Human Impact on Earth's Systems

How People Change the Planet

Humans affect Earth's systems in many ways. Activities like deforestation, pollution, and burning fossil fuels change the land, air, and water.

Major Human Impacts

  • Climate Change: Burning fossil fuels releases greenhouse gases, warming the planet.
  • Pollution: Trash, chemicals, and plastics harm ecosystems.
  • Resource Use: Mining and farming change landscapes and water use.

Solutions and Actions

Scientists and communities work to reduce these impacts by recycling, conserving energy, and protecting nature.

Examples

  • Reducing air pollution by using cleaner energy sources.

  • Restoring forests to help absorb carbon dioxide.

In a Nutshell

Humans change Earth's systems, but we can take action to protect our planet.
