This week we learned about pollution. I never knew that garbage was so interesting!
On Tuesday, it was World Environment Day. Danny, Brian and I cleaned up the schoolyard. All of our classmates helped. We took bags and picked up the garbage. It was great to see everyone working together!

Later that day, Brian, Danny and I went for a walk around our neighbourhood. When we saw garbage, we picked it up. Danny found a used toy car with one broken wheel. He took it home, cleaned it and fixed it.

On Wednesday, we sorted our school’s garbage. We put on gloves and divided the garbage into different piles: glass, metal, plastic, paper and everything else. Most of the garbage was paper. People wasted a lot of paper! There was less plastic than paper and more plastic than metal. There was the least amount of glass.
Today, Danny made a car out of garbage! He used a big box for the body and pieces of wood for the seats. He used a bit of glue to put the wheels on. The wheels were plastic lids. It was great!
We throw garbage away. But where does it go Later this month, we will go on a class trip to the city recycling centre. Thousands of tons of garbage are sent there. We will see the workers sort all of our garbage for recycling.

I think it’s our duty to protect the environment. I am only one person, but if I do my part, the earth will be a cleaner and safer place. If each of us does something for the environment, all of us will have a better life.

“Hazardous” means dangerous. Some hazar dous waste is poison—it makes people sick. Some products explode or burn very easily. Hazardous things usually have these labels: “poison”, “caution”, “warning” or “danger”. What can we do about hazardous waste Buy less of it!
Let’s Do It!
And when you take out the garbage, don’t take out your hazardous waste. Hazardous waste in your garbage is bad for the environment. Why Because we usually bury or burn our garbage. This can make people and the environment sick.
Many countries have laws about hazardous waste. The laws don’t allow people to bury or burn hazardous waste with other garbage. Many cities in North America keep their hazardous waste in special places. Some have ways to burn it at very high temperatures: from 900 to 1 100 degrees centigrade. Hazardous waste is buried two kilometres under the ground in some places. That’s deep!
