Waterways are clearer, the food chain is less contaminated with plastic – and there are fewer “flying toilets”.

A year after Kenya announced the world’s toughest ban on plastic bags, and eight months after it was introduced, the authorities are claiming victory – so much so that other east African nations Uganda, Tanzania, Burundi and South Sudan are considering following suit. But it is equally clear that there have been significant knock-on effects on businesses, consumers and even jobs as a result of removing a once-ubiquitous feature of Kenyan life. “Our streets are generally cleaner which has brought with it a general ‘feel-good’ factor,” said David Ong’are, the enforcement director of the National Environment Management Authority. “You no longer see carrier bags flying around when its windy.

Mikä ilmastonmuutos?

Se vaikuttaa ihmistoimintaan ja luonnonympäristöihin jo nyt ja vaikutukset tulevat lisääntymään tulevaisuudessa. Ihmisten toiminnan vaikutus ilmastonmuutoksen etenemisessä on ratkaiseva ja katastrofaalinen ilmastonmuutos voidaan edelleen estää, jos niin halutaan. Ilmastonmuutos on osa moninaista ympäristö- ja kestävyysongelmien vyyhtiä ja toisaalta sen ratkaisut edustavat kestävän kehityksen mukaista elämäntapaa. Jotta erilaisia kestävyyshaasteita voitaisiin pätevällä tavalla ratkaista, on tunnettava juuri kyseisen ongelman syyt ja parhaat ratkaisumallit. Ilmastonmuutos on moniin muihin kestävyyshaasteisiin verrattuna valtavan suuri ja jo itsessään hyvin kompleksinen ilmiö. The Value Web. Hurricane Irma - the path of destruction.

Top dog: Scientists teach border collie to understand sentences and 1,000 words

But Chaser has proved herself as the undoubted top dog after learning to understand 1,000 words - plus a smattering of English grammar. Researchers believe the nine-year-old has learned to respond to words in the same way that a human child does. They say Chaser was able to demonstrate understanding of nouns and verbs. In the first three years, she learned and remembered 1,022 proper nouns. She could also respond to novel objects. City Birds Outsmart Country Birds. City dwellers can attest that the animals they share the city with—the pigeons, rats, roaches—can all be pretty brazen when they're prowling for a bite.

City Birds Outsmart Country Birds

This is Scientific American’s 60-Second Science, I’m Christopher Intagliata. Got a minute? While visiting Barbados, McGill University neurobiologist Jean-Nicolas Audet noticed that local bullfinches were accomplished thieves as well. [Jean-Nicolas Audet:] “They were always trying to steal our food. And we can see those birds also entering in supermarkets, trying to steal food there.” And that gave him an idea. [Audet:] Since this bird species [is] able to solve amazing problems in cities, and they're also present in rural areas, we were wondering...

Yet the government–particularly the federal government–seemed unprepared for the disaster.

Officials, even including President George W.

(For one thing, many had nowhere to go. Katrina pummeled huge parts of Louisiana, Mississippi and Alabama, but the desperation was most concentrated in New Orleans.
