Whenever I'm out and about, either walking or on my bike, if I see rubbish on the ground I will pick it up and bin it. Especially if that rubbish is near a water source such as a river or beach. There is already so my pollution and rubbish in our oceans. If we all took a little bit of time to do the same, it would make a big difference. We have to respect our world and keep the planet clean to future generations.
