Human beings and animals live
in one world. We know a lot about this world, it is true., but we do not know everything. We look for new and interesting animals because we can learn from them.
We are finding them, but at the same time we are losing many more. We change thing.s in our world quickly, but animals change
very slowly. They are all going to disappear soon - or we can help them. Our home is their home too; we cannot forget this .
