But first, we are killing
other animals. The recent news that the last
male northern white rhinoceros died in Kenya has spread around the world. Who
cares? For most people, the rhino is a freakish zoo animal, interesting but
unimportant. After white hunters killed most of the rhinos in Africa and
southern Asia, the remaining herds have been decimated
by poachers seeking their horns, supposedly useful as medicine. At least 6000
rhinos have been killed in Africa over the past ten years.
Extinction is a natural
process – witness the dinosaurs. Scientists say that one to five species die
off naturally every year. But the Center for Biological Diversity estimates
that we are losing dozens
of species every day, thousands of times the natural rate. At that pace, by
2050, a third to a half of all species could be gone.
Our attention is attracted by
the extinction of mammals, especially primates most closely related to humans.
The International Union for Conservation of
Nature, a global authority on conserving the natural world, estimates that
half of the earth’s primate species are at risk of extinction. Of the 5500
known species of mammals, one-fifth
are endangered, especially some marine mammals, including whales and
porpoises.
The Intergovernmental
Science-Policy Platform on Biodiversity and Ecosystem Services has a long name
and an important function. It connects the world’s governments to offer advice
on the state of biodiversity. Its conference last week brought together
scientists from 100 countries who have been studying the decline of
biodiversity and what to do about it. Their reports are frightening.
Since Europeans arrived in
America, about one-third
of plant and animal species in the Western hemisphere have become extinct.
Another quarter are at risk of extinction. Elsa Nickel from the German
Environmental Ministry said,
“Biological diversity is no longer an exotic idea for environmental activists,
who want to save a few orangutans in the rain forest.”
The causes are well known:
deforestation, water and air pollution, unsustainable consumption of resources,
climate change, decline of coral reefs. Here’s another – convenience. Our
advanced society conveniently removes the garbage that our wasteful lives
produce and sends it out of our sight. Where does it go? A lot ends up in the
biggest garbage dump on earth, the Great Pacific Garbage Patch.
Ocean researchers have been
aware of a giant
floating garbage dump in the Pacific Ocean for a long time. Recently they
realized it was much bigger than they had thought – an estimated 87,000 tons of
floating debris, covering an area four times the size of California. Half of
the mass of human junk in the Great Pacific Garbage Patch is fishing
nets. Plastics made up about three-quarters of the diet of sea turtles caught
near the Patch. “It’s like a ticking time bomb,” said Joost Dubois, a spokesman
for the Ocean Cleanup Foundation.
Plastic has been replacing
natural materials, which disappear harmlessly into the environment. Fishing
nets are increasingly made of plastic because they last longer, which becomes a
danger when they are abandoned in the water. More plastic was produced in the
last ten years than ever before, about 320 million tons a year. Most of that
mass eventually finds its way into landfill or the oceans. Better living
through chemistry? Only temporarily.
When I was in graduate school
in 1973, a friend and I distracted ourselves from studying by watching the film
“Soylent Green”. The
melodramatic plot centered on the attempt by a future policeman in 2022, played
by Charlton Heston, to solve a murder in New York City, when pollution and
global warming have led to food rationing. Surviving several assassination
attempts, Heston figures out that the Soylent Green wafers that people are
eating are made from human bodies, the only source of protein abundant enough
to feed an overpopulated world.
The human race will survive
well beyond 2022, but for how long? What will the earth be like 50 years from
now, when my children are in their 80s? Despite remarkable advances in science,
the earth is much worse off than it was 50 years ago – much more pollution,
many more threatened species, disappearing forests and jungles.
Half-hearted efforts at
recycling are not enough. Without significant changes in the way we interact
with our natural environment, the human future looks frightening. The
unwillingness of many in our society to confront the facts of shrinking
biodiversity represents cowardice, selfishness, and stupidity. Among 18
countries surveyed by National Geographic, Americans
are the most disbelieving about the science of climate change.
We have to change what we
eat, how we travel, how we farm, how we consume. That’s especially true for
Americans. We stand out in the world for our profligate consumption of
resources and our production of garbage. With 5% of the world’s population, we
use one quarter of the world’s coal and oil, and we create half
of the world’s solid waste.
The only way to figure out
what to do is to follow the lead of scientists. They have done their job of
warning us that we are ruining our own future. Now we have to stop killing our
planet and killing ourselves.
