This is Part 2 of an interview with David Lewis, Ph.D. - formerly a senior-level research microbiologist at EPA-ORD. He currently serves as director of research for the Focus for Health Foundation.

Biosolids: More Harm than Good, Part 1

Dr. David Lewis, Ph.D., who was formerly a senior level research microbiologist at EPA-ORD, kindly agreed to an interview for the MOTHER EARTH NEWS blog addressing the issue of agricultural use of sewage and industrial sludge, aka – biosolids. He is one of the most prominent scientific voices in the growing opposition to biosolids land application. Dr. Lewis’ publications are frequently cited as an example of solid, unbiased scientific evidence of the danger posed by this practice.

Our Native Carnivores: A Historical Perspective

As a conservation biologist whose focus is large carnivores, I find that historical perspectives regarding our understanding of our place within Earth’s communities and the behavior that flows from those perspectives is essential to understanding our present day relationship with carnivores. In my first post, I want to take you back in history, sharing with you worldviews and the actions that expressed those views, as Europeans settled on the American continent.

Gardening Is Biology not Chemistry

Gardening is a biological process, not a chemical one. For a healthy, productive garden, help your plants cultivate the biology in the soil that will feed them.

Building Biology: Creating a Healthy Indoor Climate

There is an ideal relative humidity range for our health and that is somewhere between 35% and 55%. In modern life we have introduced many new sources of moisture into our homes. Daily showers, laundry, cooking and dishwashing tend to create concentrated bursts of humidity. Because conventional construction can tolerate very little increase in humidity without condensation/mold problems moisture from these sources must be mechanically sucked out of the home.

Buildings that Pass the Test of Time

Building Biology advises us to look for a successful history of use when choosing building materials but in our ever changing product-based building environment we seldom have the luxury of evaluating track record. This becomes quickly apparent when vetting new products for client’s homes. I recently called a major manufacturer to find out what was in a new product developed to prevent mold growth on framing lumber.

Masonry Heat: A Formula for Health, Comfort and Ecology

Although forced air is the most common form of home heat in North America it is far from ideal. This article explains why Building Biology regards the masonry heater as the ultimate heating system for health, comfort and ecology.

Tips for Finding a Healthy Building Site

If you are planning to build a healthy home your first step is to find a site that will support health and here are some helpful tips about siting

Take the First Steps: Where to Place Our Feet

An alien biologist visiting from a distant planet might look at the remarkable similarities in our physiology and conclude that chimps would live pretty much as humans do, only more simply. But there’s something definitively, well, human about us.

Concern for the Golden Toad

We’re here to confront our own biology, the essential nature that tells us to keep reproducing and expanding. If you could view the entirety of human experience from the dawn of our evolution to the present, if you could pick the human century you’d like to witness first-hand, you might choose this one.
