BIGGEST THREAT TO EARTH?

gt URBAN ENVIRONMENTAL PROBLEMS

11
DEFINITION
  • Localized environmental health problems such as
    inadequate household water and sanitation and
    indoor air pollution.
  • City-regional environmental problems such as
    ambient air pollution, inadequate waste
    management and pollution of rivers, lakes and
    coastal areas.
  • Extra-urban impacts of urban activities such as
    ecological disruption and resource depletion in a
    citys hinterland, and emissions of acid
    precursors and greenhouse gases.
  • Regional or global environmental burdens that
    arise from activities outside a citys
    boundaries, but which will affect people living
    in the city

  • MOST DANGEREOUS PART OF
  • URBAN DEVELOPMENT POLLUTION ?

PLASTIC BAGS
14
  • Plastic shopping bags are among the most
    ubiquitous consumer items on Earth. Their light
    weight, low cost, and water resistance make them
    so convenient for carrying groceries, clothing,
    and other routine purchases that it's hard to
    imagine life without them. Weighing just a few
    grams and averaging a few millimeters in
    thickness, plastic bags might seem thoroughly
    innocuouswere it not for the sheer number
    produced. Factories around the world churned out
    a whopping 4-5 trillion of them in 2002, ranging
    from large trash bags to thick shopping totes to
    flimsy grocery sacks

15
  • Compared with paper bags, producing plastic
    ones uses less energy and water and generates
    less air pollution and solid waste. Plastic bags
    also take up less space in a landfill. But many
    of these bags never make it to landfills
    instead, they go airborne after they are
    discardedgetting caught in fences, trees, even
    the throats of birds, and clogging gutters,
    sewers, and waterways. To avoid these impacts,
    the best alternative is to carry and re-use your
    own durable cloth bags.

16
DO YOU KNOW

17
  • Plastic bags start as crude oil, natural gas, or
    other petrochemical derivatives, which are
    transformed into chains of hydrogen and carbon
    molecules known as polymers or polymer resin.
    After being heated, shaped, and cooled, the
    plastic is ready to be flattened, sealed,
    punched, or printed on.
  • The first plastic baggies for bread,
    sandwiches, fruits, and vegetables were
    introduced in the United States in 1957. Plastic
    trash bags started appearing in homes and along
    curbsides around the world by the late 1960s.

18
  • A quarter of the plastic bags used in wealthy
    nations are now produced in Asia.
  • Each year, Americans throw away some 100 billion
    polyethylene plastic bags. (Only 0.6 percent of
    plastic bags are recycled.)
  • The Irish have been known to call the
    ever-present bags their national flag South
    Africans have dubbed them the national flower.

SAVE MOTHER EARTH
21
  • Think twice about taking a plastic bag if your
    purchase is small and easy to carry.
  • Keep canvas bags in your home, office, and car so
    you always have them available when you go to the
    supermarket or other stores.
  • Ask your favorite stores to stop providing bags
    for free, or to offer a discount for not using
    the bags.
  • Encourage your local politicians to introduce
    legislation taxing or banning plastic bags.

22
GOALS TO PREVENT EARTH
  • Cleanly converting nonrecyclable materials into
    energy through direct combustion or after
    conversion into secondary fuels
  • Reducing societal consumption of non-renewable
    fuels
  • Development of alternative, green, low-carbon or
    renewable energy sources

23
  • Conservation and sustainable use of scarce
    resources such as water,land, and air
  • Protection of representative or unique or
    pristine ecosystems
  • Preservation of threatened and endangered species
    extinction
  • The establishment of nature and biosphere
    reserves under various types of protection and,
    most generally, the protection of biodiversity
    and ecosystems upon which all human and other
    life on earth depends
