Saving the world from itself

It is reported that US Secretary of State John Kerry is to issue a clarion call for more 'global action' on climate change. This is all well and good but there isn't a 'global body' that can take 'global action'. There are economies competing in a 'global market'. How that translates into 'global action' against climate change I cannot see. Persuading individual countries that they are the ones that need to make a sacrifice for the sake of saving the world is very difficult. For the most part the West has already contributed its share of global emissions. Their damage is done. Now developing countries will have to be persuaded that there are better ways to economic growth and prosperity.

Palm Oil production killing the planet

Bad trade and bad products are killing our planet. We have said this before on The Thin End. There is no better example than that of palm oil. It is used ubiquitously in so many products, and its production is a major factor destroying rainforests and threatening precious species.

Demand for palm oil is 'skyrocketing worldwide'. It is used in packaging and in so much of our snack foods, cookies, crackers, chocolate products, instant noodles, cereals, and doughnuts, and the list goes on.
Bad for the planet So, why is this so bad for the planet?

The oil is extracted from the fruit of the oil palms native to Africa. It is now grown primarily in Indonesia and Malaysia, but is also expanding across Central and West Africa and Latin America.

Palm oil production is now one of the world's leading causes of rainforest destruction, and this is impacting adversely some of the world's most culturally and biologically diverse ecosystems. Irreplaceable wildlife species like t…

Time to ban organophosphate pesticides?

How would you react if your neighbour told you he was going to spray his garden with a neurotoxin used in WW2? "Oh don't worry!" he assures you, "it's only a low dose!"
"A neurotoxin?" you ask incredulously "Are you crazy?"
"It's very effective!" he asserts.
"How does it work?" you ask.
"It stops the pests' brains working" he asserts with a smile.  "Everyone uses it."
"But..."

Campaigners in the USA hope that with Scott Pruitt’s resignation, and with a new administrator Andrew Wheeler at the helm of the Environmental Protection Agency (EPA), this presents another chance to apply pressure and achieve a national ban in the United States on the organophosphate pesticide chlorpyrifos once and for all.



Organophosphate insecticides, such as diazinon, chlorpyrifos, disulfoton, azinphos-methyl, and fonofos, have been used widely in agriculture and in household applications as pesticides si…

Hummingbird exposure to pesticides

Many have responded to the campaigns to stop the use of pesticides killing bees.  Bees are not the only animals affected.

Hummingbirds are noted as a species of conservation concern by Partners in Flight, and their populations are estimated to have declined by 60% between 1970 and 2014.



New research reveals that hummingbirds and bumble bees are being exposed to neonicotinoid and other pesticides through routes that are widespread and complex. The findings are published in Environmental Toxicology & Chemistry.

To measure exposure to pesticides in these avian pollinators, investigators made novel use of cloacal fluid and fecal pellets from hummingbirds living near blueberry fields in British Columbia. They also collected bumble bees native to Canada, and their pollen, and blueberry leaves and flowers from within conventionally sprayed and organic blueberry farms.

The researchers detected pesticides and related compounds in cloacal fluid and fecal pellets of hummingbirds revealing…
