Airborne Toxics

1
Airborne Toxics

• Airborne Toxics are less catastrophic but highly
  worrisome air pollution threats 2.4 billion
  pounds of airborne toxic substances released
  annually into the nation's atmosphere, including
  phosgene, a nerve gas used in warfare, and methyl
  isocyanate.

Water pollution

• Water pollution is likewise a serious problem.
  About 40 of the world's surface water is too
  polluted to fish or swim in.
• Pollution comes from agriculture, mines, oil
  wells, human wastes, manufacturing, detergents,
  and the food industry, among other sources.
• Today, almost 1 billion people lack access to
  safe water and the worlds per capita supplies of
  water are shrinking.

Health Hazards

• The pollution of the land by toxic substances
  also causes increased mortality and illness.
• Hazardous or toxic substances are those that can
  cause an increase in mortality rates or
  irreversible /incapacitating illness, or those
  that have other seriously adverse health or
  environmental effects.

• Over 58,000 different chemical compounds are
  currently being used in the U.S. and the number
  is increasing each year. How many of these
  chemicals affect humans, no one really knows.
• The sheer volume of solid waste is staggering
  each U.S. resident produces about seven pounds of
  garbage per day.

5
Chemical Wastes

• Though this quantity is massive, it is not even
  close to the quantity of industrial waste.
• The EPA estimates that about 15 million tons of
  toxic waste is produced in the U.S. each year.
• This does not include nuclear wastes, which,
  because they are so concentrated and persistent,
  present special problems for storage and
  disposal.

6
Chemical Wastes

• Each nuclear reactor produces 265 pounds of
  plutonium waste a year, a substance so toxic that
  only twenty pounds would be sufficient to cause
  lung cancer in everyone on Earth.
• So far, no one really knows how to dispose of
  this and similar wastes safely and securely.

Definition of Greenness

• Being Green as a slogan
• Areas of Concern
• Preservation of environment.
• Avoidance of pollution.
• Conservation of energy.
• Depletion of raw material.
• Animal welfare and species preservation.
• Noise pollution.
• Prohibition on smoking at work place.

8
Conceptualization of Greenness

• Holism a conception of nature wherein humans and
  nature together form a moral community. i.e. to
  see the earth as a whole rather than to take
  decisions which only benefit on single part, such
  as ones personal profit at the expense of
  environmental damage, or human well being at the
  expense of animal and plant life.

9
Conceptualization of Greenness

• Materialism earth is good it is worth
  preserving, and it is crucially important that it
  be preserved before irretrievable damage is done.

• we are coming close to the depletion point of
  fossil fuels. Minerals are also being depleted,
  so we can expect them gradually to become more
  scarce and expensive. This scarcity will have a
  serious impact on the world economy.
