Nutrient pollution is a form of water pollution caused by too many nutrients entering the water. 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. Sources of nutrient pollution include surface runoff from farms, waste from septic tanks, feedlots, and emissions from burning fuels. Raw sewage, which is rich in nutrients, is also a contributing factor when dumped in water bodies. Excess nitrogen causes environmental problems such as harmful algal blooms, hypoxia, acid rain, nitrogen saturation in forests, and climate change. Agricultural production relies heavily on th…

Quantifying environmental co-benefits of nitrogen-based crop restructuring and its implications on India's interstate trade network.. Addressing sustainability within food systems is challenging due to their multifaceted nature. Here, we evaluate crop-restructuring pathways for Indian agricultural system by integrating nutrient, water, greenhouse gas, economic, and interstate trade-network accounting. We show that the nitrogen-focused crop restructuring strategy reduces nitrogen surplus by 13.4% and water use by 18.6%. This approach maintains baseline calorie production, narrows the benchmarked cereal net-return deficit, and mitigates greenhouse gas emissions by 8.7%. Relative to water-focu…

Pollution is the introduction of contaminants into the natural environment that cause harm. Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Although environmental pollution can be caused by natural events, the word pollution generally implies that the contaminants have a human source, such as manufacturing, extractive industries, poor waste management, transportation or agriculture. Pollution is often classed as point source (coming from a highly concentrated specific site, such as a factory, mi…

Agricultural pollution problem refers to biotic and abiotic byproducts of farming practices that result in contamination or degradation of the environment and surrounding ecosystems, and/or cause injury to humans and their economic interests. The pollution may come from a variety of sources, ranging from point source water pollution (from a single discharge point) to more diffuse, landscape-level causes, also known as non-point source pollution and air pollution. Once in the environment these pollutants can have both direct effects in surrounding ecosystems, e.g. killing local wildlife or contaminating drinking water, and downstream effects such as dead zones caused by agricultural runoff i…

Health Consequences of Large Data Centers: Air Pollution, Noise, Water Use, and Environmental Justice. The global expansion of large, energy-intensive data centers, accelerated by cloud computing, cryptocurrency, and artificial intelligence (AI), has created growing concern about implications for human health. Emerging scholarship highlights multiple health-relevant pathways: increased emissions of criteria air pollutants from power plants and onsite diesel backup generators, chronic environmental noise from cooling infrastructure, intensive water withdrawals that strain public supplies, and land-use changes that intersect with social determinants of health. Direct epidemiologic evidence on…

Biological consequences of environmental pollution in running water ecosystems: A case study in zooplankton

Evidence: 47 • authority: 72

Water pollution (or aquatic pollution) is the contamination of water bodies, which has a negative impact on how they can be used. It is usually caused by human activities. Water bodies include lakes, rivers, oceans, aquifers, reservoirs and groundwater. Water pollution results when contaminants mix with these water bodies. Contaminants can come from one of four main sources. These are sewage discharges, industrial activities, agricultural activities, and urban runoff including stormwater. Water pollution may affect either surface water or groundwater. This form of pollution can lead to many problems. One is the degradation of aquatic ecosystems. Another is spreading water-borne diseases whe…

Quantifying the role of nitrogen in achieving global Sustainable Development Goals.. Achieving the 2030 Sustainable Development Goals (SDGs) requires balancing well-being with environmental protection, yet the role of nitrogen across these goals remains poorly understood. Here, we show how dietary nitrogen intake and nitrogen release to air and water are associated with SDG progress across 166 countries from 2000 to 2022. Higher per-capita nitrogen intake is positively associated with social and economic SDGs, whereas nitrogen release is negatively associated with environmental goals. Economic development is linked to improved SDG performance but also to greater dietary nitrogen demand and…

Surface runoff (also known as overland flow or terrestrial runoff) is the unconfined flow of water over the ground surface, in contrast to channel runoff (or stream flow). It occurs when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate into the soil. This can occur when the soil is saturated by water to its full capacity, and the rain arrives more quickly than the soil can absorb it. Surface runoff often occurs because impervious areas (such as roofs and pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or human-made processes. Surface runoff is a major component of the water cyc…

Eutrophication is a general term describing a process in which nutrients accumulate in a body of water, resulting in an increased growth of organisms that may deplete the oxygen in the water; i.e. the process of too many plants growing on the surface of a river, lake, etc., often because chemicals that are used to help crops grow have been carried there by rain. Eutrophication may occur naturally or as a result of human actions. Manmade, or cultural, eutrophication occurs when sewage, industrial wastewater, fertilizer runoff, and other nutrient sources are released into the environment. Such nutrient pollution usually causes algal blooms and bacterial growth, resulting in the depletion of d…

The environmental impact of agriculture varies widely based on practices employed by farmers and by the scale of practice. Farming communities that try to reduce environmental impacts through modifying their practices will adopt sustainable agriculture practices. The negative impact of agriculture is an old issue that remains a concern even as experts design innovative means to reduce destruction and enhance eco-efficiency. Animal agriculture practices tend to be more environmentally destructive than agricultural practices focused on fruits, vegetables and other biomass. The emissions of ammonia from cattle waste continue to raise concerns over environmental pollution. When evaluating envir…

The environmental impact of the energy industry is significant, as energy and natural resource consumption are closely related. Producing, transporting, or consuming energy all have an environmental impact. Energy has been harnessed by human beings for millennia. Initially it was with the use of fire for light, heat, cooking and for safety, and its use can be traced back at least 1.9 million years. In recent years there has been a trend towards the increased commercialization of various renewable energy sources. Scientific consensus on some of the main human activities that contribute to global warming are considered to be increasing concentrations of greenhouse gases, causing a warming eff…
