Answer:
1. About 90% of wildfires in the United States are started by humans.
2. In a non-human world, wildfires would mostly be started by lightning strikes.
3. On average, more than 100,000 wildfires clear 4-5 million acres (1.6-2 million hectares) of land in the U.S. every year. In recent years, wildfires have burned up to 9 million acres (3.6 million hectares) of land.
4. It takes an average of 2-4 years after a wildfire before reforestation efforts can begin. Saplings simply wouldn’t survive until the soil has begun to naturally replenish, can absorb water, and can support new life. It also takes time to mobilize resources for large-scale reforestation.
5. Increases in the cost of battling active wildfires have greatly reduced the budgets available for prevention, which creates a domino effect of worsening conditions.
6. Climate change, as predicted, is fueling longer, stronger, and quicker-to-start wildfires.

Answer:
Greyfields are vacant commercial spaces and empty shopping malls.
Explanation:
Greyfields are basically large objects, usually, ones that were accomodating commercial entities like shopping malls. Because of multiple factors, those shopping malls and other types of commercial entities have closed, mostly because they have been outcompeted by more modern malls that were more attractive to the consumers.
Because they tend to be surrounded by asphalt, and the concrete dominates in the structure, they have been given the name ''grayfields''. Even though they stay unused in the urban landscape, they often offer every condition for a mall to be restarted, as the facilities are there, they tend to have a good location and are well connected with infrastructure.
