Chapters,layout etc

As the theme of my book is urgency, i want the images to somehow demonstrate this either through the images themselves or the media used to create them? The environmental issues i want to focus on provides me with a huge area to work on so i have broken them down into more digestable chapters which are as follows:

within each chapter are sub topics from which i shall create my imagery

-Overuse of Resources (Agricultural,deforestation,fossilfuels,irrigation,land degredation,over illumination,overpopulation,resource depletion,water crisis)

-Climate change (Global warming, ecological crisis, endagered species,air pollution,software,soil erosion)

-Conservation (Animals,resources,recycling,waste)

-Other (Light pollution,over illuminaton,noise pollution,genetic engineering,traffic,contamination)
