Positives of genetic engineeringGenetic engineering is the practice of manipulating the genes of an organism It is used to produce crops that are more resistant to insects and diseases Some genetically modified crops grow more quickly Some drugs and vaccines are produced by genetic engineering It may become possible to change human’s genetic characteristics. Scientists may use genetic engineering to cure diseases. Inherited illnesses would no longer exist Genes could be changed before a baby is born It could also be possible to clone human organs We could all have replacement body part Humans could live longer, healthier lives
Negatives of genetic engineering There are ethical concerns about human genetic engineering Parents might want to choose their children’s characteristics This would be unnatural It would be unacceptable in most religions Soldiers could be cloned from the genes of the strongest people Clones might be used like robots to do certain jobs Clones might even be developed just for organ replacements Society and human evolution would change completely Currently, human genetic engineering is prohibited
Genetically-Modified (GM) foods: Advantages Farmers can produce crops that grow bigger and faster Some GM crops are more resistant to disease or insects This could be important for food production in developing countries Faster growing cereals, fruit and vegetables will mean more profit GM foods can be modified to look perfect They may be more attractive to customers
Genetically-Modified (GM) Foods: Disadvantages There may be risks involved in the genetic engineering of foods. GM crops might change whole ecosystems Food chains could be broken if crops are resistant to predators Organic foods are produced without chemicals or genetic modification Organic farming may be slower and more expensive However, the environment is not damaged by fertilizers or pesticides.
Global issues Problems in developing countries Developing countries face a range if problems Standards of healthcare and education are low Life expectancy is usually lower than in developed countries There is a lack of infrastructure, employment and good quality housing Many people are forced to live in poverty Food, drinking water and basic medicines are in short supply
How to help developing countries The best form of help for developing countries is development aid Richer nations can help by investing in long-term projects Governments and charities can help by building new houses and schools Globalization may also help developing countries Multi-national companies can creating jobs in developing countries On the other hand, many people emigrate to find work in richer countries They often sand money back home to their families This money helps to improve the standard of living in developing countries
Immigration Some people move to another countries in search of a better life Many immigrants come from less developed countries Richer, industrialized countries may offer opportunities for employment Free healthcare and schooling are available in some developed countries Other people migrate to a foreign country to improve their academic qualifications
