To increase the depth of my speech, I will incorporate recent statistics and expert opinions related to my topic. For instance, if my speech is about the impact of climate change on global food security, I will research current data from reputable sources such as the Food and Agriculture Organization (FAO) or the Intergovernmental Panel on Climate Change (IPCC).
I plan to include specific information about how climate change is projected to affect crop yields over the next decade. For example, I might find a report indicating that certain staple crops, such as wheat and maize, could see yield reductions of up to 30% in some regions by 2050 due to increased temperatures and changing precipitation patterns.
I will present this information during the body of the speech, specifically in the second major point, which discusses the projected impacts of climate change on agriculture. After outlining the general effects of climate change, I will introduce these statistics to provide concrete evidence of the potential crisis facing global food security. This addition will not only enhance the credibility of my argument but also help to paint a more vivid picture of the challenges we are likely to face.
