Jenny's blog
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.
