My town became environmentally conscious and so did I
Growing up, I realized that children are a product of their environment, so let me tell you a little bit about mine: I grew up in Secaucus, N.J., a town called “the Jewel of the Meadowlands.” My suburban hometown exists within a large ecosystem of wetlands, the Meadowlands, through which the Hackensack River flows. But with post-agricultural pig farm effluent and debris from New York’s train station decay being dumped into the area, the Meadowlands became a jewel in need of polishing.
Secaucus is working to recover the natural marshes by designating them as protected so fewer apartment complexes can be built and begin to sink a few years down the road, which has happened in the past. The town became environmentally conscious, and existing within that environment, I did the same.
In high school, I worked with the Secaucus Environmental Department for over three years as part of the Next Generation Community Leaders, or NGCL, program created by the Lindsey Meyer Teen Institute. Little did I know just how much this experience would influence my life. Throughout that time, I learned about climate change, the planet’s environmental challenges, and the actions we need to take to reduce our footprint. I helped implement a plastic bag and Styrofoam ban, designed a food waste composting system at my high school and local gardens and created eco-friendly living PSAs. I canvassed to promote eco-friendly living and educated residents on how to compost at home.
I also certified local businesses as “green,” depending on whether they followed practices set by the Sustainable Jersey network. These practices included recycling, reducing food waste, not using Styrofoam, etc. My contributions to the environmental department helped Secaucus to earn recognition from Sustainable Jersey as a Silver Certified Community.
That experience showed me how local actions can create change. By educating residents in Secaucus, we altered their behaviors, if even slightly, to be more environmentally conscious. Residents began to grow produce in the community gardens, compost at home and reduce their plastic bag usage. I witnessed how humans responsible for harming the planet have the potential to make changes to fix it and make it better for future generations. From that day forward, I carried that responsibility with me.
I will be honest: I don’t know the current status of those projects I worked on in Secaucus. I hope that residents are still composting at home and that those businesses continue their green practices.
I began my journey into learning about sustainability at USC with a major in industrial and systems engineering and a minor in law and public policy. Although these are not fields directly tied to the climate ecosphere, my advocacy in Secaucus made me realize that a systematic mindset and policy knowledge would be strong tools with which I can effect change within both the government and private sector in advocating for larger-scale sustainability solutions. With the opportunities provided by USC, I knew I could get involved in environmentalism and sustainability without having to be an environmental science major.

If you asked freshman Alyssa what her ultimate career goal was, she would have said, “Facilitate systemic change within the bureaucracy through ecological and climate-preservation policies to make society more sustainably conscious.” I wrote this on an index card and kept it in my backpack throughout college to constantly remind me of the goal because being an environmentalist can be discouraging, given the current climate.
Since then, I think I would have made freshman Alyssa proud. I was accepted into the USC Student Sustainability Committee and became a mentor to new members. The SSC acts as a representative for the student body within the Presidential Working Group for Sustainability. We work on projects such as getting reusable takeout containers in dining halls, ensuring ongoing campus construction is adhering to green practices, and creating a central physical space where sustainability-minded students can gather.
As a member of the SSC, I ensured that sustainability would become a standard educational practice at USC and change student behaviors toward respecting their environment. I continued my education at USC by pursuing a master’s in sustainable engineering, and I have earned the distinction of a National Academy of Engineering Grand Challenges Scholar by focusing on sustainability.

My environmental pursuits have culminated in my becoming a Los Angeles County Youth Climate commissioner in the world’s first such organization. We have canvassed the youth in L.A. County and discovered that their top environmental priorities are cleaner air, green spaces and green buildings.
Now, as a member of the legislative committee, I track all federal and state measures that relate to these priorities and bring them to the attention of the county Board of Supervisors so that they can weigh in on whether the legislation should be amended, supported or rejected. We are working actively to support legislation currently going through the U.S. Senate that would call for establishing opportunities for youths to be involved in policy development so they can ensure a healthy environment for their future and those to come.
Since children are a product of their environment, we should help future generations have a good environment to live in. With the environment constantly changing due to global warming, future generations will have a chance only if we work to make the world sustainable starting today. Instead of forcing future generations to learn how to survive to fix the environmental mistakes we are making today, they should have the opportunity to live without the repercussions of the past.
I witnessed the negative effects of a mistreated environment in my hometown, and I want to make sure future generations aren’t suffering from the consequences of what we are doing. With a sustainability mindset, local changes can influence the politicians and create the systemic change needed to get the biggest offenders under control. One of the significant steps is behavioral changes, which can begin locally and be brought by people not even studying in the environmental field, just like me.
Alyssa Jaipersaud earned a bachelor of science in industrial and systems engineering with a minor in law and public policy at USC and is also completing a master’s of science in sustainable engineering. She is setting her sights on a full-time role in the sustainability industry either as a consultant or practicing engineer.
Our universe might be chock-full of cosmic wonder, but you can observe only a fraction of astronomical phenomena with the naked eye. Meteor showers, natural fireworks that streak brightly across the night sky, are one of them.
The latest observable meteor shower will be the Lyrids, which has been active since April 14 and is forecast to continue through April 30. The shower reaches its peak April 21 to 22, or Tuesday night into Wednesday morning.
According to NASA, the Lyrids are one of the oldest known meteor showers, and have been enjoyed by stargazers for nearly 3,000 years. Their bright, speedy streaks are caused by the dusty debris from a comet named Thatcher. They appear to spring from the constellation Lyra, which right now can be seen in the eastern sky at night in the Northern Hemisphere.
The moon will be about 27 percent full tonight, appearing as a thick crescent in the sky, according to the American Meteor Society.
To get a hint at when to best watch for the Lyrids, you can use this tool, which relies on data from the Global Meteor Network. It shows fireball activity levels in real time.
And while you gaze at the heavens, keep an eye out for other stray meteors streaking across the night sky. Skywatchers are reporting that the amount of fireballs is double what is usually seen by this point in the year.
Where meteor showers come from
There is a chance you might see a meteor on any given night, but you are most likely to catch one during a shower. Meteor showers are caused by Earth passing through the rubble trailing a comet or asteroid as it swings around the sun. This debris, which can be as small as a grain of sand, leaves behind a glowing stream of light as it burns up in Earth’s atmosphere.
Meteor showers occur around the same time every year and can last for days or weeks. But there is only a small window when each shower is at its peak, which happens when Earth reaches the densest part of the cosmic debris. The peak is the best time to look for a shower. From our point of view on Earth, the meteors will appear to come from the same point in the sky.
The Perseid meteor shower, for example, peaks in mid-August from the constellation Perseus. The Geminids, which occur every December, radiate from the constellation Gemini.
How to watch a meteor shower
Michelle Nichols, the director of public observing at the Adler Planetarium in Chicago, recommends forgoing the use of telescopes or binoculars while watching a meteor shower.
“You just need your eyes and, ideally, a dark sky,” she said.
That’s because meteors can shoot across large swaths of the sky, so observing equipment can limit your field of view.
Some showers are strong enough to produce up to 100 streaks an hour, according to the American Meteor Society, though you probably won’t see that many.
“Almost everybody is under a light-polluted sky,” Ms. Nichols said. “You may think you’re under a dark sky, but in reality, even in a small town, you can have bright lights nearby.”
Planetariums, local astronomy clubs or even maps like this one can help you figure out where to go to escape excessive light. The best conditions for catching a meteor shower are a clear sky with no moon or cloud cover, sometime between midnight and sunrise. (Moonlight affects visibility in the same way as light pollution, washing out fainter sources of light in the sky.) Make sure to give your eyes at least 30 minutes to adjust to seeing in the dark.
Ms. Nichols also recommends wearing layers, even during the summer. “You’re going to be sitting there for quite a while, watching,” she said. “It’s going to get chilly, even in August.”
Bring a cup of cocoa or tea for even more warmth. Then lie back, scan the sky and enjoy the show.
Where weather is least likely to affect your view
Storm systems sweep across the country in early spring, and some will be obscuring skies tonight. But there will still be plenty of areas with clear skies, particularly in parts of the central United States.
“The best spot is going to be in the Upper Midwest,” said Rich Bann, a meteorologist with the Weather Prediction Center.
Minnesota, Wisconsin and Iowa will offer especially good sky-viewing weather and a beach on the Great Lakes could be a nice spot to look up at the stars.
But don’t expect to view the show from Chicago, as Illinois could see some thunderstorms. The weather will be better in the Northern and Central Plains, particularly the eastern Dakotas.
High, wispy clouds are expected over the Ohio and Tennessee Valleys and into parts of the Mid-Atlantic. But, Mr. Bann said, “you may be able to see some shooting stars through thin clouds.”
Clouds will be draped across much of the Southeast and the Northeast, though there could be some clearing in Florida, Georgia, the Carolinas and Virginia. Remember, the meteors could be visible all night long. If you look outside and see clouds, try again later.
Catching the spectacle will be challenging across much of the West, particularly from Washington into Northern California, where a storm system is bringing rain and snow. That system will move east overnight.
There are likely to be some pockets of clear skies at times across southern Nevada, northwest Arizona and southwest Utah, Mr. Bann said.

WASHINGTON — Amid growing national security concerns, the FBI said Tuesday that it has launched a broad investigation in the deaths or disappearances of at least 10 scientists and staff connected to highly sensitive research, including four from the Los Angeles area.
“The FBI is spearheading the effort to look for connections into the missing and deceased scientists. We are working with the Department of Energy, Department of War, and with our state and state and local law enforcement partners to find answers,” the agency said in a statement.
The FBI’s announcement comes after the House Oversight Committee announced that it would investigate reports of the disappearance and deaths of the scientists, sending letters seeking information from the agencies involved in the federal inquiry as well as NASA, which owns the Jet Propulsion Laboratory in La Cañada Flintridge, where three of the missing or dead scientists worked.
“If the reports are accurate, these deaths and disappearances may represent a grave threat to U.S. national security and to U.S. personnel with access to scientific secrets,” Reps. James Comer (R-Ky.), chairman of the committee, and Eric Burlison (R-Mo.) wrote in the letters.
President Trump told reporters last week that he had been briefed on the missing and dead scientists, which he described as “pretty serious stuff.” He said at the time that he expected answers on whether the deaths were connected “in the next week and a half.”
Michael David Hicks, who studied comets and asteroids at JPL, was the first of the scientists who disappeared or died. He died on July 30, 2023, at the age of 59. No cause of death was disclosed.
A year later, JPL physicist Frank Maiwald died at 61, with no cause of death disclosed.
Two other Los Angeles scientists are part of the string of deaths and disappearances.
On June 22, 2025, Monica Jacinto Reza, a materials scientist at JPL, disappeared while on a hike near Mt. Waterman in the San Gabriel Mountains.
On Feb. 16, Caltech astrophysicist Carl Grillmair was fatally shot on the porch of his Llano home. The Los Angeles County Sheriff’s department arrested Freddy Snyder, 29, in connection with the shooting. Snyder had been arrested in December on suspicion of trespassing on Grillmair’s property.
Snyder has been charged with murder.
There is no evidence at this point that the deaths and disappearances, which occurred over a span of four years, are connected.
A spokesperson for NASA, which owns JPL, said in a statement on X that the agency is “coordinating and cooperating with the relevant agencies in relation to the missing scientists.
“At this time, nothing related to NASA indicates a national security threat,” agency spokesperson Bethany Stevens wrote. “The agency is committed to transparency and will provide more information as able.”
Representatives from Caltech, which manages JPL, did not immediately respond to a request for comment.
The sun had barely risen over the Pacific Ocean when a small motorboat carrying a team of Indigenous artisans and Mexican biologists dropped anchor in a rocky cove near Bahías de Huatulco.
Mauro Habacuc Avendaño Luis, one of the craftsmen, was the first to wade to shore. With an agility belying his age, he struck out over the boulders exposed by low tide. Crouching on a slippery ledge pounded by surf, he reached inside a crevice between two rocks. There, lodged among the urchins, was a snail with a knobby gray shell the size of a walnut. The sight might not dazzle tourists who travel here to see humpback whales, but for Mr. Avendaño, 85, these drab little mollusks represent a way of life.
Marine snails in the genus Plicopurpura are sacred to the Mixtec people of Pinotepa de Don Luis, a small town in southwestern Oaxaca. Men like Mr. Avendaño have been sustainably “milking” them for radiant purple dye for at least 1,500 years. The color suffuses Mixtec textiles and spiritual beliefs. Called tixinda, it symbolizes fertility and death, as well as mythic ties between lunar cycles, women and the sea.
The future of these traditions — and the fate of the snails — are uncertain. The mollusks are subject to intense poaching pressure despite federal protections intended to protect them. Fishermen break them (and the other mollusks they eat) open and sell the meat to local restaurants. Tourists who comb the beaches pluck snails off the rocks and toss them aside.
A severe earthquake in 2020 thrust formerly submerged parts of their habitat above sea level, fatally tossing other mollusks in the snail’s food web to the air, and making once inaccessible places more available to poachers.
Decades ago, dense clusters of snails the size of doorknobs were easy to find, according to Mr. Avendaño. “Full of snails,” he said, sweeping a calloused, violet-stained hand across the coves. Now, most of the snails he finds are small, just over an inch, and yield only a few milliliters of dye.
