Understanding Key Environmental Terms

  • The environment: This refers to the natural world around us, including the land, air, and water, and all the plants and animals.

  • Pollution: This is the presence of harmful substances or things in the environment. It can be air pollution (from cars or factories), water pollution (from waste), or even noise pollution.

  • Climate change: This describes long-term shifts in temperatures and weather patterns globally. It is mainly caused by human activities.

  • Wildlife: This term refers to animals, birds, and plants living in their natural habitat.

  • Endangered: When an animal or plant species is endangered, it means there are very few of them left, and they are at risk of disappearing forever.

Actions to Help Our Planet

  • Protect: To protect something means to keep it safe from harm or danger. For example, we protect forests.

  • Save: This word is similar to protect, often meaning to rescue something from danger or to prevent it from being lost. We can save endangered animals.

  • Prevent: To prevent something means to stop it from happening. We try to prevent pollution.

  • Recycle: This means to process used materials (like paper, plastic, or glass) so they can be used again. It helps reduce waste.
