The earth is literally melting. Global warming is causing the earth to overheat. This is the result of emissions released into the atmosphere through greenhouse gases and human activity. There are numerous reasons as to why this is happening and causing the earth to increase in temperature. Global warming occurs all over the world, and has been happening for many years now. Food shortages, contaminated water, extreme weather, and deadly heat threaten human health because of the rising temperatures. To this day, global warming has not only affected humans, but has
