BIO40A: GENERAL ECOLOGY I. What is Ecology?

This article delves into the realm of ecology, emphasizing the significance of human interactions with the environment. It discusses the distribution and abundance of organisms and their environmental interactions, shedding light on the impact humans have on the ecosystem. The text presents various statistics and historical population data to illustrate the rapid growth of the human population and its consequences on the environment. It underlines the importance of sustainable practices for preserving biodiversity and ecosystem balance in the face of rising human influence.

  23. Human Ecology: - distribution... and abundance... and interactions with the environment some numbers to think about... and maybe remember...

  24. Human Ecology: • - distribution... and abundance... and interactions with the environment • 40% of primary productivity (E) Iowa - arrow pointing to forest fragment

  25. Human Ecology: • - distribution... and abundance... and interactions with the environment • 40% of primary productivity (E) - massive extinction is a predictable consequence 1 10,000,000

  26. Human Ecology: • - distribution... and abundance... and interactions with the environment • 40% of primary productivity (E) - massive extinction is a predictable consequence • 50% of the freshwater on the planet
