The lecture argues that the advantages of planting vegetation on rooftops are markedly exaggerated. This contradicts to the point presented in the passage that living roofs are highly advantageous.
First of all, the lecturer portrays skepticism toward the explanation of the reading that states Green roofs solves the shortage of city parks. He supports his opinion by explaining that although the total area of city parks increase, due to the lack of access with the city park itself, he thinks living roofs are worthless.
In addition, the lecturer disagrees to the explanation of the reading passage which talks about the provision of beautiful sights from green roofs. Because people generally walks the sidewalk and does not have a chance to watch the rooftop, the lecturer disproves the statement of the reading.
Thirdly, the lecturer casts doubt on the opinion of the reading. He states that although insulation-related costs may drop, as presented in the reading, he strongly states that additional costs including installation and maintenance costs far outweigh the advantages.
