G7 nations have contaminated the earth and have seriously disturbed the earth, because G7 nations are the most powerful industrialised nations, which have seriously led to contaminated air, air pollution, earthquake, earth tremor, volcanic eruption, flood and many other earth hazards.
And all these earth hazards has led to shortage of life. United States and China are major industrialised nations that have seriously disturb the earth, destroying the earth, destroy the air we breath in for their own political benefit.
United States has been disturbing the earth long way back before Chinese development. And that's why climate change must be executed, that's why all nations must support climate change.
Current United States president "Donald Trump" has said there is nothing called climate change.. He doesn't know the meaning of climate change.. He is withdrawing United States from the mission of making the earth a better place for me and you and generations to come.
All G7 nations must support climate change because they are destroying the earth.
