Mini Lesson
Humans are part of nature, but our actions can either help or harm the natural world. Some of our choices protect ecosystems and wildlife, while others damage the environment through pollution, deforestation, and waste.
Positive Human Impacts
- Planting trees helps restore forests and reduces carbon dioxide in the air.
- The 3 Rs help nature: reduce (use less), reuse (use things again), and recycle (turn used items into new things), so less trash goes to a landfill.
- Creating nature reserves gives wildlife a safe space to live and breed.
- Using solar and wind energy reduces pollution from burning fossil fuels.
- Cleaning up beaches and rivers protects ocean and river habitats.
Negative Human Impacts
- Cutting down forests destroys habitats and releases stored carbon.
- Dumping waste in rivers poisons fish and other water life.
- Burning fossil fuels releases gases that cause climate change.
- Oil spills at sea coat sea animals and kill ecosystems.
- Overfishing reduces fish populations and upsets food chains.
Words to know
Pollution
Harmful waste that dirties the air, water, or land
e.g. Smoke from cars adds to air pollution.
Recycling
Turning used items into new things instead of throwing them away
e.g. Recycling paper saves trees.
Deforestation
Cutting down large areas of forest
e.g. Deforestation destroys animal habitats.
Conservation
Protecting nature and using its resources wisely
e.g. Nature reserves help with conservation.
Ecosystem
A community of living things and the place where they live
e.g. A pond is a small ecosystem.
Every choice matters — even small actions like recycling or picking up litter can make a positive difference to nature.
