At the national level, bamboo represents a high level of fresh air, which is of great use both for gardening and spring cooking and for making furniture and tools for farming. But the same bamboo drifted across the sea to the united states, and the situation turned upside down: a number of states in the united states clearly controlled the most productive scaffolds, many neighbours went to court because of the mackerel that ran underground, and locals called out-of-control bamboo forests “green cancer”。
Why is it so different between china and america? It is not the bamboo itself that is the problem of this hundred-year-long sprawl of bamboo, but rather the unaffordable price that the americans paid for ignoring ecological patterns and breaking the natural balance。
Bamboos have spread wild, and countless american families have lost their lives
There is an unwritten rule for buying a house in the united states: it is hard to sell a house that has been planted in the yard. The bamboo roots grow horizontally, with extreme permeability, which, for a long period of time, tears the foundations and piercs the groundwater pipes, as a result of which many economic disputes arise。
There was a widespread lawsuit in new jersey: a family had planted bamboo in the yard early in the year, and in a few years it had drilled through the ground, breaking its neighbours' foundations, breaking water pipelines, and a large collapse of the floor. The court eventually awarded the grower compensation of nearly $200,000, which would have enabled the purchase of almost half of the local common dwelling。
California, which has been under fire for many years, is a major safety hazard. The plume is empty, dry and easily burned, and a series of bamboo forests form a fire channel that accelerates the spread of the mountain fires, and there have been numerous instances of entire residential areas being burned by fires set by the plume。
A rancher in alabama was particularly affected, and the bamboo planted next door, 20 years ago, continued to expand into his own pasture, killing large areas of herb. In order to clean up all the bamboo roots on the ground and repair the rangeland, he worked for more than four consecutive months at a cost of over $300,000。
It is difficult for anyone to accept a house that they have bought and a land on which they have made a living, which they have destroyed silently。
There's no proliferation of bamboo in the country
A lot of people wonder that bamboo is visible in the country's mountains and in the yard, but it never goes out of control and goes crazy, and the core is two layers of natural restraint in our own country。
In the wild, there are insects that depend exclusively on bamboo for survival, with bamboo phids eating young, bamboo and locust infestation leaves that naturally limit the unrestricted reproduction of bamboo; on the other hand, the population has been accustomed for centuries to using bamboo rationally to control quantities from sources. In spring spring, spring and winter are used as food, and in autumn and winter, old bamboo poles are cut off to weave and build, and the bamboo forest will not be allowed to expand indefinitely。
From the emergence of bamboo, to the formation of old bamboo, the country's bamboo forests have been restricted in both directions by pests, artificial harvesting, and growing on a manageable scale without extensive encroachment on other plant areas。
Hastily inducing soil and water conservation plants to bury 100 years of ecological hazards
At the end of the nineteenth century, the united states experienced heavy soil erosion, landslides and land salinization. The bamboo roots are deep, growing fast and solid soil has a strong effect, when agricultural researchers called the great green wall from the east。
Without an earlier assessment of the risk of alien species locally, cultivation is widespread throughout the country, ignoring the lack of indigenous conditions to contain bamboo. There are no primary bamboo-dependent insects on the mainland of the united states, and there is no habit on the part of the local population of digging, cutting and using bamboo, and the fact that many areas are humid and fertile, leaving bamboo completely free from growth constraints。
The loss of natural enemies and manual control has led to the uncontrolled spread of bamboo roots beneath the ground, the seizure of indigenous plants, crops, and the invasion of agricultural land, gardens and pastures, which was used to repair ecological plants and turned into an ecological problem of cross-state proliferation。
It's very expensive to clear the bamboo forest. All available options are short
The old saying is that god is easy to deal with. Today, many states in the united states have banned the cultivation of aggressive bamboo, but it is difficult to clean up the mackerel that has spread over the centuries。
Direct digging is the most common method, and, according to the homeadvisor industry offer, ordinary small homes will cost tens of thousands of dollars to clear bamboo roots and, in the case of a few acres of mackerel wood, tend to cost more than $100,000. The construction requires deep excavations, and if only a small piece of bamboo remains in the soil, it will re-emerge in the coming year, not only to spend time but also to easily destroy the foundations and layers of the original house。
The spraying of herbicides can only burn the poles on the ground, and it is difficult to eradicate and treat the roots of the bamboo buried in the ground; strong herbicides also contaminate soil water sources and damage indigenous green plants, which are restricted by environmental regulations and cannot be used extensively。
The proposal to introduce domestic bamboo-eating insects to counterbalance bamboo forests was finally rejected. Australia's hares and asian carp in the u. S. Riverway are the first ones, and experts fear that when new insects are introduced, they will once again spread out of their existing constraints, resulting in a new wave of biological invasion。
Money, pollution of the environment and the existence of secondary risks are clearly flawed in all three forms of governance, and humankind has so far been unable to fully address the disaster。
All things grow with checks and balances
The shift of bamboo from landscape plants to ecological disasters is the same as the proliferation of wild rabbits in australia and the crowding of carp in asia on the american channel. The ecology of each piece of land evolves over the course of millions of years into a stable cycle in which natural enemies, climates and soils hold each other hostage and maintain balance。
The artificial introduction of alien plants and animals amounts to a forced disruption of a stable natural system, which in the short term appears to solve a small problem and triggers a series of irreversible damage in the long term. The ancients say that “orange is a small south, but also an orange, born in a small north”, and that plants are still subject to geographical constraints, and that human intervention is simply not free。
The 100-year-long proliferation of bamboo is a wake-up call for all: not to bring wild animals and plants into the country at will, not to leave alien species behind, to look like little things, and could cause enormous economic losses and ecological damage in the future. If you have seen other invasive alien species that are difficult to clean up, you are welcome to share this in the comment area and to focus on ecological conservation。
