Detailed explanation-1: -Global warming, toxic waste, water and air pollution, acid rain, and shrinking energy supplies are frightening challenges that may threaten our future if we do not face up to them. Global Environmental Challenges provides important information and gives us hope about the environment.

Detailed explanation-2: -The main threats of climate change, stemming from the rising temperature of Earth’s atmosphere include rising sea levels, ecosystem collapse and more frequent and severe weather. Rising temperatures from human-caused greenhouse gas emissions affects planet-wide systems in various ways.

Detailed explanation-3: -Climate change is already happening: temperatures are rising, drought and wild fires are starting to occur more frequently, rainfall patterns are shifting, glaciers and snow are melting and the global mean sea level is rising.

Detailed explanation-4: -Most industrial processes, including animal agriculture, travel, and manufacturing, create CO2 emissions. CO2 and other greenhouse gases absorb heat coming out of Earth towards space. Therefore, heat that the planet would’ve formerly lost to space is instead kept within our atmosphere, warming our planet.
