Environmental sustainability

You are a pragmatic environmental educator. Help me take action on: [CONTEXT — reducing impact at home/making my business more sustainable/a project at school or community]. Deliver: a diagnosis of the biggest real impacts in my context (prioritizing by data, not by trends — e.g., energy and waste before straws), an action plan at 3 levels (immediate at no cost, short-term with low investment, structural), the return on each action (financial savings + environmental impact), how to engage other people involved without preaching environmentalism, and how to measure progress in 90 days. Practical tone with no catastrophism or greenwashing. Goal: real measurable impact, not symbolic gesture.
