    This creates air pollution, including nitrous oxides and particulates, and is a significant contributor to global warming through emission of carbon dioxide, [275] for which transport is the fastest-growing emission sector. [276] By subsector, road transport is the largest contributor to global warming. [275]

    The target satellite orbited between 850 km (530 mi) and 882 km (548 mi), the portion of near-Earth space most densely populated with satellites. [98] Since atmospheric drag is low at that altitude, the debris is slow to return to Earth, and in June 2007 NASA's Terra environmental spacecraft maneuvered to avoid impact from the debris. [99]

    en.wikipedia.org/wiki/Environmental_issues

    Environment destruction caused by humans is a global, ongoing problem. [4] Water pollution also cause problems to marine life. [5] Some scholars believe that the projected peak global population of roughly 9-10 billion people could live sustainably within the earth's ecosystems if humans worked to live sustainably within planetary boundaries.

  5. Air pollution - Wikipedia

    en.wikipedia.org/wiki/Air_pollution

    Air pollution can occur naturally or be caused by human activities. [4] Air pollution causes around 7 or 8 million deaths each year. [5] [6] It is a significant risk factor for a number of pollution-related diseases, including heart disease, stroke, chronic obstructive pulmonary disease (COPD), asthma and lung cancer.

    An October 2017 report published in The Lancet stated that toxic air, water, soils, and workplaces were collectively responsible for nine million deaths worldwide in 2015, particularly from air pollution which was linked to deaths by increasing susceptibility to non-infectious diseases, such as heart disease, stroke, and lung cancer. [34]

  7. Environmental degradation - Wikipedia

    en.wikipedia.org/wiki/Environmental_degradation

    Environmental degradation is the deterioration of the environment through depletion of resources such as quality of air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable.

  8. Particulate pollution - Wikipedia

    en.wikipedia.org/wiki/Particulate_pollution

    In 2006, the EPA conducted air quality designations in all 50 states, denoting areas of high pollution based on criteria such as air quality monitoring data, recommendations submitted by the states, and other technical information; and reduced the National Ambient Air Quality Standard for daily exposure to particulates in the 2.5 micrometers ...

    Some of the hazardous damage of oil and gas exploration in the ecosystem are life threatening which includes Air pollution, Water pollution, Noise pollution etc. Affecting the aquatic lives, human health, also leads to deforestation. According to Nigerian federal government figures, there were more than 7,000 oil spills between 1970 and 2000. [66]
