Thanks so much for your thoughtful questions. You're absolutely right, these issues are complex, and it's important (and challenging) to consider the cradle-to-grave impacts of all our purchases. In the case of electrical mowers, battery bulding and disposal are one of those complexities. But with climate change such an urgent problem, we are prioritizing the goal of reducing our greenhouse gas emissions, and because our electricity comes primarily from renewable solar energy, we feel good about choosing electric mowers. As to taller grass, it actually has deeper roots so it can better survive hot, dry conditions, and it also shades the soil, which helps retain moisture. Hope you can visit soon and explore our lawns for yourself! Thanks again for your questions.
