First of all, sorry for not posting for a while. I have been on vacation and was ill after coming back. I am feeling much better now and should start posting again more regularly.
There has been a lot of news this week about how our planet now has 7 billion people. The National Geographic Society has released a new free (for a limited time) app this week which addresses the changes and challenges to our planet with the increase in population.
The app includes interactive maps, videos, photos and articles to explore the impact of a growing population on a planet with limited resources. It is informative and a great complement to any Social Studies curriculum. The statistics used would also make great content for a mathematics lesson.
