AT TYPICAL HIGHWAY SPEEDS,it may be no more than a sudden, blurry impression of red, quickly and thankfully left behind in mind and space--a bump on the road, probably a badly mangled small body you and other drivers strive to avoid--but the jarring occurrence is almost inevitable these days. It's the sight of an animal killed on the road. The American highway devours animals' lives at an astonishing rate--twelve victims a second, up to a million animals a day, perhaps more than 300 million casualties a year. Nobody knows the actual precise figure, but most observers agree it is huge.*
In magnitude, it's an animal holocaust surpassed only by the hell of factory farming. Indeed, the carnage is so unrelenting that by the time you finish reading this column, more than 6,500 additional animals will have succumbed in the U.S. to lethal encounters with fast-moving vehicles and uncaring or incompetent drivers. Compared to this victimization, human casualties, tragic as they are--50,000 a year--pale into insignificance. For every human fatality, 80,000 animals die on the road. And the slaughter is likely to get worse: Congress has just raised the speed limit on some rural highways, where many animal killings occur, to 65 miIes per hour.
Roadkill figures are very high in the US, but the carnage is global. As the accompanying images illustrate, from North America to Australia, Paraguay, Singapore, India, Africa, Thailand, China and Europe, no country or continent is safe for wildlife in the proximity of roads.

Yet the problem is not only a question of speed limits and irrepressible highway and urban proliferation. Its roots go much deeper, to the cultural and economic origins of the Great American Highway, and our unbroken romance with the private automobile.
Business-minded America has always been a nation in a hurry, impatient with delays and intolerant of any obstacles which might hamper mobility or profit. In no other modern industrial nation has individualism cut so deep or produced more disturbing consequences. Sociologist Philip Slater wasn't too far off the mark when he noted in his book The Pursuit of Loneliness,
"Americans attempt to minimize, circumvent, or deny the interdependence upon which all human societies are based ... We seek a private house, a private means of transportation, a private garden, a private laundry, self-service stores, and do-it-yourself skills of every kind. An enormous technology seems to have set itself the task of making it unnecessary for one human being ever to ask anything of another in the course of going about his daily business ... We seek more and more privacy, and feel more and more alienated and lonely when we get it."

Roadkills are symptomatic of humanity's dismal priorities when it comes to animals
For a nation in love with the idea of privacy the automobile was the logical choice, and it seemed an affordable choice, too, at a time when oil was thought inexhaustible and gas-engine pollution was not seen to represent the threat of climate change oblivion.
The final push toward highway proliferation came in the wake of World War 2, when the massive exodus of the new, affluent middle class to suburbs without adequate public transportation triggered an aggressive program of road construction all over the United States. The newly minted Cold War also played a part: An ambitious highway construction program received an added boost from the Eisenhower administration as it made preparations for the rapid deployment of war materials and military units across the US (a concept supposedly pioneered by Hitler, who envisioned the autobahn as a network of roads to complement trains in the deployment of armor units). In the 1950s, no one could foresee the actual consequences of such actions.

These developments pleased (but scarcely surprised) the oil and auto industries. Hardly a disinterested observer, the auto industry, in particular, led by General Motors, had long pressed the American government for the dismantlement of most forms of public transportation. The switch eventually doomed numerous rail and bus systems across the nation; by the late '40s the car and its inseparable sidekick, the highway, had won. From that point on, the yearly advance of the asphalt ribbons became a fact of life in the young, car-addicted republic.
The Search for Solutions--Breaking Loose from Carmania and the Privatizing Urge
The problem of the omnipresent highway is as much a political as a technical one. Without relaxing the mesmerizing influence that runaway individualism and the powerful auto lobby exert on national policy, without an energetic campaign of public education, the chances for real gains are remote or nonexistent.

Consider what may have to be done:
A new national mass transit and freight system. Whatever else is done, it's indisputable that a shift back to urban, suburban and interstate railway and bus systems, especially for commuting and freight purposes, would greatly reduce highway congestion, pollution and fatalities. A variety of organizations are now advocating increased federal and state funding for improved public transportation. Whenever possible, animal advocates should support (or suggest) such initiatives.

Urban redesign and better utilization of land resources.
In the not-too-distant past most people lived and worked in the same community. Traveling great distances to the workplace on a daily basis was unthinkable. Modem industry gradually broke up the former integration of working and living spaces, but the 21st Century may yet see a return of the "integrated" lifeplace. Because of economic criteria, a higher ethical awareness, and the possibilities afforded by the wholly "computerized environment," (telecommuting and the "digital office"), urban planners are now better positioned to design more efficient housing and more self-contained communities. By reducing human pressure on habitats, housing and industrial design geared to maximizing available space may play a crucial role in helping the environment and the animals.
Improvements in highway and automobile design. Ideally, all new highways should incorporate animal welfare and habitat-sharing standards as legitimate design questions. A great deal of truly creative research needs to be done in this field, with ethologists providing data on the habits and characteristics of numerous species. The object, of course, would be to deter and interdict random animal access to the roads, while providing safe crossings at adequate intervals. This might prevent the current "fracturing" of animal habitats, while still allowing the animals to cross roads to gather food, find shelter, locate mates, rejoin their offspring or simply get home. Scent deterrents, human-inaudible sounds, electric-eye fencing, overpasses and underpasses ("animal bridges") are some of the possible techniques. The perfect solution is still far off, but the U.S. must join the search for answers, and there are exciting industries waiting to be born. Naturally, all such innovations would have to be incorporated in both new and existing roads.
Koalas, a fragile species, are also subject to high rates of road victimisation.
To complement all the above, the gas-engine vehicle itself might have to be considerably enhanced and probably redesigned. At present there's an acute need for improved nighttime visibility (i.e., non-glare high beams) and for better communications between drivers, especially new signalling devices to warn oncoming traffic when an animal or another emergency is spotted a few hundred feet ahead. In addition, on-board animal deterrence and driver-alert systems based on radar or infrared technologies might provide the crucial edge to avoid most fatal collisions.

But technical innovations alone can't beat the odds. The US., which of all modem industrial nations has the least stringent licensing requirements for drivers, should be persuaded to institute new, federally-sponsored "driver enhancement" programs to teach all drivers including so-called professionals--the best ways to react under all sorts of weather and animal emergencies. (In this area, television, Internet-borne materials, and regular videotapes could prove invaluable.)
Roadkills needn't be accepted as the "inevitable" price of progress. New types of highways—judiciously built, including the new "smart highway" concept—coupled with urban and automobile improvements can go a long way to relieve human pressures on the animal world. In adopting these measures, Americans will not only regain some of their lost fellowship; in so doing they'll also hasten the day when the freedom to drive someplace will not automatically imply the high probability of depriving countless innocent animals of their lives.

ADDENDUM
A recent study showed that insects, too, are prone to a very high risk of roadkill incidence.[3] Research showed interesting patterns in insect/butterfly road kills in relation to vehicle density. Although the insect population is also at risk, much of the attention goes to bigger, more charismatic animals. Other animals with smaller biomass, like avian species, are also caught in vehicular collisions. The estimates vary greatly (attesting to the fact we need better studies): 350,000 to 27 million birds are estimated to be killed on European roads each year.[4]
Breakdown by species
In 1993, 25 schools throughout New England participated in a roadkill study involving 1,923 animal deaths. By category, the fatalities were:[5]

- 81% mammals
- 15% birds
- 3% reptiles and amphibians
- 1% indiscernible
Extrapolating these data nationwide, Merritt Clifton, editor of Animal People Newspaper estimated that the following animals are being killed by motor vehicles in the United States annually:[6]
- 41 million squirrels
- 26 million cats
- 22 million rats
- 19 million opossums
- 15 million raccoons
- 6 million dogs
- 350,000 deer
This study may not have considered differences in observability among taxa (i.e. dead raccoons are easier to see than dead frogs[citation needed]), and has not been published in peer-reviewed scientific literature.

The wheels of business and human food compulsions are implacable and totally lacking in compassion. This is a downed cow, badly hurt, but still being dragged to slaughter. Click on this image to fully appreciate this horror repeated millions of times every day around the world. With plentiful non-animal meat substitutes that fool the palate, there is no longer reason for this senseless suffering. Meat consumption is a serious ecoanimal crime. The tyranny of the palate must be broken. Please consider changing your habits in this regard.
