The purpose of this experiment is to examine the effects of salt on seed germination, plant growth, and flower production. Salt is used all across the US for deicing roads during the winter which can be transported to roadside vegetation. Salinity is known to reduce the growth of glycophytes (salt-s...
All the test solutions were measured for Carbon Dioxide release every five minutes for one hour. ... It did not stop producing Carbon Dioxide, rather, it had reached a peak at the end of the hour of .94ml/mimute of Carbon Dioxide (Graph I). ... Through the hour, the Carbon Dioxide that was produced never reached a peak as it did in glacatose; rather, it had a steady rate of production of .014ml/minute of Carbon Dioxide. ...

Over the past several years, temperatures around the world kept rising. Sometimes it's unbearable for people on this planet. "The temperature during an eight-day heat wave in Chicago in July 1995 hovered around 100 degrees Fahrenheit. High levels of humidity made the air feel even hotter, creating an almost unbearable and, ultimately, fatal environment. 556 number of deaths was attributed to the heat, which struck the elderly" ("Issues and Controversies: Global Warming "). Until human populations soared and began burning fossil fuels, greenhouse gases remained in relative balance. ...
