With some work, landscaping can be pesticide-free

Re: Green gardens

Wherever we turn, there's information about "going green," and the
real estate section of Friday's Daily Gleaner frequently addresses the
topic.

On Feb. 6 writer Joe Lamp'l is quoted as saying, "random spraying with
synthetic or even organic, non-selective insect controls when only
three per cent of insects in our gardens are actually considered pests
is anything but green! In the process, we put the other 97 per cent
neutral and beneficial insects at risk...

"About seven million birds die each year (in the U.S.) from the
residual effects of consuming insects poisoned by our backyard
pesticides... When a plant is placed in its proper growing
environment, it is more robust and vigorous without the need for
supplemental fertilizer. A healthy plant is also naturally more pest-
and disease-resistant. The result is a garden that thrives without the
need for extra chemical controls."

We could all have prettier and healthier home landscaping by using a
little extra work in combination with some intelligence, plus we'd
save money and protect the environment if we didn't use cosmetic
pesticides.

The pesticides used on crops may be responsible for the global
amphibian decline, and may be a risk to human health, according to
biologist Tyrone Hayes. Image Credit: ricephotos

“It all started with frogs. I’ve been in love with frogs since I was a
kid. But they’re excellent models for understanding things about the
environment in general, and they led me to try to understand some
important aspects of how the environment affects public health” –
Tyrone Hayes

Biologist Tyrone Hayes spoke to EarthSky’s Lindsay Patterson about the
connection between pesticides, frogs, and public health and about what
it means to speak out as a scientist.

Tyrone Hayes is professor of integrative biology at the University of
California – Berkeley.

Scientist: Environmental health is public health

Tyrone Hayes: Environmental health is public health. If you’re
altering the environment in such a way that wildlife can’t live in it
anymore, that amphibians are declining globally, for example, then
you’re creating an environment that we won’t be able to live in,
either.

That’s biologist Tyrone Hayes, of the University of California at
Berkeley. He sees a close connection between the health of frogs and
the health of humans. Hayes studies how pesticides interact with
hormones.

Tyrone Hayes: The hormones are the same. So the same chemical that
will cause a male frog to make estrogen, and become a hermaphrodite,
can cause excess estrogen production in humans, which can lead to
breast cancer.

Hayes’ research was published in the Proceedings of the National
Academy of Sciences. His study showed that these chemicals originate
in agricultural pesticides, which run off into the water supply.

Tyrone Hayes: So the frog is getting it because of swimming, drinking,
living in the water. A human would get it by being exposed as an
agriculture worker or factory worker, but also by drinking the water
in the home.

Hayes is concerned that people at high risk for exposure to chemicals
may be the least aware of the health impacts.

Tyrone Hayes: The people who are most impacted – the workers,
agricultural workers and factory workers – are less likely to have
access to information and health care. So it’s really important that
we get that information out.
