Waste not , want not

If you think we were the first ones to come up with keep - it - clean campaigns and recycling , think again! We are certainly not the first ones to fuss about cleanliness nor the only ones to recycle waste. Early humans used things found in the environment , and after they were done using or consuming them , they made new things out of them . Man ate the meat of animals and shaped the leftover bones into tools and weapons and thus humans began "recycling" or using trash and waste to make new materials from old ones.
