Pollution , also called environmental pollution , the addition of any substance solid , liquid , or gas or any form of energy such as heat , sound, or radioactivity to the environment at a rate faster than it can be dispersed, diluted, decomposed, recycled, or stored in some harmless form. The major kinds of pollution, usually classified by environment, are air pollution , water pollution , and land pollution.
An environmental hazard is a substance, state or event which has the potential to threaten the surrounding natural environment or adversely affect people's health , including pollution and natural disasters such as storms and earthquakes. It can include any single or combination of toxic chemical, biological, or physical agents in the environment, resulting from human activities or natural processes, that may impact the health of exposed subjects, including pollutants such as heavy metals, pesticides, biological contaminants, toxic waste, industrial and home chemicals. Human-made hazards while not immediately health-threatening may turn out detrimental to a human's well-being eventually, because deterioration in the environment can produce secondary, unwanted negative effects on the human ecosphere.
You were introduced to wastes and pollutants in Study Session 1, where we discussed the interactions between humans and our environment. Pollution was defined as the introduction into the environment of substances liable to cause harm to humans and other living organisms. Many human activities pollute our environment, adversely affecting the water we drink, the air we breathe, and the soil in which we grow food. In this and the next study session we will look more closely at pollution. In this session you will learn about the different types and sources of pollution and the various human activities that can cause pollution. We will also describe the ways pollution can affect different sectors of the environment: water, air and soil. Study Session 8 describes some of the significant effects of pollution on the environment and on human health.
Man-made pollutants can threaten human health and compromise the natural ecosystem and environment. Man-made pollution is generally a byproduct of human actions such as consumption, waste disposal, industrial production, transportation and energy generation. Pollutants can enter the surrounding environment in various ways, either through the atmosphere, water systems or soil, and can persist for generations if left untreated. Air pollution occurs when harmful chemicals or particulate matter are introduced into the atmosphere. Depending on the type and severity, air pollution can damage human and animal health as well as the natural environment.
Air Quality. What one experiences today as atmosphere is a transient snapshot and result of its evolutionary history. Much of the development and present status was explained based both on scientific knowledge, and combined with established facts, even speculation. The planet Earth was formed around million years ago by the gravitational accretion of relatively small rocks and dust, within the solar nebula. The first evidence of single-celled life, for which tiny oxygen concentration was an essential prerequisite, is shown in the fossil record from around million years ago.

Without action, the challenges will only increase by , when global demand for freshwater is expected to be one-third greater than it is now.

Далее в заметке сообщалось, что, хотя алгоритм вызвал громадный интерес в Японии, несколько американских производителей программного обеспечения, прослышавших о Цифровой крепости, считают эту информацию нелепой - чем-то вроде обещания превратить свинец в золото.

The major difference between natural and man-made air pollution is that continuous or temporary natural events cause natural air pollution, but human activities are responsible for man-made pollution.
