climate change and global warming are caused by our actions of not helping our environment. we all go out and may see some one litter but there is more to telling someone to throw away a plastic cup when it comes to helping out our environment, yes that does help and it is indeed bad to litter but there are bigger things to do. because we are on the topic of littering to help your environment you can help clean up your local beach on clean up day or just the streets around your school and home. Also if you really want to help use public transportation, this can help your environment because every car that turns of is sending gas into the atmosphere, unless you own an electric car, back to why you should use public transit over your car all the time is if every person drove there car at the least two times every day think of how much gas that would be it does add up. Though cars let out carbon dioxide and that is only 34% is transportation it really can make a difference in how much is let into the atmosphere if more people take public transit. lastly try and bring reusable bags when you go shopping so you do not have to use plastic bags every time you run in to get some milk.
you will have to fix the formatting and etc. but I tried to help you
