Answer:
Nuclear energy led to increased productivity in the production of goods for sale in global markets. There have also been moves recently towards renewable energy sources like wind and solar energy. This explains how the development of new technologies changed the world from 1900 to present. Energy technologies, including the use of petroleum and nuclear power, raised productivity and increased the production of material goods. This is a good explanation of the extent to which science and technology have brought change in the period from 1900 to the present. Why have there been shifts towards renewable energy? Concerns about climate change. The burning of fossil fuels has increased the amount of greenhouse gases in the air, which has led to the warming of the earth's surface. There is some debate about whether this is a natural or man- made phenomena. Most policy makers across the world believe it is manmade and are trying to remedy it.
Explanation:
Following decolonization, the birth rates went up in the Global South. This led to the Green Revolution where new varieties of wheat, grain and rice were introduced that were more resistant to pests and drought. Initially they were created by crossbreeding and then by genetic engineering. This explains how the development of new technologies changed the world from 1900 to present. The Green Revolution and commercial agriculture increased productivity and sustained the earth's growing population as it spread chemically and genetically modified forms of agriculture. This is a good explanation of the extent to which science and technology have brought change in the period from 1900 to the present.
