Knowing how conventional cotton is grown and denim is made, always-a-better-way outdoor apparel brand Patagonia has set out to change the industry. The company has partnered with chemical company Archroma on a new denim collection, launched this week - which is Fair Trade certified and said to use 84 percent less water, 30 percent less energy and 25 percent less CO2 compared to conventional denim dyeing processes - as well as a campaign telling us all about it.

With the world's coral reefs increasingly threatened by warmer and more acidic seas, scientists are selectively breeding corals to create species with the best chance to survive in the coming century and beyond. Are genetically modified corals next?

The Obama administration's rule leans heavily on renewable energy to meet its goal to reduce carbon dioxide emissions by 32 percent by 2030, which is an increase of 2 percentage points from the draft it released in the summer of 2014. While states have two additional years until they must begin cutting emissions - 2022 instead of 2020 - they are expected to start devising ways to improve their environments, which will focus on shifting to cleaner burning fuels and away from carbon-heavy ones. "The trend we are on will get us there," says Rob Gramlich, senior vice president for government affairs at the American Wind Energy Association, in a phone interview. "As the nation moves from coal to gas, and as it adds more wind, solar and energy efficiency, we will reach that 32 percent target."

President Barack Obama moved Saturday to tighten U.S. rules on sales of ivory from African elephants, aiming to show progress on conservation as he began a trip to the region.

The proposed Pebble Mine in southwestern Alaska is a project of almost unfathomable scale. The Pebble Limited Partnership intends to excavate a thick layer of ore - nearly a mile deep in places - containing an estimated 81 billion pounds of copper, 5.6 billion pounds of molybdenum, and 107 million ounces of gold. The mine would cover 28 square miles and require the construction of the world's largest earthen dam - 700 feet high and several miles long - to hold back a 10-square-mile containment pond filled with up to 2.5 billion tons of sulfide-laden mine waste. All this would be built not only in an active seismic region, but also in one of the most unspoiled and breathtaking places on the planet - the headwaters of Bristol Bay, home to the world's most productive salmon fishery. Composed of tundra plain, mountain ranges, hundreds of rivers, and thousands of lakes, the greater Bristol Bay region encompasses five national parks and wildlife refuges, and one of the largest state parks in the U.S.

Nike identified water inadequacy and resource cost volatility among the risks, opportunities and challenges surrounding its business. This became the driving force behind the forging of the relationship between Nike and Dutch award-winning startup DyeCoo, a Dutch company that launched the world's first ever industrial dyeing machine that uses high pressure carbon dioxide (CO2) as a replacement for water to dye polyester.
