Many people in developing countries have little or no access to electricity. That makes it more difficult for children to study, for medical clinics to keep vaccines cold and to provide emergency care at night, etc. In places like Puerto Rico that have electricity but where there are many problems with the system, a disaster like Hurricane Maria may deprive people of the power they need for months. Micro energy solutions can help people who now live in areas without electric power to have better medical care, more educational opportunities, etc. In places like Puerto Rico they can improve resiliency. It's important to me because I want everyone to have those opportunities and for communities to be resilient. It's vital that we solve the climate crisis, but not by keeping people in energy poverty.

Regenerative agriculture can also help sequester carbon and reduce climate change. It can foster biodiversity. It can reduce the need for pesticides and the hazards to farm workers. It can increase productivity in places where the soil is poor. 

Sustainable communities will vary because they need to fit their surroundings and the cultures of the people who live there. They could range from a village with a handful of families to a mega-city. They should be places where the residents can thrive without harming the natural environment. They won't exist in isolation because they will depend on other communities and rural areas for a variety of goods and services and will provide other goods and services in a balanced way. The ymake good use of their resources with little or no waste. They offer clean air, clean water, safe places to live and work, good food, plenty of social interaction and access to nature, and many opportunities for learning, meaningful work, and healthy recreation. 
Many things need to change to make communities more sustainable. They need to be designed for people rather than for cars, with more public transportation and safer walking and biking. There need to be inviting spaces where neighbors interact and there are trees, birds, etc. as part of everyone's everyday life. We need to create less waste and find ways to reuse and recycle more and to use energy more efficiently. We need to get away from fossil fuels and other polluting energy sources and use more renewable energy, much of which may be generated in the community. Most communities wouldn't grow most of their own food but home gardens, community gardens, urban farms, etc. could be very helpful in getting fresh, healthy food to the community's residents.

I've gotten a number of likes and retweets on Twitter, but not many comments other than asking about educating boys.

I think the biggest needs are for better public transportation and for cities to be more bike and walker friendly. In my area that means we need more funding and more funding stability for the public transit system. That funding needs to make service more reliable and to improve service to areas with many low-income residents while keeping fares affordable. We can advocate for that with our local, state, and federal governments.
