“Tactic No. 3: Avoid Slowly Crawling Up to Speed Conventional wisdom says that jackrabbit starts consume more fuel. But it turns out that nursing your speed up to the limit too slowly also lowers mpg. How can that be? Cars get poorer fuel economy in lower gears, and accelerating too slowly prevents upshifting at an efficient rate. The best acceleration rate varies with the vehicle, gear ratios and weight. But in our testing we found that taking 15 seconds to accelerate to 50 mph used less fuel than taking 30 seconds to reach the same speed, because the car entered its top, fuel-saving gear sooner.”

Can the world feed 10 billion people?
Already, one-third of children in Niger are malnourished, and global warming will further undermine agricultural output in the desertifying Sahel. Even if the current birth rate is halved by 2050, the population will still explode — from 14 million today to 53 million by 2050. If the birth rate continues at current levels, the population could reach a totally unsustainable 80 million. Unless there is an immediate commitment to family planning, the scale of human suffering over the next three decades in the Sahel could equal or exceed that caused by HIV/AIDS in the past 30 years.
