Buy organic cotton and you’ll help transform lives, communities, the environment, the world…

The textiles industry is revolting. It causes 10% of the planet’s carbon footprint, while the dyeing and treatment of textiles is responsible for 17% of all industrial water pollution. Cotton uses 3% of global water, and the damage from cotton farming is $83bn. This eco cost is partially offset by longevity: a bath sheet should be in service for 10 years. I’m serious. So I was distressed to hear that 4,000 Wimbledon towels had been nicked as souvenirs by players. I make an appeal to Djokovic, Williams, Murray et al: please keep them towels in service.

Every time you make a purchasing decision, you’re also making a production decision, so when you come to replace towels and bed linen, go for organic. Currently, just 1% of the world’s cotton is organic. Let’s get that higher. Growing organic cotton is a far more responsible use of farmable land and fresh water, than conventional. The Textile Exchange surveyed 82,000 hectares of land in 2014 and found reduced global-warming potential, lower soil erosion, less water use and less energy demand from organic, as opposed to conventional, cotton growers.

Paula Kahumbu: The conviction and sentencing of Feisal Mohammed Ali sends a message to poachers and traffickers that the net is closing around them

On Friday, a Mombasa law court sentenced Feisal Mohammed Ali to 20 years in jail after finding him guilty of ivory illegal possession of ivory worth 44 million shillings (US $440,000). The court also imposed a fine of 20 million shillings.

This landmark ruling by the Kenyan court is the end of a long story that began with the seizure of 2 tonnes of ivory at Fuji Motors car yard in Mombasa in June 2014.

Achvaneran, Highlands The only recourse was to do a ‘wildlife watch’, ignoring everything else and concentrating solely on what was around in nature

Walking down the garden to my study I could hear a single male curlew calling from the field. They had bred down below the house, but his partner and their offspring had already gone to the coast.

I eased open the curtains in front of my desk and knew that with the warm sunshine it would be difficult to concentrate on writing. The only recourse was to do what I call a “wildlife watch”, concentrating solely on what was around in nature. Out came the telephone link to the house, the binoculars, camera and notebook, and I was set.

Identifying the microbes and knowing their distribution will be one more important step in understanding the carbon cycle, and of monitoring and predicting emissions of greenhouse gases.

Reports of health effects from wind farms do not match where wind farms are found. Other factors are at play. Fiona Crichton explains.

At UNSW, researchers are investigating the economics and practicalities of e-waste recycling saving the embodied energy, and keeping rare resources, skills and jobs in Australia.

A small bog in Lancashire is once again home to a rare species of butterfly, for the first time in 100 years.

Imagine Melbourne without the bay, Perth without the beach and Sydney without the Harbour. Imagine if there was no standing water in your town.

There are certain environmental benefits only farmers can provide; a weakened subsidy system will dissuade their efforts

It was perhaps the most significant pre-Brexit tie between Britain and the European Union: for decades, the Common Agricultural Policy (CAP) has provided supportive subsidies to EU farmers, consuming 40% of the EU’s annual budget in the process, almost £3bn of which went to the United Kingdom each year.

CAP’s system of subsidies works to incentivise farmers to produce more food, so the EU can remain food secure, and also funds those who set aside land for environmental protection instead of cultivation. But CAP’s inability to fully deliver on its ambitious goals has made it a controversial policy, one that both bolstered and undermined Britain’s relations with the EU.

US presidential candidate said planning conditions associated with Aberdeenshire project had not been satisfied

Donald Trump has vowed to continue fighting the windfarm development off the coast from his Aberdeenshire golf course, branding the project an act of “public vandalism”.

The US presidential candidate returned to the fray after Swedish energy company Vattenfall confirmed on Thursday that it is going ahead with its £300m investment, despite last month’s EU referendum vote.

A dolphin that was sunburned while stranded out of water on mudflats for 24 hours in May appears to be recovering from its injuries.

Decompression computers worn by recreational and commercial divers provides accurate data, study shows

Millions of holidaying scuba divers are able to become citizen scientists and take vital measurements of ocean temperatures, which are being driven up by climate change.

More than 90% of the heat trapped by global warming goes into oceans, where it drives hurricanes and disrupts fish stocks. Satellites can measure surface temperature when there are no clouds, but getting data from below the surface is much harder and more expensive.

Delamere Forest, Cheshire Red and blue damsels drift around me like filaments on the breeze but I am here to see a rarer species: the white-faced darter

I skirt the edge of lower Doolittle Moss, in Delamere Forest, treading through soft peaty soil and batting away the pungent bracken that has grown almost as tall as me. Hard green fruit are starting to appear on the brambles, and bumblebees are making the most of the last blossoms.

Surrounded by forest on all sides, the moss is black acidic water devoid of fish. Not the least bit inviting, even as the temperature climbs. But it is a boggy beauty spot in its own right. Half submerged islands of vivid lime-green sphagnum moss break the surface. Stands of cotton grass and sedge shoot upwards, and above them the sunlight catches on flakes of silver and gold.
