The 'Great Big Story' about endangered animals might be a comprehensive account of various endangered species. It could cover their current situation, the reasons for being endangered like habitat loss, poaching, and climate change. It may also include efforts being made to protect them.
There are likely to be the African elephants in the 'Great Big Story'. They are endangered because of illegal ivory trade. The vaquita, a small porpoise in the Gulf of California, is also highly endangered due to bycatch in fishing nets. These are just a few of the many endangered animals that might be part of this 'Great Big Story' which is probably trying to show the importance of protecting these amazing creatures.
An 'endangered novel' could refer to a novel that is at risk of being forgotten or lost. Some novels are considered 'endangered' because they might be from a niche genre that doesn't get much mainstream attention. Also, if the publisher goes out of business and there are few copies in circulation, it can become endangered.
One possible story could be about a magical pumpkin patch where the pumpkins are losing their magic because of some outside threat, and a brave hero has to find a way to restore it and protect the pumpkins from endangerment.
Maybe a story about a group of kids trying to save a pumpkin patch from being destroyed by developers. They come up with creative ways to raise awareness and protect the pumpkins.
The description has potential. In a book about animal behaviors, the 'spare life' might be highlighting the fact that animals often have to make do with limited resources and face various challenges. A novel exploring these aspects of animal behavior, such as how they adapt to changing habitats or deal with competition for food, could be fittingly described this way.
