India’s disappearing slums

Not because they are improving them, however but because the authorities want the land for other things such as building roads or new hotels before the 2010 Commonwealth Games. Is this the answer? Some are provided with new homes but the majority don’t get any help at all. The authorities say they are there illegally and should go.

Global warming – yes or no?

Global dimming
http://en.wikipedia.org/wiki/Global_dimming
Fossil fuel use, as well as producing greenhouse gases, creates other by-products. These by-products are also pollutants, such as sulphur dioxide, soot, and ash. These pollutants however, also change the properties of clouds.
Clouds are formed when water droplets are seeded by air-borne particles, such as pollen. Polluted air results in clouds with larger number of droplets than unpolluted clouds. This then makes those clouds more reflective. More of the sun’s heat and energy is therefore reflected back into space.
This reduction of heat reaching the earth is known as Global Dimming.
Impacts of global dimming: millions already killed by it?
Global warming results from the greenhouse effect caused by, amongst other things, excessive amounts of greenhouse gases in the earth’s atmosphere from fossil fuel burning. It would seem then, that the other by-products which cause global dimming may be an ironic savior.
A deeper look at this, however, shows that unfortunately this is not the case.
Health and environmental effects
The pollutants that lead to global dimming also lead to various human and environmental problems, such as smog, respiratory problems, and acid rain.
The impacts of global dimming itself, however, can be devastating.
Global dimming can be dealt with by cleaning up emissions.
However, if global dimming problems are only addressed, then the effects of global warming will increase even more.

Fairtrade water project in Argentina. Water from wine!!!

A lot of subtitles here but this is a good video to watch. It is short folks! Don’t think I am encouraging you to go and drink wine. NO. Adults only please. This does show the power of cooparative work and fair-trade.

Rainforest to save lovers of chewing gum?

A bonus of the new gum for Britain's local authorities is that it will be biodegradable and start to break down almost immediately after use, potentially saving councils millions in pavement cleaning bills. The chicozapote tree is about to tapped for its resin. It doesn’t do as much damage as deforestation for farming or building and may provide jobs for some people. You can read more here and see a slide show with commentary here.
