• Experts predict that the number of people will continue to grow because better medicine and nutrition allow people to live longer.
• By 2050 the Earth may have as many as 9.6 billion people!
• All those people:– Consume a lot of water, food, building supplies and fossil fuels.– Make a lot of TRASH!
