Challenge 4: What do you do at school or at home to help protect the environment?

At home, we turn off our lights when we don't need them so we can save electricity. We also use the reusable shopping bags. This saves a lot of plastic from being wasted over time. Another thing our school finds very important, which it is, is recycling anything that can be recycled so we can reuse this stuff in the future.
