World’s Most Serious Environmental Crisis: Oxygen disappearing from the Air (with David Cardill)

Physicist and engineer David Kadir absolutely pointed out the most serious environmental crisis: to lower the oxygen level in most areas. Internal combustion engines (thousands of cars and trucks all over the world) are consuming oxygen in our atmosphere. This is why birds are dead and spring is silent. "When a bee leaves, humans are only four years away" - Albert Einstein

In addition, oxygen is necessary for human survival and our oxygen is the supplier of the most important green environment for forests, so pollution is the most serious problem everyone must deal with, especially the atmosphere It is pollution. In addition, although we have been taught business ethics theory in our education, there are still people who continue deforestation. Therefore, regulations and regulations (bills) should treat all inevitable people strictly to forest reserves.

In the most prominent signs of the ecological crisis, the destruction of the world's forests is the most annoying due to the severity of its impact. In the past 50 years, one-third of the world's forest has disappeared. This is the biggest blow to the tropical countries. In advanced industrialized countries, the areas with trees are relatively stable, but the forests have gradually declined due to air pollution, oil pollution, and soil contamination. However, in the Third World, deforestation is at the center of the ecological crisis. Forest logging is the result of a vicious circle of poverty and depletion of cultivated land. Another reason is not excessive felling of tropical forests, not sustainable management. This impairs biodiversity - tropical forests offer cheap products to Western buildings and furniture markets due to over 50% of the species of animals and plants on Earth - and resources of the forest population.

Air pollution is one of the most serious environmental problems in urban areas around the world. Urbanization and urban air pollution is becoming an increasingly serious problem due to the rapid process of urbanization and widespread energy use (mainly due to rapid economic expansion and population increase over the past decades). Air contains varying degrees of pollutants from automotive, industrial, residential and commercial pollution sources. The influence of air pollution has exerted multifaceted influence on human happiness in the fields of health, agriculture, ecosystem etc. It is worth noting that many studies show that air pollution can adversely affect human health. PM 10 and PM 2.5 are expressed particles with sizes of 10 μg and 2.5 μg or less, ie PM 10 and PM 2.5, sulfur dioxide (SO 2) and ozone have a significant health impact. Epidemiological evidence confirms the relevance between exposure to these environmental air pollutants and various health effects such as respiratory symptoms and diseases (eg,
