Mangroves have many friends. These people understand the importance of mangroves. Every person who likes fishing should be a friend of mangroves because most of the fish they want to catch spent part of their life in mangroves.
Mangroves in Australia are nearly always on public land. Government authorities should be protecting them. But there are many people who think that mangroves are smelly and yucky and have not learnt to respect these important ecosystems.
