High temperatures threaten our health, environment, and everything that surrounds us. High water temperatures stress coral reefs, which makes already fragile underwater environments even less hospitable for undersea species. Many hazardous bacteria reproduce much faster at higher temperatures, making many more places in the world a haven for diseases that bring death and destruction to hospitable places. Global warming has already begun and there is nothing that we can do now to decrease its effect substantially and immediately. However, over time, if we work together, we will be able to fight this problem and restore the devastating effects of global warming.
