14-Year-Old Solar Invention: Solar-Powered Jug Purifies Water
A 14-year-old ninth grader from New Hampshire, Deepika Kurup, has earned the title of "America's Top Young Scientist" for inventing a solar-powered jug that is able to transform dirty water into purified water. While visiting India and witnessing the act of young children drinking contaminated water from a dirty pool, Deepika "instantly knew she had to do something about the global water crisis." She had hypothesized that a mixture of chemicals would help to kill waterborne bacteria much faster, cheaper and more portable than current technology.
With her talent in physics, chemistry, biology and mathematics, Deepika had successfully discovered the appropriate amount of chemicals to create photocatalytic rods designed for placement in water bottles and other portable purifying systems. Once activated with sunlight, the bacteria within the contaminated water disappeared and the water became purified in a matter of hours.

Beautiful world falling apart
Natural disasters are often caused by large amounts of air pollution in a short period of time mostly in large cities. Many disasters are formed through natural or human-made chemicals called "smog," which are caused from the factories that manufactures products that undergo through an assembly line consisting of chemical, heat, and wastes, leaving the factory through open air vents and chimneys. This causes large amounts of pollution to our environment, which contaminates the rain to ozone layers uprising global warming. Car exhaust and fossil fuel combustion, as it occurs in motor vehicles, has been identified as the largest contributor to air pollution in the world.
Air pollution also causes numerous health issues leading to many respiratory problems. The lungs of many lives throughout the world become coated with particular matter from excessive exposure to pollution. For example, many people who are already suffering from asthma or any other respiratory issues would have a harder time breathing when there are small particles of toxin and chemicals in the air. Long term exposure of pollution could lead to serious health issues such as emphysema or even cancer. It can especially be severe when exposed to young children as it has a higher chance upon causing childhood asthma and can lead to other serious respiratory symptoms during adulthood.
Here's a video I found that brought my motivation to change this nation's viewpoint towards a new approach but most couldn't help but watch.
