Climate change is a pollution problem, and countries know how to deal with pollution threats – think DDT and acid rain

Published

Climate change could seem insurmountable. But if you happen to take a closer have a look at its causes, you realize that history is stuffed with similar health and environmental threats that humanity has overcome.

The predominant explanation for climate change is carbon dioxide produced by burning fossil fuels – is just one other pollutant. And countries know how to reduce harmful pollutants. They did so with the pesticide DDT, lead paint, and power plant emissions that caused acid rain, amongst many others.

In each case, growing public outcry eventually led to policy changes, despite industry resistance. Under pressure from laws and regulations, industry ramped up production of safer alternatives.

I’m earth and environmental scientistand my latest book “Reclaiming our planet,” explores the teachings of history in overcoming seemingly insurmountable threats. Here are some examples:

DDT ban despite industry opposition

DDT was the primary truly effective pesticide and considered miraculous. Killing mosquitoes and lice, eliminated malaria and other diseases in lots of countries, and in agriculture it saved tons of crops.

After World War II, DDT was utilized in farms, buildings and gardens throughout the United States. However, it also had its drawbacks. accumulated in mother’s milk to levels that would deliver a toxic dose to infants. Women were It was discouraged breastfed their children within the Sixties due to the risks.

In addition, DDT bioaccumulated within the food chain to toxic levels in peak species reminiscent of raptors. This weakened eggshells to the purpose that brood moms crushed their eggs. White-tailed eagles were reduced to 417 breeding pairs throughout North America by 1967 and were placed on the endangered species list.

Biologist Rachel Carson documented the damage DDT caused to her body 1962 book “Silent Spring”“and thus launched the general public environmental movement. Despite disinformation campaigns and attacks from the chemical industry, enormous social pressure on politicians led to congressional hearings, state and federal restrictions and finally the USA ban on the overall use of DDT in 1972.

White-tailed Eagles recovered up to 320,000 within the United States by 2017, in regards to the same because the population before European settlement. The chemical industry, faced with the ban on DDT, quickly developed much safer pesticides.

Gathering evidence on the risks of lead

Application of lead increased dramatically within the twentieth centuryespecially in paints, plumbing and gasoline. It was so common that nearly everyone was exposed to metal that, according to research, could also be harmful the kid’s kidneys, liver, cardiovascular system and brain development.

Clair “Pat” Patterson, a geochemist on the California Institute of Technology, has shown that Americans were continually exposed to lead at near toxic levels. Human skeletons from the Sixties were found to have up to 1200 times lead of ancient skeletons. Today health standards say that it is no protected level of lead within the blood.

Despite threats each personal and skilled, and an industry disinformation campaign, Patterson and his supporters evidence has been collected from years warn the general public and ultimately pressure politicians to ban the usage of lead in lots of applications, including petrol AND residential paints.

After the regulations were introduced, the industry accelerated production of substitutesAs a result, the extent of lead within the blood of kids reduced by 97% over the following few a long time. Although lead exposure is now less common, some persons are still exposed to dangerous levels present in homes, pipes and soil, often in low-income neighborhoods.

Stopping Acid Rain: An International Concern

Acid rain is primarily brought on by the discharge of sulfur dioxide into the air in the course of the burning of coal, high-sulfur oil, and the smelting and refining of metals. interacts with rain or fogThe acid rain that falls can destroy forests, kill lake ecosystems, dissolve monuments and corrode infrastructure.

The damage brought on by acid rain in Europe and North America within the twentieth century showed the world that air pollution, which is not limited to national borders, can grow to be a world crisis requiring international solutions.

The problem of acid rain began greater than a hundred years ago, but sulfur dioxide levels grew rapidly after World War IIIn 1952, a thermal inversion occurred in London, which resulted within the concentration of sulfur dioxide and other air pollutants being so high that killed 1000’s of individualsAs damage to forests and lakes worsened across Europe, countries signed international agreements In the Eighties, actions were taken to reduce sulfur dioxide emissions.

In the US, emissions from Midwestern power plants killed fish and trees within the pristine Adirondacks. The destruction, health problems and quite a few disasters outraged public opinion, to which politicians responded.

Sulfur dioxide listed as certainly one of six criteria for air pollution in groundbreaking study U.S. Clean Air Act of 1970which required the federal government to set limits on its release. Power plants scrubbers installed to capture pollution and over the following 40 years, the concentration of sulfur dioxide within the U.S. reduced by about 95%.

Parallels with climate change

There are many similarities between these examples and climate change today.

Mountains scientific evidence show how carbon dioxide emissions are created by burning fossil fuels in vehicles, factories and power plants They are warming the planetThe fossil fuel industry has begun to exploit its political power AND disinformation campaigns a long time ago to block regulations the aim of which was to decelerate climate change.

People all around the world are struggling with increasing heat and weather disasters brought on by global warming. calling for motion to stop climate change and spend money on cleaner energy.

First Earth Dayin 1970, it attracted 20 million people. Recent years have seen a change in attitudes towards climate change and attracted hundreds of thousands people all around the world.

The challenge was to get politicians to act, but that is is slowly changing in lots of countries.

The United States has begun investing in scaling up several tools to mitigate climate changeincluding electric vehicles, wind turbines and solar panels. Federal and state policies reminiscent of requirements for renewable energy production and reducing greenhouse gas emissions are also key to pushing industries to switch to less harmful alternatives.

Climate change is a global problem that may require worldwide motion. International agreements are also helping more countries take steps forward. One change that countries have been discussing for years could help bolster those efforts: ending billions of dollars in taxpayer-funded fossil fuel subsidies and allocating these funds to healthier solutions could help decelerate climate change.

The family of Tire Sampson, the 14-yr-old who tragically died on an amusement park ride in Orlando, Florida, in 2022, has been awarded $310 million in a civil lawsuit.

Tire, who was visiting ICON Park along with his family on March 24, 2022, fell from the FreeFall drop tower. Although he was taken to a nearby hospital, he didn’t survive his injuries.

Now, greater than two years later, a jury has held the vehicle manufacturer, Austria-based Funtime Handels, responsible for the accident and awarded the Tire family $310 million. According to reports from local news stations WFTV AND KSDKthe jury reached its verdict after about an hour of deliberation.

Tyre’s parents will each receive $155 million, according to attorney spokesman Michael Haggard.

Attorneys Ben Crump and Natalie Jackson, who represented Tyre’s family, shared their thoughts on this landmark decision via X (formerly Twitter). “This ruling is a step forward in holding corporations accountable for the safety of their products,” they said in a statement.

Lawyers stressed that Tyre’s death was attributable to “gross negligence and a failure to put safety before profits.” They added that the ride’s manufacturer had “neglected its duty to protect passengers” and that the substantial award ensured it could “face the consequences of its decisions.”

Crump and Jackson said they hope the result will encourage change throughout the theme park industry. “We hope this will spur the entire industry to enforce more stringent safety measures,” they said. “Tire heritage will provide a safer future for drivers around the world.”

An investigation previously found that Tyre’s harness was locked through the descent, but he dislodged from his seat through the 430-foot fall when the magnets engaged. Tire’s death was ruled the result of “multiple injuries and trauma.”

ICON Park said at the time that it could “fully cooperate” with the authorities.

HIV/AIDS Advocate, A. Cornelius Baker


A. Cornelius Baker, a tireless advocate of HIV and AIDS testing, research and vaccination, died Nov. 8 at his home in Washington, D.C., of hypertensive, atherosclerotic heart problems, in response to his partner, Gregory Nevins.

As previously reported, Baker was an early supporter for people living with HIV and AIDS within the Nineteen Eighties, when misinformation and fear-mongering in regards to the disease were rampant.

According to Douglas M. Brooks, director of the Office of National AIDS Policy under President Obama, it was Baker’s Christian faith that guided him toward compassion for others.

“He was very kind, very warm and inclusive – his circles, both professional and personal, were the most diverse I have ever seen, and he was guided by his Christian values,” Brooks told the outlet. “His ferocity was on display when people were marginalized, rejected or forgotten.”

In 1995, when he was executive director of the National AIDS Association, Baker pushed for June 27 to be designated National HIV Testing Day.

In 2012, he later wrote on the web site of the Global Health Advisor for which he was a technical advisor that: “These efforts were intended to help reduce the stigma associated with HIV testing and normalize it as part of regular screening.”

Baker also feared that men like himself, black gay men, and other men from marginalized communities were disproportionately affected by HIV and AIDS.

Baker pressured the Clinton administration to incorporate black and Latino people in clinical drug trials, and in 1994 he pointedly told the Clinton administration that he was bored with hearing guarantees but seeing no motion.

According to Lambda Legal CEO Kevin Jennings, yes that daring attitude that defines Baker’s legacy in the world of ​​HIV/AIDS promotion.

“Cornelius was a legendary leader in the fight for equality for LGBTQ+ people and all people living with HIV,” Jennings said in a press release. “In the more than twenty years that I knew him, I was continually impressed not only by how effective he was as a leader, but also by how he managed to strike the balance between being fierce and kind at the same time. His loss is devastating.”

Jennings continued: “Cornelius’ leadership can’t be overstated. For many years, he was one in all the nation’s leading HIV/AIDS warriors, working locally, nationally and internationally. No matter where he went, he proudly supported the HIV/AIDS community from the Nineteen Eighties until his death, serving in various positions including the Department of Health and Human Services, the National Association of Persons with Disabilities AIDS, and the Whitman-Walker Clinic . Jennings explained.

Jennings concluded: “His career also included several honors, including being the first recipient of the American Foundation for AIDS Research Foundation’s organization-building Courage Award. Our communities have lost a pillar in Cornelius, and as we mourn his death, we will be forever grateful for his decades of service to the community.”

Kaye Hayes, deputy assistant secretary for communicable diseases and director of the Office of Infectious Diseases and HIV/AIDS Policy, in her comment about his legacy, she called Baker “the North Star.”.

“It is difficult to overstate the impact his loss had on public health, the HIV/AIDS community or the place he held in my heart personally,” Hayes told Hiv.gov. “He was pushing us, charging us, pulling us, pushing us. With his unwavering commitment to the HIV movement, he represented the north star, constructing coalitions across sectors and dealing with leaders across the political spectrum to deal with health disparities and advocate for access to HIV treatment and look after all. He said, “The work isn’t done, the charge is still there, move on – you know what you have to do.” It’s in my ear and in my heart in the case of this job.

Hayes added: “His death is a significant loss to the public health community and to the many others who benefited from Cornelius’ vigilance. His legacy will continue to inspire and motivate us all.”

Baker is survived by his mother, Shirley Baker; his partner Nevins, who can be senior counsel at Lambda Legal; his sisters Chandrika Baker, Nadine Wallace and Yavodka Bishop; in addition to his two brothers, Kareem and Roosevelt Dowdell; along with the larger HIV/AIDS advocacy community.

Bovaer is added to cow feed to reduce methane emissions. Does it pass into milk and meat? And is it harmful to humans?

Published

on

By

There are growing concerns in regards to the use of feed supplements, Bowar 10to reduce methane production in cows.

Bovaer 10 consists of silicon dioxide (mainly sand), propylene glycol (food stabilizer approved by Food Safety Australia New Zealand) and lively substance 3-nitrooxypropanol (3-NOP).

There has been an enormous amount of misinformation in regards to the safety of 3-NOP, with some milk from herds fed this additive being labeled “Frankenmilk”. Others feared it could get to humans through beef.

The most significant thing is that 3-NOP is secure. Let’s clear up some major misconceptions.

Why do we want to limit methane production?

In our attempts to limit global warming, we’ve placed the best emphasis on CO₂ because the major man-made greenhouse gas. But methane is also a greenhouse gas, and although we produce less of it, it is: a much stronger greenhouse gas than CO₂.

Agriculture is the largest a man-made source of methane. As cattle herds expand to meet our growing demand for meat and milk, reducing methane production from cows is a vital way to reduce greenhouse gas emissions.

There are several ways to do that. Stopping bacteria within the stomachs of cows that produce methane one approach is to produce methane.

The methane produced by cows and sheep doesn’t come from the animals themselves, but from the microbes living of their digestive systems. 3-NO stop the enzymes that perform the last step of methane synthesis in these microorganisms.

3-NOP is not the one compound tested as a feed additive. Australian product based on seaweed, Rumin8for instance, it is also in development. Saponins, soap-like chemicals present in plants, and essential oils as well has been examined.

However, 3-NOP is currently one of the popular effective treatments.

But is not it poison?

There are concerns on social media that Bovaer is “poisoning our food.”

But, as we are saying in toxicology, it’s the dose that makes the poison. For example, arsenic is deadly 2–20 milligrams per kilogram of body weight.

In contrast, 3-NOP was not lethal on the doses utilized in safety studies, up to 600 mg 3-NOP per kg body weight. At a dose of 100 mg per kg body weight in rats, it didn’t cause any adversarial effects.

What about reproductive issues?

The effect of 3-NOP on the reproductive organs has generated numerous commentary.

Studies in rats and cows showed that doses of 300–500 mg per kg body weight caused: contraction of the ovaries and testicles.

In comparison, to achieve the identical exposure in humans, a 70 kg human would want to eat 21–35 grams (about 2 tablespoons) of pure 3-NOP every day for a lot of weeks to see this effect.

No human will likely be exposed to this amount because 3-NOP doesn’t pass into milk – is fully metabolized within the cow’s intestines.

No cow will likely be exposed to these levels either.

What about cancer?

3-NOP is not genotoxic or mutagenicwhich implies it cannot damage DNA. Thus, the results of 3-NOP are dose-limited, meaning that small doses will not be harmful, while very high doses are (unlike radiation where there is no secure dose).

Scientists found that at a dose of 300 mg per kilogram of body weight benign tumors of the small intestine of female ratsbut not male rats, after 2 years of every day consumption. At a dose of 100 mg 3-NOP per kg body weight, no tumors were observed.

Cows eat lower than 2 grams of Bovaer 10 per day (of which only 10% or 0.2 grams is 3-NOP). This is about 1,000 times lower than the appropriate every day intake 1 mg 3-NOP per kg body weight per day for a cow weighing 450 kg.

This level of consumption will likely be not the result in cancer or any of them other adversarial effects.

So how much are people exposed to?

Milk and meat consumers will likely be exposed to zero 3-NOP. 3-NOP doesn’t penetrate milk and meat: is completely metabolized within the cow’s intestines.

Farmers could also be exposed to small amounts of the feed additive, and industrial employees producing 3-NOP will potentially be exposed to larger amounts. Farmers and industrial employees already wear personal protective equipment to reduce exposure to other agricultural chemicals – and it is advisable to do that with Bovear 10 as well.

How widely has it been tested?

3-NOP has been in development for 15 years and has been subject to multiple reviews by European Food Safety Authority, UK Food Safety Authority AND others.

It has been extensively tested over months of exposure to cattle and has produced no unintended effects. Some studies actually say so improves the standard of milk and meat.

Bovaer was approved for use in dairy cattle by the European Union from 2022 and Japan in 2024. It is also utilized in many other countries, including: in beef products, amongst others Australia.

A really small amount of 3-NOP enters the environment (lower than 0.2% of the dose taken), no accumulates and is easily decomposed subsequently, it doesn’t pose a threat to the environment.

Since humans will not be exposed to 3-NOP through milk and meat, long-term exposure is not an issue.

What does Bill Gates have to do with this?

Bill Gates has invested in a distinct feed processing method for methane, Australian seaweed-based Rumin8. But he has nothing to do with Bovaer 10.

The Bill & Melinda Gates Foundation awarded research grants to the corporate producing 3-NOP for malaria control researchnot for 3-NOP.

The bottom line is that adding 3-NOP to animal feed doesn’t pose any risk to consumers, animals or the environment.
