Answer:
I would suggest that we stop littering because it is dangerous for the world. Littering can cause...
⇒ Global warming
⇒ Dirty water
⇒ Acid rain
If the world does not stop littering, all the glaciers could melt, and the planet would burn much faster than normal global warming. The water would be unhealthy, and the population could die if the pollutants become lethal.
I hope this answers your question! Have a wonderful day.
