Human impact on the environment (or anthropogenic environmental impact) refers to changes to biophysical environments [1] and to ecosystems, biodiversity, and natural resources [2] caused directly or indirectly by humans.
Most environmental health indicators, such as water and air pollution show an inverted U-shape. Meaning in the beginning of economic development, little weight is given to environmental concerns, raising pollution along with industrialization.
The scientific community has been investigating the causes of climate change for decades. After thousands of studies, it came to a consensus, where it is "unequivocal that human influence has warmed the atmosphere, ocean and land since pre-industrial times." [1] : 3 This consensus is supported by around 200 scientific organizations worldwide, [2] The dominant role in this climate change has ...
Air pollution is the introduction of chemicals, particulate matter, or biological materials into the atmosphere, causing harm or discomfort to humans or other living organisms, or damaging ecosystems. Air pollution can cause health problems including, but not limited to, infections, behavioral changes, cancer, organ failure, and premature death.
The simplest way to define an ecological footprint is the amount of environmental resources necessary to produce the goods and services that support an individual's lifestyle, a nation's prosperity, or the economic activity of humanity as a whole. [16] [8] The model is a means of comparing lifestyles, per capita consumption, and population ...
Pollution. The environmental effects of transport are significant because transport is a major user of energy, and burns most of the world's petroleum. This creates air pollution, including nitrous oxides and particulates, and is a significant contributor to global warming through emission of carbon dioxide. [2] [3] Within the transport sector ...
As with many countries, pollution in the United States is a concern for environmental organizations, government agencies and individuals. Pollution from U.S. manufacturing has declined massively since 1990 (despite an increase in production). A 2018 study in the American Economic Review found that environmental regulation is the primary driver ...
The modern Environmental movement, which began in the 1960s with concern about air and water pollution, became broader in scope to include all landscapes and human activities. See List of environmental issues.
