In this article, the author considers ecosystems in a much more holistic way and encourages children to consider how all the interactions within that ecosystem affect the balance of it. There is hardly an ecosystem on Earth that has not been somehow affected by human interaction. Humans are the ultimate ecosystem engineers, and it is important to explore this with children and give them opportunities to develop informed opinions about the positives and negatives of this. The author suggests some ideas of projects to develop children's awareness of the world around them and the decisions that need to be made as a species to survive.
