...Like Canaries in a Coal Mine I was shocked to learn from "Bye Bye Birdies" [May 29] that climate change may be killing migratory birds. I had no idea there was a link between declining bird populations and global warming. We should not forget that the death of even a single bird because of environmental factors can be linked to the fate of human beings, since we all depend on the health of our ecosystem.

...That same desire to market to, and invest in, some of the world's poorest countries is behind Tata's affinity for Bangladesh and Africa. Tata group recently finalized a $3 billion power, steel and coal deal in Bangladesh, the biggest investment in that country's history. In South Africa, the group has investments in mining, tourism and engine manufacturing. There is an instant-coffee plant in Uganda, a bus factory in Senegal and a phosphate plant in Morocco. "We look at countries where we can play a role in development," says Tata. "Our hope in each is to create...
...helped by playing a massive role in environmental pollution and doing little to help residents of the delta. The international community, especially the U.S. and Britain, should do more so the world does not wake up to another Iraqi-style insurgency.

...Waste disposal. Nuclear plants produce radioactive waste, which must be carefully shielded and stored. According to Melbourne University's Sevior, "the amount of waste that comes out of a typical [nuclear] plant is around 30 tonnes a year. The amount of waste that comes out of a coal-fired power plant is around 1,000 tonnes a day." Used fuel rods can be reprocessed into new fuel, reducing the volume of waste that needs to be stored by over 90%; turning the waste into synthetic rock reduces this even further. If it's not reprocessed, this high-level waste stays...
...sides differ on how to compare the costs of nuclear and other power. Nuclear plants are hugely expensive to build: an average-sized plant costs about $A2.5 billion. But they need very little fuel-uranium yields up to 1 million times as much energy as the same quantity of coal. The ansto study found that, taking waste management costs into account, nuclear power from an advanced plant "is cheaper than generating it from coal or a [clean coal] station...
