Streets may have enhanced the capability of the human being to take a voyage across all over the world with more convenience and easiness. But it has also created a state of peril for the preservation of natural legacy. As per a recently published study, human-made streets have sliced the surface of the Earth into billion of pieces.
A group of scientists from the Eberswalde University for Sustainable Development in Germany, during a study on roadless areas, have found that the manmade roads have divided the surface of the Earth into more than 600,000 pieces, which in other ways is hampering the capability of the nature to run ecology smoothly. The researcher has taken a dataset of 36 million kilometers roads across the world into account for conducting the survey and found that, apart from the transportation easiness, roads are creating immense issues for the ecological functionalities. The scientists also cautioned that the human-made roads are creating negative impacts on the earth and is also lessening the capacity of the ecosystem to run productively.
As per the road statistics, by the end of 2050, the government is planning to pave 25 million kilometers more streets across the globe. While from a certain point of view, the development is positively contributing to the growth of global economy, on the other hand, it is also creating hazards for the ecology.
According to the survey, manmade roads have already carved the Earth’s surface into around 600,000 slices, among which, more than half are less than 1 square kilometer in dimension. In addition, among these 600,000 pieces, only 7% are more than 100 square km. The scientists, in the published research paper also mentioned that the largest roadless tracts are found in the tundra and the boreal forests of North America and Eurasia. Some are also discovered in tropical tracts in Africa, South America, and Southeast Asia. But, unexpectedly, only 9% of these uninterrupted areas are reported to be sheltered.
“The growing amount and a number of manmade roads are breaking off the stream of the chromosome in the animal populace, the study revealed. And this break off is enabling them to increase pests and infection among others creatures. In addition, this interpreting flow is also triggering more soil erosion and the contamination of wetlands and water bodies”.
