Human impact on the environment

Grade 8 · Science · Free lesson

Hi! I'm Studyfin, your tutor. Let's explore how our daily choices shape the environment around us!

Every day, humans interact with the Earth. We use resources like water, land, and air, but these activities can leave a footprint. To understand our impact, we can use active reading strategies like notetaking and annotating.

Annotating means marking up a text to highlight key ideas. For example, we can underline the causes of pollution in blue and the effects in green. This helps us see how human actions directly change ecosystems.

Coal power plants release smoke into the air. This dirty air makes it hard for trees to grow. Blue = Human Cause | Green = Nature's Effect

Once we organize our notes, we can write an informational essay to share our findings. A strong essay has multiple paragraphs, starting with an introduction, followed by body paragraphs with evidence, and a solid conclusion.

✏️ Worked example

Imagine you are writing a report on how plastic waste harms ocean life. Let's model how to take notes from a source and turn them into a clear paragraph.

  1. Read the source text carefully to find facts about plastic pollution.
  2. Annotate by underlining the main cause: 'Humans throw away millions of plastic bottles every year.'
  3. Highlight the effect on wildlife: 'Sea turtles mistake plastic bags for food and get sick.'
  4. Draft a topic sentence for your paragraph: 'Plastic pollution is a growing threat to ocean ecosystems.'
  5. Add your annotated evidence: 'When humans discard plastic, sea animals often eat it by mistake, which harms their health.'
  6. Write a concluding sentence: 'Reducing our plastic use is a simple way to protect marine life.'
