The Rise of the “Bike Bus” Movement
01 On Earth Day* 2022, Sam Balto, a physical education teacher in Portland, convinced a few
02 dozen parents to send their kids to school on their bikes and posted the first in a series of videos
03 that turned his “bike bus” into a viral sensation. Balto has continued documenting his weekly
04 bike buses with joyous videos that show students rolling to school while he blasts music from an
05 eclectic collection of artists, including AC/DC, Metallica, and OneRepublic. Over time, these
06 boisterous bike buses have grown to more than 150 kids. “The more these kids practice riding
07 bikes, the more confident they become. And now they want to keep riding on non-bike bus days,
08 and even on rainy days!” said Balto.
09 Balto’s bike bus is much more than a fad. His TikTok and Twitter videos have raked in
10 millions of views, inspiring similar initiatives in New York, New Jersey, Florida, Utah, Ohio, and
11 Texas. Bike buses previously existed in European cities such as Barcelona and London, but new
12 ones in cities like Cape Town are now joining the trend. Nancy Pullen-Seufert, the director of the
13 National Center for Safe Routes to School, said biking and walking to school have myriad benefits,
14 including “improving air quality, improving safety for walkers and bicyclists, increasing physical
15 activity, and making it easier for school buses and others who can’t actively travel to school to
16 arrive to school on time.”
17 Balto has also triggered real political change by working with lawmakers to pass a so-called
18 “Bike Bus Bill”, that was signed into law by Oregon Governor Tina Kotek in August. “The bill
19 brings flexibility so school districts can now use student transportation funds, which were
20 previously only for school buses, to pay for crossing guards or adults to lead walking school buses
21 or bike buses. It’s awesome.” Balto said. And he is not the only bike bus leader driving positive
22 change in Oregon… Last year, Megan Ramey, who has been organizing a bike bus ___ 2020, was
23 named the Safe Routes to School Manager at Hood River County School District and since then,
24 she has secured nearly $11 million in funding to make it safer for kids to walk and bike to school.
25 “I feel like I'm in a cash-grabbing machine. We just got $7 million to create an off-road trail to
26 the high school. This means kids will be able to bike to high school on a green trail instead of a
27 car-centered road,” said Ramey.
28 Nearly 90% of kids walked to school in 1969. Half a century later, in 2017, that number
29 had fallen to just 10%. That year, a third of students took the school bus and more than half
30 were driven in a private vehicle. This has led to more pollution, with researchers finding that
31 toxic car fumes have an adverse effect on attention, reasoning, and academic performance
32 among school children. In New York, the Open Schools Program has helped increase biking and
33 walking in the 65 schools that restricted traffic during drop-off and pick-up times this year, said
34 Sabina Sethi Unni, who works at Open Plans, a non-profit that supports the shift to walkable
35 cities. “This program makes kids more comfortable with walking and biking at a young age. When
36 they get older, they will be cyclists instead of car users,” said Unni.

Pollution
Thick black smoke curling out of smokestacks, horrible-tasting chemicals in your drinking water, pesticides in your food - these are examples of pollution. Pollution is any contamination of the environment which causes harm to the environment or the inhabitants of the environment. There are many kinds of pollution, and there are many pollutants. Some obvious kinds of pollution are pollution of the air, soil, and water. Some less obvious, or less salient kinds of pollution are radioactive, noise, light pollution, and green-house gasses.
Air pollution can be caused by particles, liquids, or gases that make the air harmful to breathe. There are two main types of air pollution: primary and secondary. Primary pollutants enter the air directly, like smoke from factories and car exhaust. Secondary pollutants are chemicals that mix together to pollute the air, like mixtures of emissions, or waste output, from vehicles and factory smoke that change to form more dangerous pollutants in the air and sunlight.
Soil pollution can be caused by pesticides, leakage..........................chemical tanks, oil spills, and other chemicals..........................get into the soil by dumping or accidental contamination. Soil pollution can also cause water pollution.............................underground water becomes contaminated by coming.............................contact with the polluted soil.
Water pollution can be caused by waste products, sewage, oil spills, and litter in streams, rivers, lakes, and oceans. Some scientists believe that water pollution is the largest cause of death and disease in the world, causing about 14,000 deaths in the world each day.
Radioactive pollution can be caused by leaks or spills of radioactive materials. These materials can come from medical sources, nuclear power plants, or laboratories which handle radioactive materials. Air, soil, and water can be polluted by radioactivity. It can cause damage to animals, both internally and externally, by eating, drinking, or touching it. It can cause birth defects and genetic problems. It can cause certain cancers and other deadly diseases.
Noise pollution can be caused by vehicle, aircraft, and industrial noise. It can also be caused by military or experimental sonar. Noise has health effects on people and animals. In people, it can cause high blood pressure, heart problems, sleep disturbances, and hearing problems. In animals, it can cause communication, reproductive, and navigation problems – they have difficulty finding their direction. Sonar has even caused whales to beach themselves because they respond to the sonar as if it were another whale.
Light pollution can be caused by advertising signs, stadium and city lighting, and other artificial lighting (like the light caused by night traffic). Artificial lighting has health effects on humans and animals. In people, it can cause high blood pressure and affect sleeping and waking rhythms and immunity. It might be a factor in some cancers, such as breast cancer. In animals, it can affect sleeping and waking rhythms, navigation, and reproduction.
In addition, greenhouse gases have caused a warming effect on the earth’s climate. The greenhouse gases are water vapor, carbon dioxide, methane, and ozone. They are naturally–occurring gases in the atmosphere, but human activity has increased their concentration in the atmosphere. For example, the levels of carbon dioxide (CO2) in the atmosphere have risen due to the burning of fossil fuels. The effect is a rise in global temperatures. The higher temperatures cause the melting of glaciers, a rise in the water level of oceans, and the disruption of both land and marine life, including that of humans. Although carbon dioxide is necessary for plants to survive, it is also considered to be a kind of pollution because high levels of carbon dioxide have caused the oceans to become more acidic.
It is not possible for anyone to predict the exact timing and effects of global pollution and global climate change brought about by pollution. There is general agreement by scientists that the global climate will continue to change, that the intensity of weather effects will continue to increase, and that some species of animals will become extinct. There is also general agreement, or consensus, that humans need to take steps to reduce emissions of waste products and greenhouse gases into the atmosphere, make adaptations to the changes that are occurring, and figure out ways of reversing the trends of pollution and global warming.
