TEDTalks Discussion

Talk1: John Foley: The Other Inconvenient Truth

DiscussionQuestion: Were you aware of the huge environmental impact thatagriculture has on the environment? Do you think that we can stillfeed a population of 9 billion people without farming more land? What do you think of his solution (terraculture)?

Iwas aware of the significant impact that agriculture has on theenvironmental but I had not had considered the huge impact asdiscussed in the ted talk. After the talk, I have a more extensiveand comprehensive view of the impact of agriculture. I think we canfeed the population of 9 million people through the adoption ofmodern farming methods such as irrigation and the terraculturesuggested by the speaker. About the solution of terraculture, I thinkit is a good revolutionary method of farming, but requires furtherresearch and education to farmers.

Talk2: Marla Spivak: Why bees are disappearing

Discussionquestion: Had you heard of CCD (Colony Collapse Disorder) before this talk? Were you aware of the importance of bees as pollinators? Do youthink, given our current agricultural practices, that honeybees canrebound from CCD?

Tobe honest, I have never heard about Colony Collapse Disorder (CCD)before this talk. However, I was fully aware of the importance of thebees as pollinators in the mutual process of nature that leavesflowers fertilized and bees earning their honey. The talk gave me ahigher insight into the relationship between plants and animals,especially the bees as they play a significant role in ensuring foodproduction takes place. I think that bees cannot rebound from CCDgiven our current agricultural practices. This is because our farmingpractices like the use of pesticides contributes to the developmentof the CCD on bees.

Talk3: Penelope Jagessar and Tyrone Hayes: The Toxic Baby

Discussionquestion: The EPA decided to approve the continued use of Atrazine, even afterits effects on frogs were shown? Why do you think they did this? What other factors (besides “science”) may have played a role intheir decision? Do you think Atrazine should be banned? Why or whynot? Iexpect to see 2-3 sentences of discussion!

TheEPA approved the use of Atrazine despite the effects on frogs becauseof the consideration of other factors rather than safety concerns.They seem to have considered its effectiveness in killing weeds as amajor factor. They also considered the lack of more information onthe specific effects of Atrazine on mammals. I think Atrazine shouldbe banned and replaced with another pesticide that does not havesafety risks.

FinalQuestion:Discuss some final thoughts you have after watching these talks. Youmight discuss which talk taught you the most, or made you think themost, or that you found the most interesting You might talk aboutsome things you learned that you did not know before. You could alsotalk about questions you now have after watching these talks.

Watchingthese talks was very insightful and educational. I was able tounderstand environmental issues more deeply and from the perspectiveof another person. The talk on bees taught me most about theenvironmental phenomenon we take for granted, and are the mostimportant natural processes.
