Summarize the points made in the lecture, being sure to explain how they cast doubt on the specific solutions proposed in the reading passage.

Glass is one of the most important materials for modern architecture buildings. Glass can be designed in different ways. The usual types of glass that are utilized in buildings may be dangerous for birds. The reason is they can not distinguish between glass and open air, and they usually detect the glass as a part of the sky. As a result, to solve this problem, the passage gives three possible solutions, but they all seem useless, according to the lecture. The first solution that the passage represents is "One-Way Glass." The method is to change the regular glass with one-way glass, which is transparent in only one direction. However, the lecturer points out that this can not prevent birds from being harmed because the one-way glass still works as a mirror and reflects the sky. The second solution, called "Colorful Designs," is about painting colorful lines or different designs on regular window glass in a way that people would be able to see through the openings in the design, and birds can detect the stripes as barriers. This idea is rejected by the lecturer. The lecturer mentions that the birds see the stripes as holes, and they are still trying to fly through the glass. The third solution that is also rejected by the lecturer is "Magnetic Field." For using this method, architects should create an artificial magnetic field that emits magnetic signals by powerful electromagnets to guide birds away from buildings. The reason that this method is not successful is birds would not be used their natural ability to navigate with magnetic fields for short distances. Overall, I believe the lecturer mentions rational explanations for rejecting all three solutions. Of course, harming birds by colliding with glass is a major and crucial problem that should be solved.
