ESS.3.1

• Survival: We drink water, breathe air, and eat plants and animals.

• Energy: We burn fossil fuels (like coal and gas) to heat our homes, drive cars, and create electricity for our computers and toys.

• Making things: We use wood from trees for paper and furniture, sand to make glass, and metals like aluminum for soda cans. 
  
  

• Running Out: If we use resources like fish faster than they can grow, we might run out.

• Pollution: Burning fossil fuels (like oil and coal) makes smoke that pollutes the air and water.

• Harming Homes: Cutting down too many trees destroys the homes of animals

Sustainability is about balance. Imagine Earth as a giant "candy jar" of resources: 

• Unsustainable: Taking candy out faster than it can be replaced until the jar is empty.

• Sustainable: Taking only enough candy so that the jar can refill itself naturally or through our help (like planting new seeds).
