Digital pollution refers to the negative impact of digital technology and electronic waste on the environment and human health. This can include emissions from electronic devices, toxic chemicals in electronic waste, and the proliferation of e-waste in landfills. Technology users contribute to digital pollution on a daily basis, which include:
Computer monitors are typically packed into low stacks on wooden pallets for recycling and then shrink-wrapped. Recycling is an essential element of e-waste management. Properly carried out, it should greatly reduce the leakage of toxic materials into the environment and militate against the exhaustion of natural resources.
Computer virtualization refers to the abstraction of computer resources, such as the process of running two or more logical computer systems on one set of physical hardware. The concept originated with the IBM mainframe operating systems of the 1960s, and was commercialized for x86 -compatible computers, and other computer systems, in the 1990s.
This is causing concern about the ability of landfills to contain these materials and the possibility of these chemicals and drugs making their way into the groundwater and the surrounding environment. [9] Zero waste promotes a circular material flow that allows materials to be used over and over, reducing the need for landfill space. [10]
The World Computer Exchange accepts computer donations of electronics that they give to low-income communities worldwide. [113] Free Geek is a collectively run, non-profit organization based in Portland, Oregon. It aims to reuse or recycle used computer equipment that might otherwise become hazardous waste, and to make computer technology more ...
Air pollution is a widespread problem in India—nine out of the ten most polluted cities on earth are in India. [14] An important contributor to India's air pollution problem is widespread, improper recycling and disposal of e-waste. For example, dismantling and shredding of e-waste releases dust and particulates into the surrounding air.
Computer vision is used to monitor and track endangered species, such as tracking the movements of animals in their natural habitats or identifying individual animals for population studies. For example, camera traps equipped with computer vision algorithms can automatically detect and identify species, allowing researchers to study their ...
Multiple choice questions lend themselves to the development of objective assessment items, but without author training, questions can be subjective in nature. Because this style of test does not require a teacher to interpret answers, test-takers are graded purely on their selections, creating a lower likelihood of teacher bias in the results. [8]
