Lead is a old paint that is dangerous to children and people. How is it dangerous? For people it effects water so it makes it bad so you can’t drink it. But we can’t get rid of it because we might not know because some of the pipes are so that’s one problem. Another one is the dust that effects children with lower IQs like, bob had a IQ of 100 . then he was hit by it and know is angry most of the time and has a IQ of 90. It was first made in around 1900s and is a problem in America and New Zealand has had some to and other places may suffer it. It was so bad that even Sesame street did a episode on lead. It was finally banned in 1976. But some people said it was good. How was it good? The only thing it was good at is nothing just nothing this is why it is a big problem in many places. But it may cost at least 200 million’s of dollars to get it done. But we aren’t doing any thing. It might soon be a future problem.
