We do not inherit the earth from our ancestors, we borrow it from our children. (Native American Proverb)

Have a look at how people celebrate Earth Day and why we need to celebrate International Mother Earth Day. The wealth of the nation is its air, water, soil, forests, minerals, rivers, lakes, oceans, scenic beauty, wildlife habitats and biodiversity... that's all there is. That's the whole economy. That's where all the economic activity and jobs come from. These biological systems are the sustaining wealth of the world. (Gaylord Nelson)
