Preamble:
Where did the old turtle in the ditch go? The "longevity ingredients" that were readily available in my memory quietly disappeared into the cracks of time.
However, while people are still nostalgic for the delicacy of the old turtle, a large and menacing "outsider" quietly occupies their place.
What is the story behind this "battle of the century" between native and alien species?
Let's unravel this mystery together and explore the subtle changes in the relationship between man and nature behind the disappearance of the old turtle and the dominance of the Florida turtle. This is not only a story of species replacement, but also a cautionary tale about ecological balance and sustainable development.
The mysterious disappearance of the native turtle: the "king" of the eighties and nineties, now disappears
The old turtle, a species that once "reigned supreme" in the rural waters of the mainland, has gradually faded out of people's field of vision. In the eighties and nineties, almost every child who grew up in the countryside had the experience of catching turtles in a ditch.
At that time, the turtle was all over the fields, like the "king" of the water world. Catching the old turtle is not only the joy of eating a delicious meal, but also a proud "trophy".
However, just when people are still immersed in the beauty of childhood memories, reality has issued a warning: nowadays, it is becoming more and more difficult to see the old turtle in the wild.
The reason for the mysterious disappearance of the old turtle is actually not difficult to find. As a species accustomed to living in silt and swamps, the old turtle has an extremely tenacious vitality.
They are able to survive in extreme environments and need little to no food to stay alive. At the same time, the old turtle also has an amazing reproductive ability, laying dozens of eggs at a time, and without careful care, the young turtles can break out of their shells and thrive. These characteristics should have made the turtle a long-lasting species, but human activities have upset this natural balance.
With the development of the economy, the waters in the countryside are shrinking, and the homes that the old turtles rely on for survival are disappearing little by little. At the same time, the demand for turtle meat is increasing day by day.
Driven by profits, the number of wild turtles has plummeted due to heavy fishing, and in some areas there is even a danger of extinction.
Faced with the dilemma of the old turtle, people began to try to save this species through artificial breeding. In some areas, special soft-shelled turtle breeding bases have been set up, hoping to meet market demand and reduce pressure on wild populations.
However, is artificial breeding really a panacea for saving the turtle? Facts have proved that in the breeding environment, the growth rate and reproductive ability of the turtle are not as good as before, and many farms are even difficult to maintain operation.
More importantly, artificially bred turtles cannot completely replace the role of wild populations in the ecosystem.
In order to truly restore the old turtle population, it is essential to protect the natural environment on which they depend. This requires us to reflect on the relationship between man and nature, and leave enough space for wildlife to survive while developing the economy.
Invasive alien species Florida soft-shelled turtle: From pet to "bully", it dominates continental waters
When people were still immersed in the fun of catching turtles in childhood, an uninvited guest quietly came.
This alien species from the United States, once popular as a pet, and had high hopes for its breeding prospects, but who would have thought that this creature called the Florida turtle would become a "bully" in mainland waters in just a few decades, trampling on the fragile ecological balance.
The invasion of the Florida soft-shelled turtle began in the eighties and nineties of the last century. At that time, the popularity of the pet market brought this tame and cute turtle into people's field of vision.
At the same time, the number of native soft-shelled turtles in China is becoming increasingly scarce due to overfishing, and in order to fill the market gap, some people have set their sights on Florida soft-shelled turtles. As everyone knows, this seemingly innocuous move has laid the groundwork for the future ecological catastrophe.
When the Florida turtle enters the continental waters, it is as if it has come to heaven. It has a suitable climate, plenty of food, and no predators.
As a result, these "super turtles", which are several times the size of the native soft-shelled turtles, began to multiply wildly, expanding their populations at an alarming rate.
Florida soft-shelled turtles, which often weigh dozens of pounds, appear frequently, and the fish, shrimp and crabs in the water are all in their stomachs, and even insects and earthworms cannot escape their fate. Their strong adaptability allows them to be at home on the shore, and this all-round survival advantage makes the Florida soft-shelled turtle population like a never-ending machine, spreading freely in the rivers and lakes of the mainland.
Today, the Florida soft-shelled turtle is the number one threat in mainland waters. Not only do they take away space and food for native species, but they are also likely to carry dangerous viruses and parasites, which can wipe out local ecosystems.
From north to south, from east to west, this alien invader has spread all over the country, posing an unprecedented challenge to the continent's biodiversity.
In the face of such a "bully," how should we deal with it? Should we let it run rampant, or should we kill the killers? Can hunting and eating curb its frenzied expansion, or will it bring more hidden ecological dangers? These questions require us to use wisdom and action to explore the answers.
Warning of invasive alien species: The ecological balance is in jeopardy, and management needs to be strengthened urgently
Globally, invasive alien species have become a growing ecological problem. From water hyacinth in the Amazon, to rabbits in Australia, to Spartina alterniflora on the mainland, species are spreading in exotic lands, causing a huge impact on local ecosystems.
The mainland, as one of the most biodiverse countries in the world, is facing a huge threat of invasive alien species.
According to statistics, more than 600 invasive alien species have been discovered on the mainland, including many "bullies" like the Florida soft-shelled turtle, which not only occupies the living space of native species, but also may carry viruses and parasites, bringing serious losses to human health and economic development.
In many cases of alien species invasion, human activities have almost always played the role of "accomplices". Pet trade, intentional introductions, species escapes...... Seemingly harmless behavior, but it opens the door to the invasion of alien species.
In the case of the Florida soft-shelled turtle, it is precisely because of the needs of the pet market and the consideration of filling the gap of native soft-shelled turtles that this species has been "legally" entered the mainland. As everyone knows, when we change the distribution range of a species, it is likely to break the original ecological balance and bring about a series of chain reactions.
What is even more worrying is that many alien species invasion problems did not attract enough attention at the beginning of the discovery, and when there is a large-scale outbreak, it is even more difficult to control it.
So, how do we deal with the challenges posed by the invasion of alien species? The answer lies in strengthening management and prevention and control. This requires not only improving relevant laws and regulations to strictly restrict the introduction and trade of alien species, but also strengthening quarantine supervision to detect and stifle the "germination" of invasion in a timely manner.
At the same time, raising public awareness is crucial. Many invasive alien species are able to spread rapidly precisely because people lack awareness of their harmfulness and even inadvertently "help" them. Only by making everyone a conscious actor in protecting the ecological environment can we build a solid line of defense against the invasion of alien species.
The disappearance of the old turtle and the proliferation of the Florida soft-shelled turtle have sounded the alarm for the conservation of biodiversity on the mainland.
Their stories tell us that when the ecological balance is upset, the consequences can be unimaginable. The invasion of alien species is just one of the thought-provoking microcosms. From a broader perspective, there is an urgent need to strengthen biodiversity conservation and maintain the balance and stability of ecosystems.
It's not just about the fate of wildlife, it's about the future of us as human beings. Only by examining the relationship between man and nature with the vision of development and the concept of ecological civilization, and taking care of the home on which we live, can we achieve the harmonious coexistence of man and all things.
Harmonious coexistence between man and nature: abandon anthropocentrism and think from an ecological perspective
The invasion of the Florida soft-shelled turtle is a microcosm of the self-interested thinking pattern of human beings. At the beginning, we introduced this species, either out of the needs of the pet market, or to fill the vacancy of native soft-shelled turtles, and it seemed that we were serving our own interests.
As everyone knows, under this kind of thinking centered on human needs, we ignore the importance of ecological balance.
We arbitrarily alter the range of a species, upsetting the delicate balance that nature has developed over hundreds of millions of years of evolution. The proliferation of Florida soft-shelled turtles is the result of this anthropocentrism.
From the disappearance of the old soft-shelled turtle, to the rise of the Florida soft-shelled turtle, to the frequent invasion of alien species, all reflect the far-reaching impact of human activities on the ecological environment. We are accustomed to measuring everything by the scale of economic interests, but we forget that nature has its own laws of operation.
When we arbitrarily intervene or even destroy this law for the sake of temporary profits, we must bear the consequences of ecological imbalance. And this consequence is often all-round, long-term, and even irreversible.
In the face of growing ecological challenges, we need to learn from the story of the Florida soft-shelled turtle. This requires us to reflect on the relationship between man and nature, abandon the arrogance of anthropocentrism, and understand and respect the laws of nature with a more humble attitude.
We need to realize that human beings are only a member of the natural world, and to maintain biodiversity and protect the ecological environment, not only for the sake of wildlife, but also for ourselves.
Only by abandoning the myth that "man will conquer heaven" and examining our words and deeds with the concept of ecological civilization can we achieve a harmonious coexistence between man and nature.
Epilogue:
The disappearance of the old turtle and the proliferation of the Florida soft-shelled turtle reflect the profound impact of human activities on the natural ecology. Our vaunted idea that "man conquers heaven" may inadvertently upset the balance of nature.
This story tells us that man and nature are a community with a shared future, and we must treat every species with reverence, respect the laws of nature, and maintain biodiversity.
Only by abandoning anthropocentrism and guiding our behavior with the concept of ecological civilization can we achieve a harmonious coexistence between man and nature. Let's work together to protect the land we live on and leave a green and sustainable home for future generations.
