cover and seriously increase heat. The good news from a new study based on observations of pollution’s effects on cloud formation is that the effect is mixed and need not be a factor in emissions control.

way its food is grown, does not serve us well. We need to cut down on meat consumption and waste less food. The food we eat should be farmed to increase soil carbon and thus soil fertility; significant acreage must be freed from food production.
