Science is cool! But it's easy for that to get lost in textbooks sometimes.

The fundamental essence of science, which I think we've lost in our education system, is poking something with a stick and seeing what happens. Embrace that process of inquiry.

The goal of each EarthEcho Expedition is to inspire and empower youth around the world with the knowledge and tools to take an active role in protecting critical natural resources in their own communities.

My father's plan was, we were going to grow up and travel the world.

I hate plastic bottles. Just think about it before you buy one. We pay more for a gallon of water than we do for a gallon of gas. I think people will realize that water quality standards in most municipalities are as good or better for the stuff coming out of the tap than bottled water companies. You'll save money and save the environment, too.

In many ways, our homes act as one big drain that, through our daily relationship with water, carries many toxic substances into our waterways and the environment.

The earliest memories I have of the ocean are actually stories - stories from my grandfather, the legendary ocean explorer and conservationist Jacques Cousteau. My passion for ocean conservation stems from learning at a very young age that we're all connected; we're all in this together.

My grandfather was Jacques Cousteau, a pioneer of ocean exploration and the co-inventor of scuba diving. Back in the 1940s when he tested out his invention which allowed humans to swim freely in the ocean with a portable air source for the first time in history, very little of the ocean had been explored let alone captured on film.

One of my big pet peeves is single-use plastic bags. I think it's one of the stupidest ideas in the world.

Fossil fuels and mining is a short-term gambit. If we develop those resources at the expense of the environmental gold mine that is the Great Barrier Reef, we will all lose in the long run.

EarthEcho Expeditions represents the culmination of more than a decade of working with educators and youth from around the world. EarthEcho Expeditions uses the thrill of adventure to inspire and empower a new generation of environmental champions.

I have spent many years working in education and media, from hosting documentaries to being a spokesperson for Discovery Education to revolutionizing youth environmental service through my non-profit, EarthEcho International.

With EarthEcho Expedition: Acid Apocalypse, we are working with youth leaders and noted experts on the changing chemistry of our ocean to help illuminate one of our most pressing and inscrutable environmental issues.

I travel all over the country speaking to young people, and I am always amazed at how engaged in environmental conservation they are.

Helping people understand the impact of key environmental and human issues worldwide is something that I'm passionate about. CNN's 'Going Green' series of specials are engaging viewers around the world through important messages of conservation and hope.

Truly, we do live on a 'water planet.' For us, water is that critical issue that we need. It's the most precious substance on the planet, and it links us to pretty much every environmental issue, including climate change, that we're facing.

They say that our sense of smell is one of the strongest triggers of memories. Of course, our sense of smell is integral to our sense of taste, so it is no surprise, then, that in a life full of moving and traveling, food has always been a source of familiar comfort for me.
