The black robin is a small bird native to the islands of New Zealand. Several decades ago, black robins almost died out. Although the future of the species remains uncertain, efforts to save the black robin from extinction have been remarkably successful. Many observers previously believed these conservation efforts would fail. Indeed, scientists attempting to save the black robin faced several significant challenges.
First, black robins lack defenses against predators. Although black robins can fly, they do not fly particularly well, and they have no natural fear of predators. The black robin species evolved on isolated islands with very few or no predators and therefore did not develop defensive abilities. When humans later introduced mammalian predators, such as cats, these predators quickly eliminated most of the black robins, and the remaining birds seemed unlikely to survive.
Second, the highly specialized diet of black robins was also problematic. They feed on spiders, worms, and some insects. Because the population of these food sources varies naturally throughout the year, black robins had difficulty competing with numerous other species for the available food. So when they could not find enough food to feed themselves and their young, black robins became malnourished. This lack of nutrition weakened the birds, making them more likely to die.
Finally, black robins’ low rate of reproduction was another obstacle. Black robins normally reproduce only once per year, laying very few eggs. Even worse, the black robin population was so low at one point that there was only one fertile female left alive. This meant that the black robin population could increase only by a few birds at most each year. Even if scientists could resolve the birds’ other problems, the black robin’s low reproductive rate seemed likely to slow or even prevent their recovery.

Professor：
To continue our discussion of the health benefits of good nutrition, I’d like you to consider the broader topic of eating habits-not just what people eat and drink, but how often, how much, and when. Those who want to improve their health often begin by changing some kind of eating habit. This includes a wide range of behavior. What is one poor eating habit that would be important for most people to change, and why?
Kelly:
If people could start with one change to improve their eating habits, it would be to eat a better breakfast. Most people are so rushed in the morning that they don’t take the time to sit down and eat a balanced meal. A good breakfast gives you more energy all day and keeps you from eating too much later on.
Andrew:
I think most people don’t bother to learn much about the food that they eat. This ignorance is a kind of bad eating habit. It can be burdensome, but you should try to read every food package label. The more you can learn about what you’re putting in your body, the more likely you’ll be to make good decisions.
