And to provide more food, fossil fuels are used more often. And more people mean more transportation. This is one of the biggest problem increasing use of fossil fuel. Global warming has observable effects on environment. There are a lot of effects for example: -Ice is melting worldwide. -Sea level rise became faster over the last century. According to the NASA effects that scientists had predicted in the past would result from global climate change are now occurring for example: loss of sea ice, accelerated sea level rise and longer, more intense heat waves.
And if warming continuous, other effects could happen, for instance: -Hurricanes and other storms are likely to become stronger. -Ecosystems will change, some species will become extinct. -Less fresh water will be available. -Floods and droughts will become more common. So, we can contribute to this global cause with personal actions. Our individual efforts are especially significant. We can help immediately by becoming more energy efficient.
