Perhaps the best evidence for this perturbation comes from air trapped in layers of quasipermanent ice in the Arctic and the Antarctic. Ice cores taken from these two polar regions give us a 2000‐year record of theHuman impacts on the nitrogen cycleImpacts on Productivity & Nutrient Cycling...
Each of these environmental effects can be magnified by the ‘nitrogen cascade’: a single atom of Nr can trigger a cascade of negative environmental impacts in sequence. Here, we provide an overview of the impact of Nr on the environment and human health, including an assessment of the ...
“How humans impact the Carbon‚ phosphorus‚ and nitrogen cycles” Christine Richardson Environmental Science May 1‚ 2013 The carbon cycle is based on carbon dioxide which is a very important element because it is a part of all life. All living things are made of elements such as oxygen...
Human alteration of the nitrogen (N) cycle has produced benefits for health and well-being, but excess N has altered many ecosystems and degraded air and water quality. US regulations mandate protection of the environment in terms that directly connect to ecosystem services. Here, we review the...

In 1962, Rachel Carson published the book “Silent Spring”, in which she mentioned problems that could arise from the indiscriminate use of pesticides. This book inspired widespread concern about the impact of pesticides on the human health and the environment. In 1967, Ratcliffe [4] noted incr...
s impact on the planet is overwhelming, but the changes are very recent in geological terms, where an epoch usually spans tens of millions of years. “One criticism of the Anthropocene as geology is that it is very short,” said Zalasiewicz. “Our response is that many of the changes ...
Nitrogen (N) is an essential element for all biological tissues, and the N cycle is one of the main biogeochemical cycles that can have a substantial and wide-ranging impact on the ecological environment1,2,3. Human activities have greatly changed the global N cycle and increased the creation...
(e.g., use of phosphate-based detergents) and regional, cultural, and differences in diet that impact the P content of feces and urine (Rose et al., 2015). For eco-prospecting, in addition to knowing the content of P present in greywater, feces, and urine, it is important to ...
region of 13.1 Tg yr−1. On a per area basis, however, the largest nitrogen fluxes are found in the highly disturbed watersheds around the North Sea, in northwestern Europe, and in the northeastern U.S., all of which have riverine nitrogen fluxes greater than 1,000 kg N km−2yr...
