1. Biodiversity Introduction

“In the next few Science Insights we’ll explore the meaning and importance of biodiversity—literally “life variety”.  We’ll put it into context in Tasmania’s agricultural as well as world heritage environments, and examine ways to preserve and enhance it.”

2. Biodiversity and Nutrition

“…mamas teach their babies where to find what they need, and how to know when to eat which plants.”

3. Biodiversity and Weeds

“In the world of Dr. Seuss, weeds would be plain-belly sneetches. Their close relatives, the star-belly sneetches, would be the rest of the plants—the ones we think we want around.”

“. . . grazing in farmland and bush is, like chocolate and carbon dioxide, a good thing in moderation.”
