effects from the widespread use of ddt and other pesticides. have you considered asking the public health service to take a closer look at this? yes, and i know that they already are. i think, particularly, of course, since ms. carson s book, but they are examining the matter. rachel carson wrote this book about pesticides called silent spring in 1962, and it talked about the long-term impacts, the concept of latency and bioaccumulation, which were all new terms. farm animals were dying with monotonous regularity because pesticides people didn t have any awareness that if a fish ate the bug that was poisoned by pesticides, that that was going to end up in our bodies. it touched a raw nerve upon the american public. the public was being asked to accept these chemicals and did not have the whole picture. so i set about to remedy the balance there.
for the people that react to the bites which is only 20% of people, they literally go crazy. i mean, they re constantly itching. they know they have bugs. they re embarrassed. you almost need some type of counseling besides termination just to get through your everyday life until the problem is gone. the staff uses cameras to record some of their most extreme cases. and there are many. if you think you re hearing more stories about bedbugs lately, you re right. you talk to anybody that s 80 years or older, they ll remember bedbugs in the united states. but they just became a cute little nursery rhyme. don t let the bedbugs bite. up until three years ago they were considered to be wiped out. they got rid of a product called ddt. it wiped out the bedbug population. since that was removed from use in america, bedbugs have become a huge part of everyday life. every apartment and high-rise
i ve just learned there s a job called mammal preparator. this is a job done by dr. anna goldman. and it s performed right here at chicago s field museum. this is the mammals prep lab. this is an example of what we do. these are are studied skins. tan skins. you re actually going to be making one of these today. why? what we re trying to is track change over time. we want to have our finger on the pulse of the environment. well, to ask, like, the screamingly obvious, why, why is it important to track populations and all of that over time? why do we care so deeply about that? so, an example, have you heard of ddt before, the that s a pesticide. it s a pesticide that was really heavily used before the mid 1980s and the reason why it

wasn t as heavily used after the mid 80s is because they found out it was one of the leading causes of the bald eagle decline and found this by looking at egg shells from the early 1900s and comparing them to egg shells in the 1980s and they found out that ddt actually resonates in these egg shells and makes them thinner. therefore, there s less survival rate of their chicks. that s an excellent answer. so these are my volunteers and interns. they give me their free time. yeah. and i put them through hell. every day. both squirrels, position of surprise. this is a female and this is a male. the cool thing about rodents is they have a bone in their penis so actually there s a bone in here. you can actually you can feel it, too, if you wanted. all right. a lot of the times with bones it kind of forces intercourse. how many species have a bone in their penis? i don t have numbers for you but there s a lot of carnivores,
