The essence of Africa's crisis is fundamentally its extreme poverty and therefore its inability to mobilize out of its own resources even the barest of minimum resources to address any of the public health crises that Africa faces.

If you have a lot of short-term debt, it means that all of that money can be demanded in a very short period of time. Technically, short-term debt means money that's coming due within a year. Typically, it means money that's coming due within 30 to 90 days.

The time has come to end this charade. The debts are unaffordable. If they won't cancel the debts I would suggest obstruction; you do it yourselves. Africa should say: 'thank you very much but we need this money to meet the needs of children who are dying right now so we will put the debt servicing payments into urgent social investment in health, education, drinking water, control of AIDS and other needs.'

We had a booming stock market in 1929 and then went into the world's greatest depression. We have a booming stock market in 1999. Will the bubble somehow burst, and then we enter depression? Well, some things are not different.

Obama is already setting a new historic course by reorienting the economy from private consumption to public investments... Rightwing pundits bemoan the evident intention of Obama and team to 'tell us what kind of car to drive'. Yet that is exactly what they intend to do...and rightly so. Free-market ideology is an anachronism in an era of climate change.

In the early 1990s, when a lot of the developing world opened up to international capital flows... they ended up in very good long-term projects, but projects that weren't going to pay off for five or 10 or 20 years.

Everybody needs to understand that policies are going to change to make it unprofitable if you wreck the planet, those companies that continue exploring and developing fossil fuel resources for which there is no safe use are going to pay a very heavy cost for that.
