text: i need an attention getter for a persuasive speech on pollution and global warming.? thnx in advance. ne help is help. i heard this on discovery channel....you could word it your own way but....global warming is the number one potential human life killer, and next to it is an aestroid. this is the sad part- we're doing all we can to try and stop a major aestroid that could possibly hit earth, but we're not doing much to stop what we're doing to ourselves- polluting the earth and causing global warming. i thought it was pretty interesting, and true. you could probably re-design it and make it sound better. =] hope i helped.
