"With the price of gasoline and with the problems with clean air, it's important we get electric vehicles out on the road."
On California roads there are about two thousand electric cars. By 2003, ten percent of all new cars may be required to have zero emissions. This is a mandate automakers say it is way ahead of its time.
Gloria Bergquist of the Alliance of Auto Manufacturers says, "The technology (for zero emissions) isn't here yet; it still needs advancement in driving range to make it more appealing to a wider consumer audience".
Automakers blame it on the batteries. Power runs out on most cars after about 70 miles. However, some cars can now go more than 100 miles on a charge. Batteries are expensive. Carmakers say there is nothing they can do about it.
Tim Carmichael of the Clean Air Coalition says, "The automakers have not built a vehicle unless required to do so, so it's very important for the state to stay committed to this program requiring automakers to build small amounts in beginning years and then the market will take off".

"Hold on, lad, 1 am going to buy only one pair? "I know that," said he, "but I want you to see how beautiful these are. Aren't they wonderful!' There was on his face an expression of seriousness and pride and delight as if he were showing to me the secret of his religion(宗教). I became far more interested in him than in the socks. I looked at him in surprise. "My friend," said I, "if you can keep this up, if this is not just from a new job, if you can keep up this high spirit and excitement day after day, in ten years you will win every sock shop in the United States."

All this only goes to show just how important it is to set up a plan to conserve and divide up fairly natural resources on a worldwide scale.
This is a matter of life and death because world population is expanding at an incredible rate. By the middle of the next century population will expand every year by as much as it did in the first 1,500 years after Christ. In the southern, poor parts of the globe, the figures are enough to make your hair stand on end. Even supposing that steps are taken to stabilize world population in the next fifty years, the number of inhabitants per square kilometer will increase by from 4 in the United States to 140 in South East Asia. What can we do about it?
In the first hypothesis we do nothing. By the year 2000, the southern parts of the world would then have a population greater than the total world population today.
Alternately we could start acting right now to bring birth rate under control within fifteen years so that population levels off. Even then the population in the southern areas would not stop growing for seventy-five years. And the population would level off at something like twice today's figure.
Finally, we could wait ten to twenty years before taking action. If we wait ten years the population of the southern area would stabilize at 3,000 million. Even today the number of potential workers increases by 350,000 people per week. By the end of the century this figure will reach 750,000; in other words, it will be necessary to find work for 40 million people per year--not to speak of food.
What this means in practical terms we can scarcely imagine. But clearly if we do nothing, nature will solve the problem for us. But at what cost!
