1
Nearly everything we eat and drink is wrapped in plastic.
2
In fact, global plastic production more than doubled between 2000 and 2022.
3
And now we're realizing it's showing up in our bodies too.
4
One recent study showed the level of microplastics in the frontal
5
cortex of our brains increased by about 50% between 2016 and 2024.
6
You cannot take the current exposure levels to plastic
7
and say let's double them in the human race and just see what happens.
8
I mean, that's just idiotic.
9
The problem is that plastic never fully decomposes.
10
It just breaks down into smaller and smaller pieces.
11
When it becomes smaller than five millimeters, that's about the width of a pencil eraser.
12
It's called a microplastic.
13
But then a subset called nanoplastics can get much, much smaller.
14
So small that they can't even be seen with the human eye.
15
There has been increasing chronic disease.
16
We know that some of that is from many of these chemicals that are used in plastics.
17
Plastic is in some ways an amazing material.
18
It has this amazing breadth of uses that makes it a very valuable material.
19
It also happens to be very inexpensive.
20
It's cheap to make.
21
And it has long been inexpensive, but it's become even cheaper to make more recently.
22
And when you combine inexpensive with very useful, you're going to have a lot of demand for this product.
23
Plastic production is a big industry, $880 billion in fact.
24
And as big oil faces weakened demand for gasoline, it's increasingly turned to plastic.
25
Aside from the already massive plastic waste problem that the world is facing, it's now in our bodies.
26
And with more research emerging that shows its harm on our health, why is plastic production increasing?
27
And who's reaping the benefits from it?
28
In that study about plastic in our brains, researchers at the University of New Mexico studied samples from cadavers.
29
Based on those samples, they calculated
30
that the total mass of plastic from the 2024 brains they evaluated would equate to about 7 grams, about the size of a plastic spoon.
31
Tracy Woodruff wasn't involved in the brain study, but is a microplastics researcher.
32
She's evaluated thousands of studies on this topic.
33
We're able to conclude based on those studies that microplastics are suspected to adversely impact reproductive health,
34
respiratory health, and effects on the digestive system.
35
And that the links to these mechanisms that we saw could also could increase the risk of colon cancer and lung cancer.
36
Almost every single thing we buy from the grocery store comes wrapped in plastic, which sheds microscopic particles onto our food.
37
It's also contaminated our food chains.
38
Researchers found
39
that 99% of the fish they studied off the coast of Oregon were found to contain microplastics in their muscle tissue.
40
It's been found to be released in our mouths from simply chewing a piece of gum.
41
Researchers have even found them in fruits and vegetables.
42
As humans we are becoming part plastic.
43
That is the reality, right?
44
And plastic has over 16,000 chemicals.
45
We have only, you know, had studies and research that has about a quarter of them documented as harmful,
46
but we just haven't had the time and resources to explore how these other chemicals may be impacting us.
47
While there is definitive research to prove microplastics are inside of us, the exact effects on our bodies is difficult to pinpoint.
48
Many studies have found a correlation between microplastics and chronic disease, but cannot establish a causation.
49
For example, the study on our brains analyzed samples of people with dementia
50
and found much higher levels of microplastic in them compared to the brains without the disease.
51
There are of course many other lifestyle or genetic factors that could have caused dementia.
52
On its website, the FDA reiterates the lack of causality by saying, Current scientific evidence does not demonstrate that the level of microplastics
53
or nanoplastics detected in our foods pose a risk to human health.
54
Consider microplastics to be sort of a toxic delivery mechanism.
55
All the chemicals that are attached to the plastic that make up the plastic, that soften the plastic or that block UV light
56
or do all the things that give it its characteristics that make it so versatile, a lot of those are pretty toxic substances.
57
Petrochemicals, the building blocks of plastic, are produced from oil and gas.
58
It's a small but profitable area of the fossil fuel industry.
59
In the US, only about 1.5% of natural gas is converted into chemicals
60
that are used to make plastic and other consumer products.
61
But as oil demand declines from EV adoption, US tariffs, and a slowing of economic growth in India and China, industry giants are investing heavily into chemical production.
62
Renewables are coming in very inexpensively, and so renewables are actually on the margin in cutting
63
or reducing the amount of additional natural gas that would have been built otherwise.
64
Plastic production is projected to grow more than 40% between 2025 and 2040.
65
In its 2024 outlook, British Petroleum, or BP, said, materials.
66
Exxon Mobil and Shell made over $110 billion in combined revenue from their chemical businesses in 2024.
67
Plastics is the growth area.
68
They know how to do it.
69
They already have access to the gas that you need to make plastics.
70
They're not constrained at all by what happens to people.
71
They don't care about that.
72
They just see this as, OK, what do my shareholders need?
73
How am I going to make a ton of money?
74
We have recycled 80 million pounds of plastic that otherwise would have gone to landfills.
75
And we have plans to ramp that recycling up to a billion pounds by 2027.
76
In 2020, Saudi Aramco, the biggest oil company in the world, bought a 70% stake in petrochemical company, Sabic.
77
While fourth quarter 2024 results were lower than expected, Sabic made nearly $35 billion from petrochemicals last year.
78
Sabic and Exxon are two of the largest players in the polyethylene plastics industry.
79
I think that the oil and gas majors all see a major opportunity.
80
They've been investing very heavily, billions of dollars, into building plastic producing facilities.
81
So when they're losing some of their profit center or expect to be losing some of their core profit centers, this is a place where they might be able to make up some of that lost profit.
82
Fracking has made the U.S into the world's biggest oil producer pumping out nearly 13.5 million barrels per day.
83
And a global surplus of oil, and particularly natural gas, means more plastic production.
84
The bottom line is that it's really coming from the fact that we have so much natural gas and plenty of ethane, and it's pretty easy to get that ethane,
85
so that the actual feedstock, if you will, so that what's used to create plastics is really cheap in the United States.
86
With widespread investments in plastics growth, the market is becoming highly oversaturated.
87
The margins on chemicals are compressing and plastic supply is projected to increasingly outpace demand.
88
Shell, for example, felt that firsthand in its most recent quarter.
89
This isn't about we need more plastic.
90
This is about them pushing more plastic on us because they're looking for new markets for their products.
91
And I think one of the concerns that people have is that once they put in all this infrastructure, because it's expensive, right?
92
You have to build a facility and all the mechanisms for transporting it from the ground to the product.
93
It's gonna be really hard to roll that back.
94
Plastic was first created in the early 1900s.
95
As well as the development of new man-made plastics and fabrics.
96
But wide-scale production didn't ramp up until the 50s.
97
The public was sold on the notion of disposability, but over the following decades, began waking up to the pollution crisis it was creating.
98
There were all sorts of efforts in the 1970s and 80s
99
and even in the 90s to ban plastic bags or to ban plastics in general.
100
And that is really what was at the root of the industry's pivot to recycling.
101
Because they saw recycling as a way to deflect and defend against those efforts to ban their products.
102
A report by the Center for Climate Integrity alleges that the plastics industry spent years making quote,
103
performative investments and would roll back research initiatives or quietly shut down facilities when regulatory threats simmered.
104
Just last year, the Attorney General of California sued ExxonMobil over a decades-long campaign of recycling deception.
105
If the public was convinced that their single-use throwaway consumer lifestyle was supported by recycling and that it was environmentally friendly,
106
they would buy more and more and it would drive the profits of ExxonMobil up and up.
107
And so that's the idea, but it's based on a lie.
108
It's illegal.
109
We've sued them in court and we're here to hold them accountable.
110
Within two months of the lawsuit, Exxon announced a commitment to invest $200 million in boosting recycling capacity in its Texas plant.
111
In January 2025, ExxonMobil countersued the California AG and other environmental groups for defaming and disparaging the company's recycling initiatives.
112
We've seen this growing trend where activists and ideologues, particularly in the climate space, and then some politicians, particularly state attorney generals,
113
are hijacking and abusing legitimate processes to advance their own selfish agendas.
114
I think that was certainly true with the state attorney general, Rob Bonta.
115
He was lying, lying about our company, lying about our technology, impugning the character of our people,
116
interfering with our business, and probably most importantly, getting in the way of improving the environment.
117
I don't think anybody really was quite aware of the depth of the fraud that the industry was perpetrating on the public.
118
I mean, they knew from the beginning that the economics of plastic recycling would never work.
119
Only about 9% of plastic waste worldwide was recycled in 2019.
120
In the U.S., that number is even lower at 5%.
121
So, why aren't more plastics being recycled?
122
It's a complicated chain.
123
There is a problem with collecting and sorting and processing the plastics.
124
There is a, the current recycling technology has its limits.
125
The plastic today is not a simple single element of plastic.
126
They are very complicated structures to achieve the properties that we're looking for in the use of plastic.
127
And so, many of those properties make them inconsistent for mechanical recycling.
128
It is simply cheaper to make new plastic than to recycle, especially considering the abundance of gas and oil.
129
There are no incentives for a company to switch out of plastics.
130
There are no incentives for a company to use recycled plastics.
131
It's more expensive.
132
The only incentive they have is that many companies want to be socially responsible.
133
Political backing has also been instrumental in making all of this possible. While U.S.
134
Secretary of Health and Human Services, RFK Jr., has said reassessing the levels of chemicals and plastic in our food is a priority,
135
the Trump administration as a whole has taken a pro-plastic stance by aggressively deregulating the energy industry.
136
It's cutting incentives for renewables and opening federal lands for more oil and gas drilling.
137
This push for more drilling comes despite the fact that the U.S is already producing a surplus.
138
Current deregulatory efforts by the current federal government in the United
139
States giving less to worry about for the business executives in the oil and gas industry relating to plastics.
140
And so I don't anticipate there's going to be any regulation on plastics in the next few years.
141
Between 2014 and 2024, the oil and gas industry spent over $1.4 billion on federal lobbying.
142
Having worked in the government, there are stakeholders, and those are really fossil fuel
143
and the chemical producing companies
144
that have a financial stake in what the government says about whatever these topics are related to these toxic chemicals.
145
CNBC reached out to Shell, Exxon and SABIC.
146
However, none of them agreed to an interview.
147
Exxon referred us to a previous interview with CNBC.
148
Shell told us
149
that it believes the global plastic treaty provides a unique opportunity
150
to mobilize global action to tackle plastic pollution by creating an effective
151
and sustainable plastic circular economy while supporting an inclusive of transition for all stakeholders.
152
While it is impossible to avoid entirely, the good news is there are a few realistic ways to reduce your exposure to microplastics.
153
Cutting out plastic water bottles is one major step everyone can take.
154
There are hundreds of thousands of microplastics floating around in every liter of bottled water.
155
We know that from empirically based studies
156
that you can reduce your exposures to these chemicals that are found in plastic that we know are toxic.
157
So by extrapolation, you can also reduce your exposures to microplastics.
158
And so some of them are and some of them are really super easy, like don't microwave plastic.
159
That's a really easy one.
160
A 2023 study found
161
that microwaving plastic caused the highest release of microplastics into food
162
compared to other usages like storing it in the refrigerator or at room temperature.
163
No one's talking about getting rid of heart valves or, you know, no one's talking about getting rid of essential uses of plastic plastic like plastics in your car dashboard
164
or whatever it is.
165
What we're talking about is plastics that are single use, plastics that are completely unnecessary,
166
plastics where, you know, you don't have to individually wrap like every leaf of lettuce, which it seems to be where we're headed with this stuff.
167
We're unquestionably as a society better off having plastics than no plastics, but we're facing the consequences of having those plastics.
168
And what can we do to try to mitigate those consequences?
169
The American Chemistry Council, a major trade association for plastics, says that plastic packaging can make food last longer.
170
There is also evidence that the carbon emissions saved from reducing food waste outweighs the emissions from producing the plastic packaging.
171
But none of this accounts for the impact on human health.
172
The ACC's VP of Regulatory and Scientific Affairs shared the following comment with CNBC.
173
We can now detect incredibly tiny amounts of substances like microplastics, but finding something at extremely low levels does not mean it's harmful.
174
The science on microplastics is evolving.
175
ACC and our global counterparts are funding research to advance the science so that decisions are guided by sound,
176
data-driven evidence that weighs any potential risks against the essential role plastics play in our daily lives.
177
These types of synthetic plastic and the plastic
178
that we are talking about really has only been readily used in society for the past 70 years.
179
So it's the amount of evidence and understanding of how plastic accumulates within our bodies over time is really in its infancy.
180
This chart shows the level of published research surrounding microplastics in the National Library of Medicine over the past decade.
181
Both scientists and the general public are just beginning to understand the implications of microplastics, given that most of the studies on them have recently emerged.
182
We're just doing some studies now looking at exposures to
183
pregnant women who were previously pregnant and they're still exposed to DDT like that was banned in 1970.
184
And that's because once we pollute the environment, it just hangs around and we are just continuously exposed.
185
One of the things that is really lacking in terms of government policy
186
and regulation is dealing with these pollutants that are persistent and bioaccumulative because if make a mistake with them, your mistake is forever.
187
You know, one of the most important things you can do is vote
188
and show up to local community events and really advocating, you know, for stronger laws and regulations on plastic.
