2. Distorted Body Image: The curated and filtered nature of social media can lead to body image issues. Exposure to images of unrealistic beauty standards has been linked to low self-esteem and body dissatisfaction, especially among young people.
3. Disrupted Sleep Patterns: The blue light emitted from our screens can disrupt our natural sleep cycles, leading to sleep deprivation and fatigue. This can have a negative impact on our overall mental well-being.
4. Addiction and Isolation: The addictive nature of social media can lead to excessive screen time and a constant need for validation through likes and comments. This can result in feelings of isolation and disconnection from real-life relationships.
Examples and Facts:
- A study by the Royal Society for Public Health found that Instagram is the worst social media platform for mental health, with higher rates of anxiety, depression, loneliness, and body image concerns among its users.
- Research published in the Journal of Adolescent Health showed a link between heavy social media use and poor sleep quality, as well as high levels of anxiety and depression in teenagers.
- The American Academy of Pediatrics recommends that parents limit the use of screens and encourage healthy screen-free activities for children to promote mental well-being.
Conclusion:
In conclusion, while social media has its benefits in terms of connecting people and sharing information, it is important to recognize its potential impact on mental health. By being mindful of our social media usage and setting boundaries, we can take steps to protect our mental well-being in the digital age. Thank you.

Oral Presentation: What Are the Environmental Impacts of Plastic Pollution?
Introduction:
Plastic pollution has become a global environmental crisis with far-reaching consequences for ecosystems, wildlife, and human health. The research question I aim to explore is: What are the environmental impacts of plastic pollution?
Claims and Findings:
1. Marine Life Endangerment: One of the most visible impacts of plastic pollution is the harm it causes to marine life. Animals such as seabirds, turtles, and fish often mistake plastic debris for food, leading to ingestion and entanglement. This can result in injury, suffocation, and even death.
2. Water Pollution: Plastic waste can contaminate water sources such as rivers, lakes, and oceans, affecting aquatic ecosystems and the organisms that rely on them. The leaching of harmful chemicals from plastics can disrupt ecosystems and harm wildlife.
3. Microplastics in the Food Chain: Over time, plastic debris breaks down into smaller pieces known as microplastics. These particles can be ingested by marine organisms and eventually make their way up the food chain, potentially exposing humans to harmful chemicals through seafood consumption.
4. Carbon Emissions and Climate Change: The production, transportation, and incineration of plastics contribute to greenhouse gas emissions, exacerbating climate change. Plastic pollution also hinders the natural carbon sequestration processes of ecosystems, further impacting the environment.
Examples and Facts:
- The Great Pacific Garbage Patch, a massive accumulation of plastic debris in the Pacific Ocean, is estimated to be larger than the size of Texas and continues to grow.
- A study published in the journal Science found that over 90% of seabirds have ingested plastic, with this number projected to reach 99% by 2050 if current trends continue.
- Plastic pollution is estimated to cause over $13 billion in economic damage to marine ecosystems each year, impacting industries such as tourism, fishing, and coastal development.
Conclusion:
In conclusion, the environmental impacts of plastic pollution are significant and widespread, posing a threat to ecosystems, wildlife, and human health. It is crucial for individuals, businesses, and governments to take action to reduce plastic waste, promote recycling and responsible consumption, and support policies that address this urgent environmental issue. Together, we can work towards a more sustainable and plastic-free future. Thank you.

Oral Presentation: What are the Impacts of Climate Change on Global Agriculture?
Introduction:
Climate change is a pressing issue that is significantly impacting global agriculture. The research question I aim to explore is: What are the impacts of climate change on global agriculture?
Claims and Findings:
1. Changes in Temperature and Precipitation Patterns: Climate change is leading to more frequent and intense weather events, such as heatwaves, droughts, floods, and storms. These unpredictable weather patterns can disrupt growing seasons, reduce crop yields, and threaten food security.
2. Shifts in Pest and Disease Dynamics: Rising temperatures and changing climate conditions are altering the distribution and behavior of pests and diseases that affect crops. This can result in increased pest pressures, crop damage, and the need for more intensive pesticide use, impacting both farmers and the environment.
3. Water Scarcity and Irrigation Challenges: Climate change is affecting water availability and quality, leading to water scarcity in many regions. Changes in precipitation patterns and melting glaciers are impacting irrigation systems, reducing access to water for crop production and exacerbating water stress for farmers.
4. Loss of Biodiversity and Ecosystem Services: Climate change is causing shifts in ecosystems and habitats, leading to loss of biodiversity and ecosystem services that are essential for agriculture, such as pollination, soil fertility, and natural pest control. This loss can have cascading effects on the productivity and resilience of agricultural systems.
Examples and Facts:
- According to the Intergovernmental Panel on Climate Change (IPCC), global food security is at risk due to climate change, with projected declines in crop yields for major staple crops such as wheat, rice, and maize in the coming decades.
- A study published in Nature Climate Change found that extreme heat events caused by climate change could reduce maize and wheat production in the United States and other key agricultural regions by up to 20% by 2050.
- The Food and Agriculture Organization (FAO) estimates that around 80% of the world's agriculture is rainfed, making it highly vulnerable to climate variability and extreme weather events.
Conclusion:
In conclusion, the impacts of climate change on global agriculture are profound and multifaceted, affecting crop production, food security, and the livelihoods of farmers worldwide. It is crucial for policymakers, researchers, and stakeholders to prioritize climate adaptation and mitigation strategies, invest in sustainable agricultural practices, and support resilient farming communities to address the challenges posed by climate change. Together, we can work towards a more sustainable and secure food system in the face of a changing climate. Thank you.

Oral Presentation: How Does Climate Change Impact Our Food?
Introduction:
Hey everyone, have you ever wondered how climate change is affecting the food we eat? Today, I want to explore the question: What are the impacts of climate change on global agriculture?
Impacts of Climate Change on Agriculture:
1. Changing Weather Patterns: Climate change is bringing more extreme weather events like heatwaves, droughts, and floods. These sudden changes can mess up the timing of when crops should be planted and harvested, which can lead to lower crop yields and food shortages.
2. Pesky Pests and Diseases: With warmer temperatures, pests and diseases that attack crops are spreading to new areas. Farmers have to deal with more bugs munching on their crops, which means they may have to use more pesticides that can harm the environment.
3. Water Woes: Climate change is messing with water supplies, making it harder for farmers to water their crops. Many regions are facing water shortages, which can lead to crop failures and struggling farmers.
4. Biodiversity Loss: As the climate changes, habitats and ecosystems are also changing. This can lead to a loss of the plants and animals that help farmers grow their crops. Without them, it's harder to produce food sustainably.
Examples and Facts:
- The Intergovernmental Panel on Climate Change warns that climate change could reduce crop yields for important foods like wheat, rice, and maize, putting our food security at risk.
- A recent study found that extreme heat events caused by climate change could reduce the production of staple crops like maize and wheat by up to 20% in the United States by 2050.
- The Food and Agriculture Organization estimates that 80% of agriculture worldwide relies on rain, making it vulnerable to changes in the climate.
Conclusion:
In closing, climate change is not just a far-off issue—it's impacting the food on our plates right now. It's more important than ever for us to take action to support farmers, promote sustainable agriculture, and find ways to adapt to a changing climate. By working together, we can ensure that everyone has enough food to eat, even as the world changes around us. Thank you.
