We only take from the earth, and we never give anything back. We only exploit nature. The ecology is broken, the circulation is broken; we are not living in a perfect circle, and nature is a perfect circle: if you take from one hand and you give from another, you don't destroy it.

It’s simple: A healthy ocean needs plenty of sharks. As top predators they keep fish populations strong and keep disease from spreading by removing the sick, dead or dying. Apex predators, on land as well as in the sea, make sure the strongest of species they prey on survive and thrive.

Urban gardening efforts including vertical gardens are a great way to introduce green spaces to otherwise industrial or built-up areas. They improve the air quality of cities by acting as a natural filtration system and can also reduce some of the impacts of the heat island effect.
