The passage and the lecture hold different perceptions toward the use of DDT as pesticide. The passage mentions that pesticide is hazardous for ecosystem, but the lecture argues that DDT has no correlation at all with such phenomenon. The substantial use of DDT has been claimed has harmed the population of several high food chain birds species such as bald eagle and peregrine falcon. According to the lecture, however, it has been reported that the number of bald eagle has already been in decline before the period of DDT. Another bird species, brown pelican, also reached its lowest number before the massive use of DDT. In contrast, the number of bald eagle is recorded highest during the 1960s, which is the peak use of DDT. Finally, the lecture suggests that the declining population of these species is due to hunting activity. The lecture also refuses the research mentioned certain dangerous amounts of pesticide were found inside some food chain birds’ bodies. The lecture based his view on research that shows brown pelican and peregrine falcon have no problem with their reproductive system during the DDT era. Moreover, the lecture argues that pesticide is not correlated with the eggshell weakening. The lecture claims that other factors such as oil spill, mercury poisoning and other pollutants are more responsible for this issue. Finally, the lecture disagrees with the claim saying DDT brings higher threat of cancers to humans. New research from the lecture suggests that there are no links between pesticide and human cancers. The lecture denies all the evidence presented in the passage and suggests that the use of DDT showed no correlation at all with the phenomenon. The lecture also points out that the excessive and uncontrollable use of DDT indeed might decrease its effectiveness. Further, the lecture expresses his opinion that many countries should reconsider to use DDT as pesticide again.
