A preview of what the classroom might look like in 2025 is also a look into our planet's future.

Climate change is putting a lot of Australia's natural wonders in danger.

We currently know the Great Barrier Reef as the world's largest coral reef system at over 1,400 miles long. But as climate change continues to affect our earth's natural resources, students 20 years from now might be looking back on the reef like this:

And do you know about the Great Australian Bight? It's the home of many endangered and threatened species and includes a baby whale nursery. But new drilling developments are threatening their home.

So what'll happen to the Great Barrier Reef if nothing is done to slow the effects of climate change? According to greatbarrierreef.org, the results could be quite disastrous:

• Increasing acidity of the ocean
• Coral reefs deteriorating to a crumbling framework with very few reef building coral
• Erosion becoming a serious concern for coastal communities
• A weakened reef being further compromised by the increased frequency and severity of cyclones and storms
• Serious consequences for all organisms which depend upon it, including humans

"Fracking" may sound like a funny word, but the damage it might do is anything but.

What exactly is fracking? Besides a great substitute for that other not-so-nice f-word?

"Hydraulic fracturing, or 'fracking,' is the process of drilling and injecting fluid into the ground at a high pressure in order to fracture shale rocks to release natural gas inside." — dangersoffracking.com

So what's the danger in pumping chemicals into the ground?

Well, for one, those chemicals could end up in our water supply. What's worse is that in some communities near fracking sites, residents have found their water is filled with so many toxic chemicals, it has become flammable.

Sherry Vargson of Pennsylvania knows all too well how fracking can turn regular drinking water into something more dangerous. After an energy company began drilling not far from her home, her water became cloudy and bubbly due to increased levels of methane. And to illustrate just how dangerous these methane levels are, take a look at what happens when Sherry brings a match to her tap water.

HOLY SMOKES! Would you feel comfortable drinking or showering in this water? I highly doubt it.

Oh and one last thing: Forests could someday be a thing of the past.

Forests worldwide are being destroyed through deforestation and acid rain caused by pollution. And trees aren't just pretty to look at. They're essential for our survival and the health of our planet — they create the air we breathe, control climate stability, and aid in water purification. So once the forests are gone, we'll lose out on a lot more than just scenic views.

So while Show-and-Tell 2025 was made specifically about Australian Prime Minister Tony Abbott, there's no denying that the effects of climate change are something all of us need to think about.

The truth is, the way we're treating the planet today has an effect on what's left behind for our children and their children.

The kids in this video no doubt are adorable, but this isn't the kind of future I had in mind.
