The most significant environmental challenge that humanity currently faces is climate change. Climate change is caused primarily by the burning of fossil fuels, resulting in the emission of greenhouse gases such as carbon dioxide and methane. This climate change is causing global temperatures to rise, leading to extreme weather events such as floods and droughts, sea level rise, and ocean acidification. In addition, climate change is having drastic impacts on global ecosystems, leading to mass species extinction. In order to protect the planet it is important for governments and individuals to take action to reduce their carbon emissions.
