We look at human impacts on ecosystems, the role of humans and how the development of farming and hunting has impacted on ecosystems. This powerpoint has several key hunter gatherer weapons and their use and an accompanying worksheet. I taught ecosystems, food chains and webs, then posed the question, where do humans belong? We talked about our lack of skill in hand to hand hunting against the animals we eat. We then looked back into human impacts as food became 'easier to get'. Including farming, extinctions, plastics in supermarkets etc.
