This week I came across a map from Alessa Berg and the team at Top Tier Impact. It shows more than 160 startups using biology to make the things we use every day: food proteins, plastics, dyes, building materials, textiles and chemicals. Some use fermentation, some use algae and some use enzymes. All of them take their cues from nature. It’s a remarkable list, and I’ll admit it made me a little emotional.
