#5 – Global Warming
The steady build up of greenhouse gases such as CO2 and methane in our atmosphere is leading to a rise in global temperatures. This is result is melting polar ice caps, crop death and slowly rising sea levels. There are those who argue that global warming doesn’t exist, but the facts are hard to ignore. If we don’t reduce carbon emissions and turn down the heat, civilisation as we know it could be doomed within a few generations.
