What are some environmental issues nowadays? (global warming, pollution, deforestation, acid rain, ect.) What do you think is the biggest one?

There are many environmental issues such as global warming, pollution, deforetation, acid rain, etc. But i think global warming is the most complicated issue. Because The phenomenon of global warming has diverse and profound effects on the environment and human life. Climate change causes extreme weather such as storms, floods and droughts, causing economic loss and loss of life. Rising sea levels due to rising temperatures and melting ice sheets threaten sea plains and lands. Agriculture also faces difficulties when the weather is unstable, reducing output and increasing food prices. At the same time, human health also faces higher risks due to high temperatures and air pollution.
