The dodo was a large flightless bird native to the island of Mauritius in the Indian Ocean. Until it was colonized by the Dutch in the early 1600s, Mauritius had no human settlement. Within a hundred years of the arrival of the Dutch settlers, the dodo was extinct. The evidence, though circumstantial, suggests that it was the impact of humans that brought about the bird’s extinction.
First, it needs to be kept in mind that the dodo was not only flightless, it was defenseless. The bird had not evolved behaviors of escape, hiding, or attack because it had no predators. So when predators did arrive in the form of humans, the dodo would have been extremely easy prey. And the dodo would have been a ready source of meat for humans—virtually the only one on an island that had no indigenous mammals other than bats. Given these facts, it would not have taken long to hunt the dodo to the verge of extinction.
Second, the dodo was a forest bird whose habitat was largely destroyed by the invading humans. Once the Dutch settled the island, extensive areas of forest were cleared for farming. With the destruction of the forests, the dodo would have been deprived of both food and shelter, making its extinction the inevitable conclusion for a population already greatly reduced by hunting.
Finally, archaeological evidence shows that the dodo had lived on the island for thousands of years before humans arrived. It is clear, then, that Mauritius offered a favorable and stable environment for the dodo and that the species would have continued to survive on the island had things continued as they had been. But that was not to be. Humans arrived and within a few decades the dodo was extinct.

Last week, we started talking about decisions that university administrators have to make regarding spending. They often need to decide how to allocate their funds, including renovating existing facilities, offering new amenities, and so on. For example, a university could spend money to upgrade a sports stadium, build a new performing arts center, or do a variety of other things. What is the most important thing universities should consider when making decisions regarding spending?

I think the university should get input from its students on what improvement they want to see on their campus. In fact, they make up the majority of people who will be attending sporting events at a renovated stadium or live musical theater performances in a new performing arts center.

The university needs to consider how much revenue amenities would generate. Building a new facility or renovating an old one would both be very costly, so administrators need to think about which option would bring in the most money in the future. Generating revenue would allow the university to fund other improvements to the campus in the future.
