New York, February 6 (IANS): Who does not love to sit at home in sweatpants and shop online? But it may not be as environment friendly option as often people think, new research suggests. Scientists have found that the total number of vehicles miles travelled has not decreased at all with the growth of online shopping. Home shopping has a greater impact on the transportation sector than the public might think in a study published in the International Journal of Sustainable Development and World Ecology. Though it's true that e-stores require less space and use less energy, online shopping puts more delivery trucks on the roads, which translates into more wear-and-tear on pavements and increased environmental pollution, said lead author Arde Faghri from University of Delaware in the US.
