Design an invention to cut down on plastic waste in your community.

We could cut down waste by changing the way we drink.

Explanation:

If we change the way we drink by using cardboard or paperish cups we can minimize plastic cause cardboard or paper can be burned and new trees can be grown for every cardboard or paper cup used. plastic is toxic and CANNOT be burned so It builds a total over time. So this is the reason I think we should make a change.

hygrometers and hair thermometers (often found as part of hygrometers/psychrometers) can be used to measure humidity. barometers are used to measure atmospheric pressure, while anemometers are used to measure wind speed. so the 2nd and 4th choices should be the correct answers.
