1
Coming up on 60 Minutes, a world choked by plastic.
2
We're the guinea pigs for thousands of new chemicals.
3
New data reveal shocking details.
4
We've got plastic in our brains.
5
About just what it's doing to you and me.
6
So am I putting my kids in danger?
7
That's the million dollar question, isn't it?
8
That's next on 60 Minutes.
9
Convenient, durable and cheap.
10
Plastic products are an everyday part of everyone's lives.
11
But for all of the benefits, it's becoming increasingly obvious the planet is paying a price.
12
We are now living in a world choked by plastic.
13
Most of us are aware the oceans are awash with the stuff and wildlife is dying because of it.
14
But it's now time to also consider the impact and harm plastic is having on humans.
15
As you'll see, it's truly shocking how it's invading our bodies.
16
Welcome to my home.
17
Money!
18
Come on in.
19
There's probably no such thing as a typical Australian house, but mine is just like many others.
20
Three school -aged kids, a hard -working husband and father topped off with a sometimes too inquisitive wife and mother, me.
21
There's no question our home is full of love.
22
But what I'm not so sure about is if it's also full of danger from plastics.
23
How are you, Scott?
24
Good, how are you?
25
I'm very well, thank you.
26
Come on in.
27
Thank you.
28
Three weeks ago, Eco -toxicologist, Dr Scott Wilson, came in to try and answer that question.
29
The scientists started by strategically placing petri dishes in different rooms to collect dust.
30
Well, this is a house of chaos with three young kids.
31
What are you expecting to find?
32
You're going to have products that are releasing microplastics either into your food
33
or into the air that you're then breathing or your kids are breathing.
34
Plastic is so prevalent, you can't ever remove it.
35
My husband Luke has been worried about plastic for a while, and now so am I.
36
How does our house measure up?
37
Is it bad news?
38
Hold your horses, hold your horses.
39
A little later, the full results of that experiment in my home.
40
But first, facing the uncomfortable truth about how ubiquitous plastics are in our lives.
41
Few of us think about it, but we're eating, drinking and, yes, breathing them in enormous quantities.
42
Sure, we might be worried about the damage they cause to the world's oceans and wildlife.
43
But what about the threat they pose to humans?
44
You and me.
45
I think if people realised how much plastic was going through their bodies, they would actually feel a bit squeamish.
46
Do you think people have any idea what plastic is doing to us?
47
The majority, I would say, wouldn't.
48
In stark contrast to my home, it's almost impossible to find anyone using plastic in the Lucas household.
49
And that's not surprising, given that both Michaela
50
and Andrew Lucas are scientists on a crusade to prove that plastic is a silent,
51
toxic threat loitering in our everyday lives.
52
What haunts you about plastic?
53
If these plastic particles are getting into our body, they're staying there.
54
We're becoming a garbage patch.
55
I think we are the garbage patch already, but we just don't know the size of the garbage patch yet.
56
By garbage patch, they're talking about two evils evils,
57
microplastics, tiny, almost invisible shards that break off plastic products and get into our food,
58
drink and the air we breathe.
59
And then there are the toxic chemicals that leak out of them.
60
The ones we know the most about are called phthalates and bisphenols, commonly referred to as BPA.
61
And this is where the science gets really scary.
62
How many plastic chemicals are there?
63
Well, in a study that looked at the various chemicals added, they found up to 16 ,000 different chemicals.
64
that have been added to plastics.
65
And where do all these chemicals come from?
66
So since the 1950s, there's been an explosion in the ability to synthesise all sorts of different types of chemicals.
67
Because they're associated with a very big industry, they just get introduced and used without any testing.
68
And we're really the guinea pigs for the exposure of thousands of new chemicals.
69
How long have you been concerned about plastic?
70
I've been concerned about plastic for about five years now.
71
What do we do about this thing that we are constantly exposed to, that we know has got concerning evidence around emerging health problems and yet...
72
Like Michaela and Andrew Lucas,
73
GP Dr Kate Wiley fears the unknown consequences of plastics on both the planet and her patients.
74
We've got plastic in our brains.
75
We've got plastic in our reproductive organs.
76
There's plastic in human placentas.
77
What Kate thinks about plastic is alarming, but she's the first to admit that her fears are not definitive.
78
There needs to be much more scientific proof, which she says is still decades away.
79
What do we know that these particles are doing to us?
80
Well, this is a problem we don't really know yet.
81
So as a GP, you know, I can't say that, you know, X plastic product causes Y disease,
82
but the emerging evidence is around things like increasing our risks of heart attack and stroke.
83
We've got emerging data about plastics being associated with dementia, which is a very concerning thing.
84
As I really want to caveat, you know, this stuff is not a done deal.
85
We don't really have all the information we need, but the emerging data is enough that we should We should show caution about it.
86
Five months ago, Professor Michaela and Dr Andrew Lucas released their own data about the dangers of plastics, which stunned the world.
87
For their study, instead of adding plastics to a control group, they removed the threat to see what would happen.
88
We said, OK, what about if we drop exposure to these chemicals? can we drop
89
that and will it have a health benefit?
90
So we immediately shifted from what Hamid does to how do we treat it.
91
At the start of the experiment, the Lucases analysed urine samples of more than 200 people,
92
finding at least six toxic chemicals in each participant.
93
They were then made to live for seven days with minimal exposure to plastics.
94
from their toothpaste to their underwear, herbs and spices, even cooking utensils.
95
Plastic was taboo during the study.
96
We asked people, they were still living in their house, they were still going to work,
97
but we gave them food that had never touched plastic or had a low plastic exposure during processing and packaging.
98
The results were astounding.
99
In just that one week, the level of plastic chemicals found in each person reduced by up to 60%.
100
Were you shocked by the results?
101
I was very happy to see the results.
102
We were, you know, very surprised that we were able to reduce it in such a short period of time.
103
But it also gave us really hope that we can turn things around and in the long run, if you do that day -to -day,
104
will have a long -term health benefit.
105
Coming up, the dire warning.
106
Act now or risk a reproductive wipeout.
107
Now, if we get that wrong, it's the end of the human race, right?
108
There's nothing Cal Glansnig likes better than starting his day in the water.
109
Since he was a school kid, the now 26 -year -old has been campaigning to protect the ocean from plastic.
110
But now he's learning he also needs to protect himself.
111
With all the research that's come out, I've actually been learning more about what it's doing to our own bodies and our own health,
112
and that's absolutely petrified me because I don't think enough Australians know the truth of what plastic's doing to us.
113
Two years ago, Cal turned to local politics to champion his cause
114
and was elected to his local council in Sydney's Sutherland Shire.
115
He's also made a documentary.
116
using himself as a guinea pig to prove that humans are becoming more plastic.
117
For the first time, it made me think about the future in a different way.
118
Not just the planet's, but mine.
119
Tell me about that and why did you do that?
120
I wanted to do that because I'm someone who's cut so much plastic out of my life, as much as, you know, you sort of can.
121
Like, I don't drink out of plastic water bottles and switch out plastic topping balls, like all these different things.
122
So I thought, alright, I'll get tested and I'll see, OK, this is in me, it's probably in all my friends, all my family, all my community, probably most Australians.
123
Even though Cal has been trying to live plastic -free for years,
124
the samples he sent to the US for testing showed his body was saturated with toxic chemicals,
125
84 % higher than the average American. Were you shocked?
126
I was really shocked.
127
I remember when my mum heard the results as well, Like, she burst into tears.
128
Like, she felt extremely guilty for not just me, but my younger brother as well.
129
Like, we used to have, you know, lunch in plastic...
130
You know, put plastic in the microwave, put plastic in the dishwasher.
131
Like, for so many years, like, Mum and my dad just had no clue of what this was doing.
132
For Cal, the news gets worse.
133
The toxic chemicals found in his system were phthalates, which researchers suspect are contributing to a global fertility crisis.
134
It's a daunting prospect for a young man considering his own future.
135
I mean, the fact that phthalates are in me, which is, like, a chemical that's linked to fertility, is, like, yeah, you know, when I want to start to have a family,
136
like, to know that that could be a risk and an issue is, like, pretty scary.
137
In America, Julie and Eric Isaac know exactly what that uncertainty feels like.
138
They spent five years trying to have a baby.
139
I remember that feeling of, like, OK, I give up.
140
Like, there's nothing I can do.
141
It's never gonna happen.
142
We had no explanation or reason as to why it was happening.
143
People weren't really giving us good reasons.
144
Eric was eventually diagnosed with a low sperm count, but when he and Julie had all but given up the idea of becoming parents,
145
a moment of serendipity.
146
Researchers approached the couple to explore something they'd never contemplated.
147
Was the plastic hidden in their everyday lives, sabotaging their dream of starting a family?
148
So, after everything you had been through for five years,
149
When somebody suggested to you that plastic could be the cause of your infertility, did you believe it?
150
Oh, no, I did not believe it at all.
151
No, zero.
152
We thought, like, oh, this isn't...
153
Like, there's no way this study's real.
154
Like, what is this, you know?
155
And I guess until you have eyes to see the plastics around you
156
and really you have some sort of trigger to tell you, like, this might not be good for your health.
157
It's just an everyday part of life.
158
I genuinely didn't think much about it.
159
Desperate for a child, Eric and Julie signed up to a radical three -month human experiment,
160
which was then turned into the Netflix documentary The Plastic Detox.
161
Alongside five other infertile couples, they removed as much plastic as they could from their lives.
162
What happened to your sperm count?
163
So, after cutting out plastics and reducing my exposure to phthalates and BPAs as much as possible.
164
My sperm count went from 7 million to 77 million in 90 days.
165
It's also the quality went up.
166
The quality wasn't bad to begin with, but it improved towards the end.
167
And you put that down purely to eliminating plastic?
168
Yeah, I don't see what else it could have been.
169
We changed nothing else about our life, but it's not the plastic pieces in your balls
170
or in your testicles that I think you should be worried about it's these chemicals
171
that are basically invisible it's like most people don't don't know about it
172
one year later voila julie
173
and eric were pregnant with little rowan whether it was a stroke of luck
174
or their plastic intervention scientists still can't be certain
175
but these parents weren't the only winners five of the six couples who took part in the experiment now have babies
176
we still go oh is that is
177
that our baby we still can't believe it we still ask each other we'll look at each other
178
and be like do we actually have a son like is
179
this a dream do you want to pinch me like are we so it's the it's the absolute best
180
If you ask Professor Sarah Dunlop, those results are no coincidence.
181
The head scientist of plastics
182
and human health at Western Australia's Mindaroo Foundation says the changes in fertility trends around the world are a significant worry.
183
We know if you look at sperm counts in men, in humans, they're declining.
184
They've dropped by about 50 % over the last few decades and are predicted to go on declining.
185
Now, if we get that wrong, it's the end of the human race, right?
186
And her frightening warnings don't end there.
187
For couples who do get pregnant, Professor Dunlop says microplastics and toxic chemicals are now even being found in foetuses.
188
They're getting into unborn babies.
189
Our babies are born pre -polluted.
190
We're exposed without our consent.
191
It's one giant, uncontrolled experiment on our health, thanks to industrial chemicals.
192
That's what outrages me.
193
Some of these scientists argue that because you can't see that full picture at the moment, that it's causing unnecessary alarm.
194
Again and again, every time we look, we find harm.
195
We feel we find statistical links that are consistent.
196
So that in itself is giving us a big, big warning bell.
197
The more I hear, the more worried I am about what's going to be found
198
on the Petri dishes used to collect the tiny particles of plastic I'm unknowingly exposing my own young family to.
199
After the break, the results are in and they don't go down well.
200
So am I putting my kids in danger?
201
That's the, you know, the million -dollar question, isn't it?
202
Give you a bottle.
203
Yeah.
204
Busy mum, Kirsty Sweeney, has made more than a few bottles in her time.
205
You never know, dear, how much I love you.
206
Little Maisie is baby number three.
207
Maisie just has to fit in, doesn't she?
208
She does have to fit in.
209
Third child, you just slot right into the family.
210
Like many parents who want only the best for their children, Kirsty feeds Maisie her milk in a BPA -free bottle,
211
meaning the toxic bisphenol chemical in the plastic has been removed.
212
What do you know about BPA?
213
I guess it's on a lot of packaging.
214
You hear about it, you know, in articles.
215
You know that you should be looking for things without BPA.
216
Do you know anything about what it does to you?
217
I know a little bit.
218
So I know that, you know, if you're having microplastics and things like BPA can act like hormones in your body.
219
Which is true.
220
It's scary.
221
For years, Australians have believed there was such a thing as safe plastic, especially when buying products for our little ones.
222
Professor Michaela and Dr Andrew Lucas have been looking closely at what's actually in BPA -free plastics,
223
and they're sorry to say we're not being told the whole truth.
224
The way that these bottles are made requires a chemical like BPA,
225
and in this case it's a related chemical called BPS, to actually construct and produce that product.
226
And unfortunately, they're similar enough to have similar bad properties.
227
They've shown the same sort of results for this substitute chemical.
228
So, unfortunately, we are not any safer.
229
So, BPA -free is a con?
230
BPA -free is accurate, but it is a con.
231
It's Not News Kirstie was happy to hear.
232
She thought she was making a safer choice for her children.
233
I think it's misleading.
234
I think it's, you know, convincing you that you're buying a product that is safe for your baby and your child.
235
But if we don't know about any of the other chemicals and the plastics, then we assume, you know, it's good for us.
236
Do you think the people making the BPA -free products know that they're harmful?
237
I would say that the people
238
that are putting the formulations together understand that the BPS is very similar in its properties to the BPA.
239
So why would they do it?
240
Because it works and because it's not regulated against.
241
So because they're not breaking any rules by doing it?
242
That's correct.
243
We rely on companies and the regulations to basically tell us what's good and what's not good.
244
And if we don't get that information clearly, then how are we supposed to make good choices?
245
My days of buying BPA -free bottles and dummies are well behind me.
246
But I'm concerned there are other harmful plastics around my home.
247
After leaving Petri dishes scattered throughout my house for three weeks,
248
ecotoxicologist Dr Scott Wilson is about to deliver results I'm not sure I want to hear.
249
Is it bad news?
250
Hold your horses.
251
Hold your horses.
252
It turns out the Clancy home has higher levels of plastic than the average Australian household.
253
But it's not where I expect it.
254
Interestingly, we're finding the bedroom comes up as the highest fibre count.
255
Where my darling little eight -year -old sleeps.
256
That's correct.
257
So, we're finding more than double what you've got in the kitchen or the bathroom and,
258
let's say, four times as much as the living room.
259
Where could that plastic be coming from?
260
It could be a toy, it could be a carpet, it could be a clothing, it could be just everyday containers.
261
So, am I putting my kids in danger?
262
That's the million -dollar question, isn't it?
263
So, I got the results...
264
Given my husband, Luke, has been worried about plastic for some time, I knew I was in for a difficult conversation.
265
Because I don't feel comfortable with what they told me today.
266
I kind of had expectations that we would get results that you weren't expecting, but are they bad or...?
267
So we're slightly above the average Australian household when it comes to plastics.
268
Above the average?
269
Above, yeah.
270
But that shocked me.
271
That shocks me.
272
What really got me was 44 % of what they found in this house was in Amelia's room.
273
Wow, that does shock me a lot.
274
If there's even a tenuous link, if it's a possibility, wouldn't you want to remove it from the kids' bedrooms?
275
I would.
276
Knowing that my eight -year -old daughter's bedroom has high levels of plastic fibres in it that she's breathing in is alarming.
277
Dr Wilson says it's most likely because this room has carpet.
278
So what can we do to make our home safer?
279
We've started here in the kitchen by simply replacing things like plastic chopping boards and cooking utensils with these wooden ones.
280
These small easy steps researchers are adamant will go a long way to shield us from the potential dangers of plastic.
281
There's everywhere you look there's plastic and the problem with
282
that is that you know we keep making more
283
but we're not dealing with it what are we where does
284
it go GP dr. Kate Wiley says the days of simply accepting plastic as a convenient
285
and cheap option need to be reconsidered whose job is it
286
to get control of this situation the industry themselves you know
287
they have a responsibility to protect the community from the harm of their product, and then always it comes back to government to make regulations that support community health.
288
Dr Wiley says the government is not doing its job
289
and needs to do more to not only protect the environment from plastic, but people too.
290
We live in this crazy time in human history where we have all these threats that are facing us, that we can name them.
291
It's right in front of us.
292
It's as plain as the nose on our face, and yet we just fob it off.
293
Environmental crusader Cal Glansnick agrees.
294
He's made it his mission to shout from every rooftop what he believes is the simple truth, that plastic is not fantastic.
295
We say, I've got to recycle more, I've got to cut my own plastic, but it shouldn't be on us.
296
Like, we live busy lives, we've got other things to worry about.
297
Like, this is a political responsibility because it is a health crisis.
298
We're not trying to get ourselves to Mars.
299
Like, we're just trying to stop plastic ending up in our ocean, in our animals and in our bodies.
300
Have you asked the government why they haven't acted?
301
What they've said is that they're not hearing from enough Australians.
302
Like, that is the answer from, yeah, the Environment Minister's mouth.
303
What did you say back?
304
Watch this face.
305
The Federal Health Minister's office told us the problem of plastics wasn't their concern and referred us to the Environment Minister, who was unavailable for an interview.
306
On this week's podcast, Extra Minutes, Dimity Clancy speaks with Carl Glansnig about ways to free ourselves from plastic.
307
What can the everyday Aussie do?
308
I think plastic water bottles is such an easy one.
309
Australians spend about $560 million on plastic water bottles every single year.

¿Qué es la Técnica de Shadowing?
Shadowing es una técnica de aprendizaje de idiomas respaldada por la ciencia, desarrollada originalmente para la formación de intérpretes profesionales y popularizada por el políglota Dr. Alexander Arguelles. El método es simple pero poderoso: escuchas audio en inglés nativo y lo repites en voz alta de inmediato, como una sombra que sigue al hablante con solo 1-2 segundos de retraso. A diferencia de la escucha pasiva o los ejercicios de gramática, el shadowing obliga a tu cerebro y músculos de la boca a procesar y reproducir simultáneamente patrones de habla reales. Las investigaciones muestran que mejora significativamente la precisión de la pronunciación, la entonación, el ritmo, el habla conectada, la comprensión auditiva y la fluidez al hablar, convirtiéndola en una de las metodologías más efectivas para la preparación del IELTS Speaking y la comunicación en inglés en el mundo real.
