The most important environmental issue of our time is climate change. Climate change is caused by human activities that release greenhouse gases into the atmosphere, which trap heat and cause temperatures to rise. This causes extreme weather events such as hurricanes, floods, droughts, and wildfires, as well as changes in ecosystems and habitats. These effects can have a negative impact on the environment, economies, and people’s lives.
