Birds are my favourite animals type. Without the birds, Insect population will grow rapidly. Insects will evolve their food habits as their source of food will be diminishing rapidly. The population that prey on birds (especially chickens which living beings prey on including humans but not just us) now have to adapt to new food types, if they can.

Habitats like forests, marshes and grasslands affect people across the whole planet, even those living hundreds of miles away – they store carbon, keep the climate stable, oxygenate the air and transform pollutants into nutrients. But without birds, many of these ecosystems may not exist.

What will happen if ALL types of birds are replaced by legendary creatures called dragons?!
Just imagine if dragons replaced birds. I mean small annoying dragons flying around towns and beaches stealing your food, big exotic dragons living in remote places, friendly dragons, fierce dragons, FLIGHTLESS DRAGONS, dragons in zoos dragons in the wild, JUST DRAGONS!!!
