Physics/Biology

Today you're going to either work on P9/10 for physics, or P6 for Biology. Physics is below thiss post, Biology is here:
You need to explain three things are that humans do to affect the environment. You will summarise these on a poster in three sections:

• Mining
• Burning fossil fuels
• Acid rain (You can also use this site to talk about landfill instead of one of the others if you prefer)

Make sure you include what they are, how they are caused and what effects they have.
