You've heard about the impact that our technology-driven population is having on the planet -- from cars, to energy factories, to the over-consumption of the earth's resources.
It's causing a lot of problems.
Yet, inventors are also using this technology to improve lives across the planet. Here are a few of their creations (or soon-to-be ones):
1. A high-tech sieve that makes the ocean drinkable
Yes, you can already turn the ocean into drinkable water through existing, industrial-scale desalination plants.
But these plants are often costly and can damage the environment: They use large amounts of energy, produce greenhouse gases and can harm marine life.
So, researchers in the UK have developed a sieve made out of graphene that may be able to filter out salt using less energy.
That could help provide safe, clean, drinkable water -- which is a rare resource in many countries.
In fact, the United Nations predicts that in less than a decade, 14% of people around the world will not have access to sufficient water resources where they live.
