Americans have been sending garbage to landfills for almost 100 years.Since the first one opened in Fresno, California in 1937, today the U.S. hauls about 268 million tons of trash to thousands of active landfills each year.However, it's not without debate over whether these dumps are our best option.A lot of our nation's garbage starts in the home. According to the EPA, paper accounts for 25 percent, food is 15 percent of the waste and plastic amounts to 13 percent.The journey to the landfill involves a few pitstops. After garbage collectors pick up the trash, they take it to sorting facilities, where machines and people in full hazmat suits separate everything. This can be time-consuming, and dangerous.Recyclables are sent off to be reused, and trash is either incinerated to create clean, renewable energy or taken to the landfillLandfill operators follow strict guidelines to help make sure their facilities don't cause any harm. They lay a base layer, several feet deep, below any trash. It's made up of materials like clay, minerals, and charcoal, which help make sure nothing seeps into the ground or water. Trash is strategically layered on top and then buried to help seal it off.In some cases, the sealed pile is covered in cement or asphalt and developed in homes or businesses. But those sealed-off piles still give off greenhouse gas emissions and fumes that can harm the environment and peoples' health.Some companies use technology to reduce emissions by capturing them and turning them into renewable energies. Researchers say even with that technology landfills can still pose hazards.One way to reduce the mountains of trash in landfills is to recycle.Americans throw away .5 billion in recyclable materials each year, including paper, plastic, cardboard, and aluminum products. 1817

An attorney for the former school resource officer at Marjory Stoneman Douglas High School defended the officer's response to the Parkland shooting, saying in a statement Monday that Scot Peterson acted appropriately during the shooting."Let there be no mistake, Mr. Peterson wishes that he could have prevented the untimely passing of the seventeen victims on that day, and his heart goes out to the families of the victims in their time of need," the statement from attorney Joseph DiRuzzo III says."However, the allegations that Mr. Peterson was a coward and that his performance, under the circumstances, failed to meet the standards of police officers are patently untrue."Peterson resigned on Thursday after Broward County Sheriff Scott Israel suspended Peterson without pay for allegedly waiting outside the Florida school as the shooting unfolded."What I saw was a deputy arrive at the west side of building 12, take up a position," Israel said of the footage. "And he never went in."But, in a statement, DiRuzzo said that Israel's statement "is, at best, gross over-simplification" of what happened when a shooter killed 17 people at the Florida school.Peterson initially ran toward the 1200 building where the shooting took place, and then he "heard gunshots but believed that those gunshots were originating from outside of any of the buildings on the school campus," according to DiRuzzo.The Broward County Sheriff's Office, or BSO, "trains its officers that in the event of outdoor gunfire one is to seek cover and assess the situation in order to communicate what one observes to other law enforcement," DiRuzzo said.Peterson acted consistent with his training and "took up a tactical position between the 700-800 buildings corridor/corner," Peterson said. He was the first officer to advise dispatch that he heard shots fired, and he initiated a "Code Red" to lock down the campus, according to the statement."Radio transmissions indicated that there was a gunshot victim in the area of the football field," which served to confirm Mr. Peterson's belief "that the shooter, or shooters, were outside," according to DiRuzzo's statement.Trump says Peterson 'choked' 2185

An educational platform that was created to help the nation's teacher shortage is now helping schools backfill during the pandemic."Elevate K-12" offers live instruction, and some districts say it's filling in the gaps for students.Eighth-grade science looks a lot different these days, at least in Louisiana's Caddo Parish Public Schools."We really are almost the districts in one," Caddo Parish Public Schools Chief Academic Officer Keith Burton said.Of the district's 61 schools, 65% are Title 1 schools, meaning they receive federal funds for having large concentrations of low-income students.While the district also has magnet and gate programs, there were some instructional gaps."We really struggled in the area, as most districts do around the nation with needing enough mathematics teachers — especially around the middle and high school area — as well as science and foreign language teachers," Burton said.The district discovered Elevate K-12 two years ago and now use their live teachers for 67 periods."Anywhere from seventh-grade math to Spanish II, Algebra II, in about every corner of our district," Burton said."If you look at the entire U.S. K-12 population, there are 58 million students, of which 50.8 million are in the public school system," said Elevate K-12 CEO and founder Shaily Baranwal. "In that, about 22 million are low-income. The teacher shortage problem specifically plagues the low-income neighborhoods. We work with some states in some zip codes where they can't even find a grade four math teacher."Baranwal grew up in Mumbai, and Elevate K-12 was born out of a business school project."I'm that one Indian that rebelled and said I do not want to do engineering," Baranwal said. "I've always followed my heart, followed my passion. I'm an extreme non-conformist, so I did not follow that path and got an early childhood teaching certification. I then worked as a preschool teacher in India, came to the U.S. to Michigan to get my MBA."She says she created the platform to solve one problem: the nation's teacher shortage."One of the school districts we work with in Georgia — when I was talking to the head of talent there, they did not have an Algebra I teacher for the last four years," Baranwal said. "So, what they had to do was they took the local priest and made the local priest get an Algebra I secondary certification so the local priest could then teach the class."Elevate K-12 now helps large and small school districts around the country, and it just so happens to be in a unique position to help those who have gaps because of the COVID-19 pandemic."This solution was not created to solve a COVID problem," Baranwal said. "The teacher shortage problem has been plaguing the U.S. K112 schools and districts and specifically the low-income neighborhoods for years. What COVID has done for us is accelerated the entire acceptance of live streaming instruction as a solution."They have a network of more than 2,000 teachers, and more than 300 are actively teaching now. All are certified and based in the U.S."We are shaking up the K-12 antiquated system in making people realize that you should not offer a class like German or cybersecurity or science or math, just because you don't have a teacher," Baranwal said. "Take those barriers away and use live-streaming instruction so the teacher can be anywhere in the country. Your kids can be where they are and still learning in a highly engaging format."Burton says Caddo Public Schools hasn't had to use it for reasons related to the COVID-19 pandemic as of yet, but they're in a position to, should they need it.He added that the students adjusted quickly, and some even prefer personal and private teacher-student interaction."Now I'm able to leave those classrooms and see students engaged see students learning," Burton said. "Many times, students are saying I'm having conversations with a teacher in Colorado or North Carolina, and those students are loving it. They really are." 3992

Americans are trying to form better financial habits in light of the recession, building emergency savings and paying down debt.However, many are finding savings accounts are now returning next to nothing in interest. That's because of the Federal Reserve's decision to keep interest rates low.Rates that were over 2.5% a year ago are down to under 1% now. But there are some other accounts that can get you a better return.“Something known as a rewards checking account might be a better option,” said Greg McBride, Chief Financial Analyst at Bankrate.com. “These are accounts that typically pay higher yields, higher than even online savings accounts, you might find 1.5, 2, 2.5%, but you have to meet certain qualifications each month to earn that deal.”Rewards checking accounts typically are offered by smaller community banks and credit unions. They usually come with monthly requirements though, like direct deposit, online bill pay, enrolling in e-statements, and using your debit card a certain amount of times. But those are things many people already use.In terms of saving versus paying down debt now, experts say to save.“That's really critical. No one knows what’s going to happen down the road in terms of jobs or income, so having some money put away will help you sleep at night,” said McBride.Just to give you an idea, you could make by saving around ,000 a year at 3% interest rate, which a rewards account might pay.That’s compared to just 60 cents in an average savings account, which only has about a .06% interest rate. 1556
