"Greenhouse Effect, Human Crisis"

The results of global climate warming are catastrophic: glaciers melt, sea levels rise, causing coastal tidal wetlands, mangroves and coral reefs, etc. Loss of ecological groups, coastal erosion, seawater intrusion into coastal underground freshwater layers, coastal land salinization, etc. This has resulted in an imbalance in the natural ecological environment of coasts, estuaries, and bays, and has brought great disaster to the ecological environment of the coastal zone. Not only that, it will also increase the water area, increase the degree and severity of storm impacts, and shorten the life of reservoir dams. Rising temperatures may melt the ice and snow in the Antarctic Peninsula and the Arctic Ocean, and polar bears and walruses will gradually become extinct. Eventually, the earth on which human beings live becomes uninhabitable.
