Three Days to See
I have often thought it would be a blessing if each human being were stricken blind and deaf for a few days at some time during his early adult life. Darkness would make him more appreciative of sight; silence would teach him the joys of sound.
Now and then I have tested my seeing friends to discover what they see. Recently, I asked a friend who had just returned from a long walk in the woods what she had observed. “Nothing in particular,” she replied.
How was it possible, I asked myself, to walk for an hour through the woods and see nothing worthy of note? I who cannot see find hundreds of things to interest me through mere touch. If I can get so much pleasure from touch, how much more beauty must be revealed by sight. And I have imagined what I should most like to see if I were given the use of my eyes, say for just three days.
On the first day, I should want to see the people whose kindness and gentleness and companionship have made my life worth living. I do not know what it is to see into the heart of a friend through that “window of the soul”, the eye. I can only “see” through my fingertips the outline of a face. I should like to see the books which have been read to me, and which have revealed to me the deepest channels of human life and the human spirit. In the afternoon I should take a long walk in the woods and intoxicate my eyes on the beauties of the world of nature. That night, I should not be able to sleep.
On my second day, I should like to see the pageant of man's progress, and I should go to the museums. I should try to probe into the soul of man through his art. The things I knew through touch I should now see. The evening of my second day I should spend at a theater or at the movies.
The following morning, I should again greet the dawn, anxious to discover new delights, new revelations of beauty. Today I shall spend in the workaday world, amid the haunts of men going about the business of life.
At midnight permanent night would close in on me again. Only when darkness had again descended upon me should I realize how much I had left unseen.
I who am blind can give one hint to those who see: Use your eyes as if tomorrow you would be stricken blind. And the same method can be applied to the other senses. Hear the music of voices, the song of a bird, the mighty strains of an orchestra, as if you would be stricken deaf tomorrow. Touch each object you want to touch as if tomorrow your tactile sense would fail. Smell the perfume of flowers, taste with relish each morsel, as if tomorrow you could never smell and taste again. But of all the senses, I am sure that sight must be the most delightful.

CHEMICAL VERSUS ORGANIC FARMING
Chemical pesticides and artificial fertilisers have been in widespread use in farming since the middle of the 20th century. When they were first introduced, many farmers welcomed them as a great way to fight crop disease and increase production. Over time, however, what some scientists have found is that their longterm use can sometimes harm both the land and people’s health.
For example, pesticides can damage the land by killing not only harmful bacteria and insects, but also helpful ones. In addition, these chemicals can stay in the soil and underground water sources for a long time. This affects the crops grown on the land and, in turn, the animals and humans who digest them. Many people worry that these chemicals may make them ill and even cause cancer. In fact, some pesticides like DDT have been prohibited in most countries because of the damage they cause to people and the environment. As for chemical fertilisers, crops grown with them usually grow too fast to be rich in nutrition. They may look beautiful on the outside, but inside there is usually more water than essential minerals, and they often have less flavour as well.
As an alternative, some farmers have switched to organic farming, and many customers have turned to organic food when they shop at the local grocery. Organic farming is simply farming without using any chemicals. Organic farmers focus on keeping their soil rich and free of disease through natural means. For example, many organic farmers use natural waste from animals as fertiliser. This makes the soil in their fields richer in minerals. It also keeps the air, soil, water, and crops free of chemicals.
Organic farmers also use many other methods to produce rich soil. They often change the kind of crop grown in each field every year. For instance, they may grow corn or wheat in a field one year, and then grow beans there the next. Why different crops are grown is that they put important minerals back into the ground, making it ready for the next batch of crops. Organic farmers also plant diverse crops that use different depths of soil to help keep it rich. For example, peanuts grow on the ground’s surface, but many other vegetables put down deep roots. The goal of using different organic farming methods is to grow good food while avoiding damage to the environment or to people’s health.
Some people would prefer to stop the use of manmade chemicals in agriculture entirely. What keeps them from doing so is the fact that chemical farming serves the high demand for food around the world. Organic farming is nowhere near able to meet that need. Therefore, there is still a long way to find a suitable solution that puts sufficient food on the dinner table while keeping people and the environment as healthy as possible.
