Currently there are some 20,000 chemicals in use, but the scientists only have detailed information around 1,000 of them.To see the advantages of GM food you have only to consider the recent press revelation that the average lettuce receives eleven pesticide applications before it reaches the supermarket shelf.I’m sure chemicals and their role in disease will become a big issue in the 21st century as the population of the developed world worries increasingly about its health.
The reason GM food will not go away is that we need a three-fold increase in food production by the year 2050 to keep pace with the world’s predicted population growth to ten or eleven billion.It’s not just a question of more mouths to feed either.What is often forgotten is that all these extra people will take up space, reducing the overall land available for agriculture.
The world has 800 million hungry people.Until now, food supplies have been increased by improved varieties, pesticides and artificial fertilizers: the green revolution.Now we’re on the edge of a new one: a genetic revolution.
It may well be that in the long term it is the developing world that benefits most from GM food.It is true that for the next years or so GM crops may be too expensive.

Does the crab actually keep time, or does its skin simply answer to the sun's rays, changing color according to the amount of light that strikes it? To find the reason out, biologists kept crabs fo a dark room for two months.Even without daylight the crab's skin color continued to change exactly on time.
This characteristic probably developed gradually in answer to the daily rising and setting of the sun, to help protect the crab from sunlight and enemies.After millions of years it has become completely regulated inside the living body of the crab.
The biologists noticed that once each day the color of the fiddler crab is especially dark, and that each day this happens fifty minutes later than on the day before.From this they discovered that each crab follows not only the rhythm of the sun but also that of the tides.The crab's period of greatest darkening is exactly the time of low tide on the beach where it was caught!
