NOTE FROM TED: While plastic pollution has been identified as a public health and safety concern, the relationship between plastics and specific health conditions discussed in this talk warrants further scientific investigation. To read more about this ongoing field of study, current debates, and research challenges, see the footnotes below. TEDx events are independently organized by volunteers. The guidelines we give TEDx organizers are described in more detail here: http://storage.ted.com/tedx/manuals/tedx_content_guidelines.pdfFootnotes:
3:27 Clarification: As there are many chemicals involved in plastic production and use, it is difficult to link specific health issues with specific chemicals and plastics, and especially difficult to estimate the number of cases they contribute to. Current hypotheses suggest that environmental exposures are not typically the sole cause of disease, but several chemicals found in many plastic materials might contribute to or worsen existing conditions. Calculations and estimations can vary, but the sources below provide context for the numbers cited in this talk:
This paper estimates that exposure to the phthalate DEHP may contribute to approximately 8.74% of global preterm births. Read more about how this range was calculated here: https://pmc.ncbi.nlm.nih.gov/articles/PMC13133540/#sec4
Estimates on the relationship between cardiovascular mortality and chemicals found in plastic materials in the United States: https://pmc.ncbi.nlm.nih.gov/articles/PMC10783259/
Additional estimates on the relationship between phthalates and various cancers, hypothyroidism, endometriosis, and infertility are variable. This table explains how they were calculated in the paper linked above: https://pmc.ncbi.nlm.nih.gov/articles/PMC10783259/#abstract1:~:text=Table%208,-%2E
5:14 Clarification: As the speaker states, there is an important distinction between (1) chemicals found in plastic products (like PFAS, BPA, and phthalates) and (2) microplastics and nanoplastics which are small fragments or particles of broken-down plastic. For example, several research papers, such as those linked above, present an association between phthalate exposure and adverse health effects at a population level. However, there remains debate and challenges to studying how exactly microplastics interact at the individual level.

A pediatrician reveals how plastics may harm human health—and why scientists who speak up often face doubt, backlash, and attacks from powerful interests. Dr. Leonardo Trasande is the Jim G. Hendrick, M.D. Professor of Pediatrics in the Department of Pediatrics and the Director of the NYU Center for the Investigation of Environmental Hazards. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx Receive SMS online on sms24.me
TubeReader video aggregator is a website that collects and organizes online videos from the YouTube source. Video aggregation is done for different purposes, and TubeReader take different approaches to achieve their purpose.
Our try to collect videos of high quality or interest for visitors to view; the collection may be made by editors or may be based on community votes.
Another method is to base the collection on those videos most viewed, either at the aggregator site or at various popular video hosting sites.
TubeReader site exists to allow users to collect their own sets of videos, for personal use as well as for browsing and viewing by others; TubeReader can develop online communities around video sharing.

What is YouTube?
YouTube is a free video sharing website that makes it easy to watch online videos. You can even create and upload your own videos to share with others. Originally created in 2005, YouTube is now one of the most popular sites on the Web, with visitors watching around 6 billion hours of video every month.
