Observing and Helping in Nature

Ondřej and Hanka are friends. All year round, every week, they've been going into nature and discovering incredible things there. They wrote about what they saw in a diary. In the end, it became a book – NATURE OBSERVATIONS. But Ondřej and Hanka decided to continue. THEY WON'T JUST OBSERVE – THEY WILL HELP NATURE TOO! Don't you want to give it a try as well?
