Reduce, reuse, and recycle! There are 3 ways we can do away with waste. Keeping a clean Earth is good for our health! If we keep our air and land waste-free, we will be happier and healthier.

It is important to reduce what we buy. Imagine if everyone in the world bought as much as they wanted, then they did not use everything, we would have a lot of waste on Earth. We should buy less and make smart choices about what to buy. It is better to buy one big container of milk. Try not to buy single-serving cups.

Reusing items is another way to control waste. We can use many things again and share them with others. For example, we should buy reusable forks and knives instead of ones we throw away. Bring cups to the coffee shop and cloth bags to the store. If we have clothing we do not want anymore, host a yard sale or bring them to a second-hand store for someone else to buy.

Many things can be recycled. They can be remade into the same thing or new things. Recycling uses less energy and fewer resources. Aluminum cans, card board, and plastic bottles can be recycled.

What we do with our waste affects our Earth. Keep our planet clean. Reducing, reusing and recycling are important for the Earth. They are also fun and easy to do !
