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.
Smog, or smoke fog, is a type of intense air pollution.The word "smog" was coined in the early 20th century, and is a portmanteau of the words smoke and fog [1] to refer to smoky fog due to its opacity, and odor. [2]
More pollution: People use more electricity for air conditioning, and cars emit more fumes, adding to pollution. Wildfires: Heat can cause wildfires, which release a lot of smoke and particles ...
Furthermore, rising air temperatures often improve ozone-forming processes, which has a repercussion on climate, as well. Ozone production rises during heat waves, because plants absorb less ozone. It is estimated that curtailed ozone absorption by plants could be responsible for the loss of 460 lives in the UK in the hot summer of 2006. [40]
Looking down from the Hollywood Hills, with Griffith Observatory on the hill in the foreground, air pollution is visible in downtown Los Angeles on a late afternoon.. Air pollution is the introduction of chemicals, particulate matter, or biological materials into the atmosphere that cause harm or discomfort to humans or other living organisms, or damage ecosystems.
Turning existing city infrastructure green by installing plants can filter out fine dust and noise, reduce urban heat island effects, and even reduce stress. All it takes is regreening 20 percent ...
The other product, nitrate (NO 3 −), is a key nutrient for plant growth. This excess nitrate from ammonia nitrification favors nitrophilous plants (those that prefer high nitrate concentrations) and disadvantages others. For example, an increase in nitrophilous plant populations shade other plants from necessary sunlight.
Whether the fake plant is warmed by the sun or stays cool when it is cold and dark has no bearing on any process within it: it is neither good nor bad for it. Because a real plant has a life of ...
