Clean energy, waste disposal, air pollution, and climate change are polarizing subjects worth discussion. Melting glaciers, rising sea levels, warmer oceans, and changing wind patterns are all indicators that global warming is a real concern. One of the most urgent consequences of climate change is unhealthy air. Millions of people die unnecessarily each year as a result of toxic air pollution. To mitigate landfill waste and air pollution, countries like Sweden and the Netherlands have taken innovative steps toward creating a more sustainable planet.
