Global Warming is caused by humans! Global warming is when the hot weather causes glaciers to melt and seawater levels to rise. In my opinion, I think that the humans caused global warming. The use of vehicles, factories, and electricity release heat trapping gases called greenhouse gases. These greenhouse gases keep the heat from leaving like a regular greenhouse. After the level of greenhouse gases were rising, it slowly became constant but soon enough, the use of fossil fuels are increasing the level of greenhouse gases and it is making the world warmer and making the world a different place. The industry became more advanced and used more fossil fuels and it increased the amount of carbon dioxide.

Humans ride their car and they make new products and they also use fossil fuels for this. The gas most responsible is carbon dioxide and we breathe it out. But the things we do make it worse. Polar bears are becoming extinct due to the ice disappearing. Ice is melting everywhere and the sea level rise became faster over the last century. Many animals migrated to the north or cooler areas due to the warmth of the area they lived in. If this continues, sea levels will increase, animals will be migrating to places they’ve never been before, there will be more natural disasters, and it is likely that there might be more disease. My theory is that humans caused global warming since humans are the ones that made the industry use more fossil fuels and make the world warmer.
