Leading biologists, climate scientists, and environmental watchdogs
all agree—humans’ own impact on the environment is without a doubt the
number one cause of species loss.
Habitat destruction, fragmentation, and modification caused by
human-led activities (i.e., industrial and residential development,
logging, crop farming, livestock grazing, mining, road and dam building,
and pesticide use) have taken an extreme toll on threatened and
endangered wildlife populations at an alarming rate. With breeding
grounds devastated and access to food and other resources diminishing,
it’s no wonder that we’ve seen such a decline in species diversity.
Yet we still see—in the press, in non-peer-reviewed publications, and
in public policy—people blaming wildlife decline on cats. Sidestepping
the issue of human destruction to focus on trivial but sensational
issues, such as the so-called ‘cat versus bird’ debate, only diverts
attention away from the enormous and far more dangerous impact of
humans.
The Danger of Development
A 2010 report from the scientific fellowship
The Royal Society
concludes that “never before has a single species driven such profound
changes to the habitats, composition and climate of the planet…”
1
The report also ominously states that “there are very strong
indications that the current rate of species extinctions far exceeds
anything in the fossil record.” The message is clear: humans are having
an unprecedented impact on the planet—and species are going extinct at
an unprecedented rate.
In America alone, the fast-growing population and even faster
development of land is wiping out habitats like never before. Between
1990 and 2000, the US population grew by 33 million people, the greatest
increase the country has ever seen. Population growth from 2000 to 2010 added another 27 million people.
2 Experts predict that this
rapid population growth will continue, adding another 23 million people
each decade for the next 30 years.
3 That’s 69 million people more in the United States.
Worse, America’s demand for resources is outpacing our already
troublesome population growth. According to the National Resources
Defense Council (NRDC) almost one-sixth of the land developed over the
entire history of our country occurred in a ten-year period, from 1982
to 1992.
4 And while our population grew by less than 50% from
1960 to 1990, the amount of developed land in all US metropolitan areas
more than doubled.
5 Researchers at Brookings Institution
predict that by the year 2030, half of the buildings in which we live,
work, and shop will have been built after the year 2000.
6
Our rapid expansion—and even faster use of resources—has destroyed or
disconnected vital wildlife habitat. Since Europeans first settled the
continent, 27 ecosystem types have already declined by as much as 98%.
7
Most of the species who call these ecosystems home are not adaptable to
the human landscape that is left them. If our current development and
population growth continue unchecked, the serious loss of animal species
will continue for decades to come—unless we do something now to address
the human threat.
The Human Impact on Birds
Opponents of Trap-Neuter-Return, the sound and effective approach for
feral cat colonies, often blame cats for bird species decline, but
humans are by far the biggest threat to bird species. The exponential
population growth and vast expansion discussed above has left little
land untouched by human development, modification, fragmentation, and
pollution.
And so millions of bird deaths occur every year due to human
activities—nearly 100 million from colliding with windows, 80 million
from collisions with automobiles, and about 70 million from exposure to
pesticides.
8 Our own government tracks how many animals (birds included) it kills—over 4 million in 2009 alone.
9
In a 2000 report by the World Conservation Union surveying 1,173
threatened bird species, habitat loss was the most important threat,
affecting 83% of the bird species sampled. As the World Watch Institute
put it (emphasis added):
"…[P]eople have always modified natural landscapes in the course of
finding food, obtaining shelter, and meeting other requirements of daily
life. What makes present-day human alteration of habitat the number-one
problem for birds and other creatures is its
unprecedented scale and intensity.
10"
Cats are a Natural Part of the Landscape
Cats have always been part of the natural environment—
they have lived outdoors for over 10,000 years. While they have adapted to the changes people brought about in the environment,
their biological instincts and interactions with their surroundings have not changed.
What
has changed in the last 10,000 years is how people have
impacted the environment. Our unrestrained use of natural resources has
damaged the crucial habitats and resources species need to survive.
Instead of pointing a finger at cats, we must take a hard look at
what we can do to change the way we impact our world and the animals we
share it with. We have the ability to conserve our natural places,
minimize our impact on wildlife habitat, and build responsibly. To make a
difference, we must align our attention and resources to offset the
biggest offender in habitat destruction and species decline—ourselves.
NOTE: We support feeding/watering feral cats, there are often local resources to provide humane traps and free, or low cost, spay neuter services. We're horrified when we hear people "parrot" off the absurdly false figures of the billions of US birds killed by feral & house cats.
That's simply is not true.
We live rurally and co habitat nicely with Ferals. In the last 20 years I may have seen a couple of birds that could be attributed to cat kills. Although I did not see the cat kill the bird, just the remains, the bird could have died from other causes. I know that cats reduce the mouse population substantially, for which I'm grateful.
When people spout off the ridiculous kill figures attributed to cats, please help gently educate them.
Don't see mice? Thank a cat!
