The health and environmental impact of transport is significant because transport burns most of the world's petroleum.This causes illness and deaths from air pollution, including nitrous oxides and particulates, and is a significant cause of climate change through emission of carbon dioxide.
[1] [2] The pervasive presence of plastics in our environment has raised concerns about their long-term impacts on human health. While visible pollution caused by larger plastic items is well-documented, the hidden threat posed by nanoplastics remains under-explored. These particles originate from the degradation of larger plastics and are now ...
Environmental hazards are those hazards that affect biomes or ecosystems. [1] Well known examples include oil spills, water pollution, slash and burn deforestation, air pollution, ground fissures, [2] and build-up of atmospheric carbon dioxide. [3] Physical exposure to environmental hazards is usually involuntary [3]
Air pollution is the largest environmental risk factor for disease and premature death [5] [14] and the fourth largest risk factor overall for human health. [15] Air pollution causes the premature deaths of around 7 million people worldwide each year, [5] or a global mean loss of life expectancy (LLE) of 2.9 years, [16] and there has been no ...
