What are the types of environmental problems/who deals most with them?

There are various types of environmental problems, ranging from air pollution to deforestation. The most common type of environmental problem is the human impact on the environment, which includes such issues as climate change, air pollution, water pollution, land degradation, overpopulation and the introduction of invasive species. The most prominent group dealing with these types of problems is governments and international bodies, such as the United Nations and the World Resources Institute. These institutions are responsible for setting policies and regulations to combat environmental problems, and they also coordinate research and share information on environmental threats and trends. Non-governmental organizations and private companies also play a role in addressing environmental issues, usually through conservation efforts, research, and advocacy. Finally, individuals can also make a difference by educating themselves on environmental issues and taking conservation-oriented actions such as reducing energy consumption and choosing more sustainable products.
