1 Give three (03) damages to the environment, caused by tobacco.

2.1 Give three (03) damages to the environment, caused by tobacco.

• Deforestation: Land is cleared for tobacco cultivation, leading to habitat loss and reduced carbon sequestration.
• Pesticide and fertilizer use: Chemicals used in tobacco farming can contaminate soil and water, harming ecosystems.
• Cigarette butt litter: Non-biodegradable cigarette filters are a major source of plastic pollution in the environment.
• Wildfires: Discarded cigarette butts can ignite dry vegetation, causing destructive wildfires.

2.2 List two (02) pollutants related to tobacco.

• Carbon monoxide
• Nicotine
• Tar
• Heavy metals (e.g., cadmium, lead)
• Volatile organic compounds (e.g., benzene, formaldehyde)

3.1 Define the following terms: greenhouse gases; climate change.

• Greenhouse gases: These are atmospheric gases that absorb and emit radiant energy within the thermal infrared range, causing the greenhouse effect. They trap heat in the Earth's atmosphere, contributing to global warming.
• Climate change: This refers to long-term shifts in temperatures and weather patterns, primarily caused by human activities, especially the emission of greenhouse gases, leading to significant and lasting changes in global climate.

3.2 Name three (03) greenhouse gases.

• Carbon dioxide ($\text{CO}_2$)
• Methane ($\text{CH}_4$)
• Nitrous oxide ($\text{N}_2\text{O}$)
• Water vapor ($\text{H}_2\text{O}$)
• Chlorofluorocarbons (CFCs)
• Hydrofluorocarbons (HFCs)
