  5. The United Nations Framework Convention on Climate C

Environmental issues

  1. Environmental issues refer to the harmful effects of human activities on the natural environment.
  2. Global warming is caused by the increased concentration of greenhouse gases in the atmosphere, leading to rising temperatures.
  3. Climate change results in altered weather patterns, rising sea levels, and extreme weather events.
  4. Deforestation is the large-scale removal of forests, causing loss of biodiversity and disruption of ecosystems.
  5. Air pollution, caused
