Sometimes, a disabled person gives us such a major life goal which can turn the life of millions of species.
A guy with no arms and a blind guy team up to save the planet. Beating disability and saving the planet is the job which not many think of. And these guys did it all alone.
Have a look at the journey of these two friends.
Jia Wenqi has no arms, and Jia Haixia is blind but the two have been friends for a long time and what they've done over the last decade will astound you.
Their environmental exploits have brought them fame in their native China where the environment is quickly being reduced to ruins. They are the stars of a new film called; "You'll be my arms, I'll be your eyes."
Wenqi was just three years old when he touched the power line that burned off his arms. Haixia was blinded late in life when he was in an accident.
They found that they were stronger together as a team than they were on their own and soon they built a friendship so strong that they each called the other 'brother'.
One of the few ways for disabled people to earn money in China is to become involved in state environmental projects. The two learned they could plant trees to earn a living and to help secure a better future for their country.
This incredible duo has now planted over 10,000 trees in the last decade and taken care of thousands of more trees. As you can see here, it's not always easy for them.
"Let the generation after us, and everyone else, see what two handicap individuals have accomplished," Wenqi says. "Even after we're gone, they will see that a blind man and an armless man have left them a forest."
