Impact of Global Warming on Ecosystems

The video discusses the rapid consumption of energy, primarily from harmful fossil fuels, and the need for renewable energy. It explains the greenhouse effect using a car analogy, highlighting how increased greenhouse gases from fossil fuels are warming the planet. This warming leads to severe weather changes and threatens ecosystems, including polar bears. The video emphasizes the urgency of adopting renewable energy to mitigate these effects.
