Petroleum extraction disrupts the equilibrium of earth's carbon cycle by transporting sequestered geologic carbon into the biosphere. The carbon is used by consumers in various forms and a large fraction is combusted into the atmosphere; thus creating massive amounts of the greenhouse gas, carbon dioxide, as a waste product.
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:
When used in the workplace, AI also presents the possibility of new hazards. These may arise from machine learning techniques leading to unpredictable behavior and inscrutability in their decision-making, or from cybersecurity and information privacy issues. Many hazards of AI are psychosocial due
Electric vehicles use much more lithium carbonate equivalent in their batteries compared to the 7g (0.25 oz) for a smartphone or the 30 g (1.1 oz) used by tablets or computers. As of 2016, a hybrid electric passenger car might use 5 kg (11 lb) of lithium carbonate equivalent, while one of Tesla 's high performance electric cars could use as ...
Nutrient pollution, a form of water pollution, refers to contamination by excessive inputs of nutrients.It is a primary cause of eutrophication of surface waters (lakes, rivers and coastal waters), in which excess nutrients, usually nitrogen or phosphorus, stimulate algal growth. [1]
In fact, due to long-term impacts on food webs, Nr inputs are widely considered the most critical pollution problem in marine systems. [8] In both terrestrial and aquatic ecosystems, responses to N enrichment vary; however, a general re-occurring theme is the importance of thresholds (e.g., nitrogen saturation) in system nutrient retention ...
The expression was popular in the early days of computing. The first known use is in a 1957 syndicated newspaper article about US Army mathematicians and their work with early computers, [4] in which an Army Specialist named William D. Mellin explained that computers cannot think for themselves, and that "sloppily programmed" inputs inevitably lead to incorrect outputs.
Liquid helium, colder than liquid nitrogen, has also been used for cooling. Liquid helium boils at −269 °C (−452.20 °F), and temperatures ranging from −230 to −240 °C (−382.0 to −400.0 °F) have been measured from the heatsink. [47] However, liquid helium is more expensive and more difficult to store and use than liquid nitrogen.
