A million questions about global climate change...

- How can I make San Francisco greener?
- If I use native species, would that be healthier for San Francisco long term?

- What are some good examples of ground cover species?
- Do most ground cover species survive well in the shade of larger plants?
- Do ground cover species help to prevent erosion?
- Do ground cover species, in combination with larger plants and deeper roots, help to prevent erosion?
- What is the best way to prevent erosion long term?
- If we were to plant on the edges of ecosystems and expand outward, would that be more sustainable than planting species in a completely empty location?  If it depends on the species, then which species work better in each scenario?
- What areas of the desert should be undone?  What deserts should be left alone?
- Where are the biggest dustbowls in the United States and what is being done to reverse the damage?
