The global warming has been a great issue for all the human kind. Ice are melting everywhere at an accelerating rate. And more and more species are extinguishing frome the earth. What can we do to prevent it from being worse? what can we do to arouse the sttention of this issue? I know some good solgans. they did help a lot, but still need our help. do you have any good ideas or slogans that can help?
