Cause and Effect Thesis Statement Examples
Climate Change
Thesis: Climate change endangers life on earth because it is leading to an increase in catastrophic weather events, warmer average temperatures, and a rise in sea levels that threaten coastal communities.
- Cause: Greenhouse gas emissions from industrial activities, deforestation, and fossil fuel use.
- Effect: Increased natural disasters such as hurricanes, floods, and heatwaves; rising temperatures and melting ice caps; displacement of coastal populations due to flooding.
Obesity
Thesis: The increase in obesity in our country is due to food commercials, cheap fast food, and video games.
- Cause: Aggressive marketing by food companies, availability of unhealthy and affordable fast food, and sedentary lifestyles promoted by video games.
- Effect: Higher obesity rates, leading to health problems such as diabetes, heart disease, and low self-esteem.
Global Warming
Thesis: The Great Barrier Reef is threatened by global warming; the rising water temperature causes reef bleaching, making the reef less colorful and more prone to disease.
- Cause: Rising global temperatures due to increased carbon emissions.
- Effect: Coral bleaching, loss of biodiversity in the reef ecosystem, and disruption to marine life that depends on coral reefs for survival.
Childhood Obesity
Thesis: The growing childhood obesity epidemic is a result of technology.
- Cause: Excessive screen time, increased use of mobile devices, and less physical activity among children.
- Effect: Higher obesity rates, leading to long-term health problems like type 2 diabetes, heart disease, and mental health issues.
Video Game Addiction
Thesis: The effects of video game addiction have the potential to be severe, including disruption to careers, decline in overall health, and sleep deprivation.
- Cause: Excessive gaming, often combined with poor time management and lack of self-regulation.
- Effect: Negative impact on social relationships, academic performance, physical health (e.g., eye strain, poor posture), and mental health (e.g., anxiety, depression).
