquarium for many years and was constantly subjected to unbearable sounds. It chose not to breathe and suffocated itself.”
