Over the past 20 years scientists have been using technology on nature to improve food supplies. They are producing genetically modified (GM) foods by modifying or changing , the genes of plants and animals. Genes are the codes in the cells of every living thing that determine the way they look and grow. In humans, genes determine characteristics such as the color of our eyes and how tall we are. By changing the genes of plants, scientists can cause crops to produce more become resistant to pests and disease and have more nutritional value. Genetically modified plants can have great benefits by increasing food supplies protecting the enviroment and even improving nutrition
how will we feed the growing population? the world's population is expected to exceed 8 billion by 2025.Much of this increase will occur in the cities of developing countries. Unfortunately, food production, instead of increasing, has decreased over the last ten years.As it is,some 40000 people die form hunger-related causes every day. the only way to increase food production seems to be through technology,since land and water are getting scarce.In Africa, millions of people don't have enough food to eat and are dying because drought has destroyed their food supply.If GM food crops could be developed that could resist droughts or grow in poor, dry, or salty soils , this would help poorer countries.
