It's better to save than to destroy 

Redeeming the Earth's original place is a must. Look what the Earth's has been through. Taking care of our nature is enough to save our environment. We already caused a lot of problems to our mother, would we want to put some more in that? It's our duty to keep our earth safe, we are living here without a doubt. Yes, you may say that you didn't ask for it, but, you don't have a choice. Hope is in our hands, so we could atleast give some manners to the Earth. There's a lot of things you could do to contribute making our world a better place. A bunch, actually. If we want to make this a better place for all of us, well we should stick to one another to get through it. 

Planting trees will decrease the possibilities of floods and gives you the oxygen you breathe in. 

Avoid using single use plastics. Like girl, go get some reusable ones. It will save you a lot.

Conserve water and electricity. It'll make a lot of difference, i guarantee that. Just turn them off when they're not in use like, it's not that hard.

Donate unwanted items. You know, there's a proverb saying "One man's trash is another man's treasure". It's better to give your unwanted items, than to throw them all away.
