Empowered by God's grace and guided by the Holy Spirit, the Christian
life is about fulfilling the Great Commandments (Mk. 12: 28-31).
Colossians proclaims that Christ died to reconcile all of Creation to God,
showing how much God loves all of Creation: "God was pleased to have all
his fullness dwell in him, and through him to reconcile to himself all
things, whether things on earth or things in heaven, by making peace
through his blood, shed on the cross" (Col. 1: 19-20, NIV). Indeed, Christ
is not only the Reconciler of all things, He is the Creator and Sustainer
of all things as well (Col. 1: 15-18; John 1: 1-3; Heb. 1:1-4).
Unfortunately, the facts suggest that pollution and environmental
degradation are working against the reconciliation of all creation wrought
by Christ's blood.
Air Pollution
- More than one in three Americans live in areas with unhealthy air,
and in many areas it is getting worse, especially in poorer
neighborhoods. Nitrogen oxides (forms smog) have increased 11% between
1970 and 1997. Sulfur dioxide emissions (results in fine particulate
pollution or soot) increased in 1996-98 to more than 9% over 1995
levels.
- For the first time recent studies have linked air pollution to:
- the risk of dying from cancer;
- harming the blood vessels of healthy individuals;
- low birth weight, premature births, stillbirths and infant deaths;
- healthy, active children becoming 3-4 times more likely to develop
asthma;
- measurable lung damage in healthy children, which could lead to
lung disease.
- Estimates are that soot results in 15,000 premature deaths every
year.
- Smog and soot hit asthma sufferers the hardest. As air pollution has
increased, so have asthma cases - by more than 60% since 1980. Between
1985 and 1995 there was a 45.3% increase in asthma deaths. The total
estimated cost of asthma in 1993 was $12.6 billion.
- Asthma death rates for black Americans are three times that of
whites.
- One out of every three asthma victims is a child. Seven percent of
children suffer from asthma, which is the number one cause of school
absences. In 1994, this resulted in $673 million in caretaker's time
lost from work.
- Mercury contamination has forced 40 states to warn their residents
to restrict their fish consumption. Especially vulnerable are women of
childbearing age, pregnant and lactating women, children and populations
that consume large amounts of fish such as Native Americans and the
poor.
- Air pollution causes other damage to creation, including forest
damage from acid rain, ozone eutrophication (overfertilization from
nitrogen) of lakes and ponds, loss of fish and other aquatic species
from acidification, and reproductive failures caused by mercury in fish
and in birds that eat fish.
Water Pollution & Water Scarcity
- Over one billion people still lack access to safe water, and nearly
two billion lack safe sanitation. More than three million people still
die every year from avoidable water-related disease.
- Global water consumption rose sixfold between 1900 and 1995 -- more
than double the rate of population growth -- and continues to grow
rapidly as agricultural, industrial, and domestic demand increases.
- The majority of the world's population lives near and depends on
freshwater environments, with most inland cities lying adjacent to a
river or lake. In addition to being biologically rich, freshwater
systems play a vital role in the lives of many people, providing a
source of water, food, and employment. About 6 percent of the world's
fish catch, or 7 million metric tons per year, come from rivers and
lakes, as well as the bulk of the world's irrigation water.
- More than 40 percent of the world’s population lives in conditions
of water stress. This percentage is estimated to grow to almost 50
percent by 2025.
- Of the 19 countries around the world currently classified as
water-stressed, more are in Africa than in any other region.
Global Warming
- Agricultural output in many poorer countries could be significantly
reduced. An additional 80-90 million poor people could be at risk of
hunger and malnutrition later in the 21st century.
- Poorer countries are much less able to withstand the devastation
caused by extreme weather events, and climate change is likely to
increase such events. For example, global warming could increase the
number of people impacted by flooding by 20-50 million.
- Hundreds of millions of people will be at increased risk of malaria,
dengue fever, yellow fever, encephalitis, and other infectious diseases
because of global warming.
- Each of these stressors increases the likelihood of environmental
refugees and violent conflicts.
- Although the U.S. will likely have the resources to adapt to the
impacts of global warming, the poor in the U.S. will also suffer
disproportionately. For example, large cities in the U.S. may
experience, on average, several hundred extra deaths per summer.
- Up to 37% of God's land-based species could be committed to
extinction by 2050, making global warming the largest single threat to
biodiversity.

section.
Oceans
- Oceans occupy 70% of the earth's surface and are home to over 90% of
all life on earth.
- Seafood is the primary source of protein for many coastal people.
Worldwide, about 700 million persons are directly dependent upon
fisheries for food.
- Nearly one third of the world's fisheries have collapsed or are near
collapse because of overfishing. Nearly half of the world's fisheries
are being fished at their maximum level.
- Many fish are caught before they are old enough to reproduce.
- Millions of tons of "by-catch" such as sea turtles and dolphins are
hurt or killed each year, threatening their existence in some areas.
("By-catch" are creatures that are not intended to be caught but are
caught anyway.)
- Scientists hope to identify many of the estimated million-plus
species of life in the oceans (only a small fraction of which have been
identified to date) through a comprehensive global study called the
Census of Marine Life. This includes the expected identification of at
least 5,000 new species of fish.
- Sewage is the largest source of contamination by volume of God's
oceans.
- Worldwide approximately 250 million people become sick each year
after eating contaminated fish or bathing or swimming in contaminated
coastal waters. Even in coastal waters deemed swimmable, 5% of adults
worldwide will become sick after a single swim.
- Air pollution from vehicles and industry, as it falls from the sky,
contributes approximately half of the nitrogen pollution in oceans, and
a significant portion of the mercury pollution. As developing countries
industrialize, atmospheric pollution is expected to increase.
- Nitrogen levels in oceans are exacerbated by the widespread loss of
natural interceptors such as coastal wetlands, coral reefs, and mangrove
forests. In the United States 200,000 acres of coastal wetlands and
estuaries are lost each year.
- So-called "dead zones," or oxygen-depleted areas resulting from
nitrogen and other pollution, are increasing in frequency, intensity,
and geographic distribution worldwide. In the United States each year, a
dead zone the size of Massachusetts is created in the Gulf of Mexico.
This year's dead zone in the Chesapeake Bay was the largest in the Bay's
history. Dead zones now occur in almost every coastal state.
- Two-thirds of U.S. estuaries and bays are either moderately or
severely degraded by pollution.
- Each year garbage dumped in God's oceans kills large numbers of sea
birds, sea turtles, and marine mammals as they eat it or become
entangled in it.
- Sprawl anywhere - not just near coastal areas - causes significant
damage to God's oceans. Paved surfaces cause oil, grease, and other
toxic pollutants to reach coastal waters. In the United States, every
eight months nearly 11 million gallons of oil run off our streets and
driveways into God's streams, rivers, and oceans - the equivalent of the
Exxon Valdez oil spill. A one-acre parking lot produces about 16 times
the volume of runoff that would come from a one-acre meadow.
- Coastal counties in the United States, which comprise just 17% of
U.S. land, are home to more than half of the U.S. population. Sprawl
development is consuming land at least five times as fast as population
growth in many coastal areas.
- Worldwide nearly 40% of the world's population lives near a coast -
more people than inhabited the earth in 1950.
- The poor living in coastal communities - the least able to deal with
the multiple harmful consequences of global warming - will be the
hardest hit. The consequences will be dire.
- Changes in water temperatures and other consequences of global
warming (e.g. changes in salinity, nutrients, sea level) have a profound
effect upon marine species. For example, water temperature can have a
direct effect on spawning and survival of larvae and juveniles as well
as on fish growth.
- Marine mammals such as polar bears are "the canary in the coal mine"
when it comes to changes in ocean environments. For polar bears,
extended ice-free seasons in the Arctic due to global warming could
reduce access to seals and lead to deaths from starvation.
- Increases in atmospheric temperature from global warming may slow or
shut down the Atlantic's Gulf Stream, causing reductions in sea-surface
and air temperatures over the North Atlantic and northern Europe.
- Coral reefs harbor more than 25% of all known marine fish, as well
as a total species diversity containing more phyla than rainforests.
- Current estimates are that 10 percent of all coral reefs are
degraded beyond recovery. Thirty percent are in critical condition and
may die within 10 to 20 years. If current pressures continue unabated,
60 percent of the world's coral reefs may die completely by 2050.
God’s Other Creatures(see also the EEN
booklet on Endangered Creatures)
- Worldwide, at least 15,589 species face extinction. However, this is
certainly an underestimate, because it is based on assessments of only
3% of the world's 1.9 million species that have been described. A
majority of the world's species have not been described.
- Although estimates vary greatly, current extinction rates are at
least one hundred to a thousand times higher than background, or
"natural" rates.
- There are major gaps in our knowledge of the status of threatened
species. We know little about marine and freshwater systems, or many
species-rich habitats (such as tropical forests or the ocean depths), or
species-rich groups such as invertebrates, plants, and fungi (which
together comprise the vast majority of species).
- Global trends indicate increases in the number and rate of
extinctions of described species, and the main causes of extinction
(such as habitat loss and exploitation) are increasing.
- One in eight birds and one in four mammals are known to be in
jeopardy.
- One in three amphibians and almost half of all freshwater turtles
are threatened.
- The first complete assessment of amphibians (i.e., frogs, toads,
salamanders) reveals they are likely to be the most threatened
vertebrates, with at least 1 in 5 species in the Critically Endangered
or Endangered categories.
- Over one in five (21%) of the world's plant species may be
threatened with extinction.
- Over one-third of all assessed North American invertebrate species
are threatened with extinction. A current study indicates that the
actual number of all threatened invertebrate species in North America
may be five times this number.
- Most threatened bird, mammal, and amphibian species are located on
tropical continents—Central and South America, Africa south of the
Sahara, and tropical South and Southeast Asia. These regions contain the
tropical broadleaf forests, which are believed to harbor the majority of
the earth's living terrestrial and freshwater species.
- Countries that have the highest numbers of threatened species tend
to be the least able to invest significant resources into conservation
because they have relatively low gross national income. These include
Brazil, Cameroon, China, Colombia, Ecuador, India, Indonesia,
Madagascar, Peru, and the Philippines.
- A new survey of the world's oceans has confirmed that 90% of large
predatory fish (such as sharks) in the world have been wiped out in the
past 50 years because of commercial fishing.
- Industrialized fisheries typically reduced targeted fish populations
by four-fifths within 15 years.
- Forest cover has been reduced by more than 20 percent worldwide,
with some forest ecosystems, such as the dry tropical forests of Central
America, virtually gone.
- Wetlands areas have shrunk by about half; and grasslands have been
reduced by more than 90 percent in some areas.
- Insects comprise more than half of the world's species. Strong
evidence suggests that huge numbers of insect species are disappearing,
as are other species that depend upon them. Researchers in Britain
discovered that 71% of butterfly species have declined or disappeared
over the past 20 years, as well as 54% of birds. The past 40 years has
seen declines in 28% of plants studied.
- A study published in the January 04 issue of Nature indicated
that 15-37% of known land-based species could become "committed to
extinction" by 2050 due to global warming.
- Humans have been the main cause of extinction and continue to be the
principle threat to species at risk of extinction.
- Habitat loss, introduced species, over-exploitation, and pollution
are the main threats, with human-induced climate change becoming an
increasingly significant threat to species.
