States, including Colorado, restrict the use of rain barrels. A water law scholar says a better way to conserve is reduce waste from big – and powerful – water users.
Cuban farming is a model of agroecology – growing food without heavy use of fossil fuel or chemicals. But closer relations with the U.S. could push Cuba back toward large-scale industrial farming.
In 2015, gas prices fell below $2 per gallon in Moscow Mills, Missouri. The trend of low gas prices across the United States delay a signature Obama proposal to reduce emissions from cars and trucks.

Faced with stringent fuel economy standards but cheap gas, automakers may seek to delay CAFE rules. What’s the best way to reevaluate these emissions-cutting rules?
Many women in developing countries spend hours every day fetching water for their families. Reducing the burden of water work will improve their health and welfare.
Droughts have traditionally yielded good vintages in France, but changing conditions are forcing wine growers to adapt.

Cheap gas is traditionally a boost for the U.S. economy but this time the economy could be badly hurt because of the domestic drilling boom and financial bets made by the oil & gas industry.
Chlorine needed?

How did lead poisoning become a persistent threat in U.S. cities? Lead paint and slumlords played key roles, but so did postwar housing policies that trapped minorities in crumbling inner cities.
If the U.S. moved to electric vehicles, there would be a substantial cut in air pollution – and health benefits to go with it.

Global warming is often seen as a problem for future generations, but focusing on the immediate – and substantial – health benefits of clean energy can change public perception of climate change.
Will the world resort to ‘solar radiation management’ to slow the Earth’s heating?

Yes, we blunt the effects of climate change by getting off fossil fuels. But countries’ most ambitious targets imply use of climate engineering schemes – and that discussion should be done in public.

Scientists say they’ve answered a long-held question of Darwin’s on why islands are so productive – an important step toward planning protections against the effects of climate change.
In addition to the Clean Power Act policy for climate change, the Supreme Court will be hearing cases on the extent of protections under the Clean Water Act.
