Things could be looking up for one of the planet's most endangered species, the black rhino.
For the first time in 25 years, black rhinos that have grown up being cared for by people are being let out to live in the wild on their own.
There used to be loads of black rhinos living in Africa, but thousands of them were killed in the 1980s.
Now a project has been so successful that the people behind it are happy to release some of them into the wild.
The team has been working in Kenya, which is one of the countries where rhinos have struggled the most.
In the 1970s as many as 20,000 black rhinos were living in Kenya, but now only 500 are left.
Many of them were killed by poachers while others struggled because the places they liked to live in were destroyed.
