Behind me is the city that we live in. It may seem nice, but there is one huge, growing problem affecting it, and that is Global warming.
Let me explain it to you. Global warming is the cause of many things, but mainly, melting of glaciers, rising sea levels and collapsing ecosystems. It is being caused by an increase in greenhouse gases (carbon dioxide, methane and nitrous oxide).
Global warming has already increased heat waves, seal levels and average temperatures. if you think this is bad, it will only get worse if we keep living the way we currently are.
