You should aim to grow out your e-commerce career. Companies like Amazon make the greatest difference to climate change as improved logistics benefits the entire supply chain. Mom and pop shops are great for romanticism and NYT hit pieces about the terrors of gentrification and white flight but their logistics are incredibly inefficient compared to efficiencies of scale offered by e-commerce. "Micro" low hanging fruit efforts like data visualization which these comment threads tend to favor make little difference. Grassroots won't solve climate change, you need changes in technologies that allow the emerging economies to no-strings-attached capture the value and benefits of economic growth without the side effects of pollution (that means convincing or forcing institutions like the World Bank/IMF to replace their onerous neoliberal funding requirements with only one: green technologies), you need systematic changes in federal policy, and you need restructuring of company operations to be more efficient. As a software engineer, the most effective thing that you can do is the latter.
