Every day more of the world’s forests disappear. Trees are cleared for agriculture, lost in wildfires and harvested for the valuable products they supply. Called the lungs of the planet, forests play a critical role in climate moderation. What happens when they’re gone? Are replanting and afforestation efforts helping? In If A Tree Falls: The Global Impact of Deforestation, author Nikki Tate gives an accessible and balanced look at forest practices throughout history, the growth of industry and the fight for preservation. Global deforestation affects us all. Find out what you can do to protect forests today and keep them healthy for future generations.
Wild birds are everywhere, from the dry deserts to the icy poles. We see them soaring overhead, paddling across water, flitting through trees, pecking at the ground or our backyard bird feeders and singing from fence posts. Birds contribute to the health of the planet and provide pleasure for millions of people, but wild birds are in trouble. Today, almost 200 bird species are critically endangered. They are threatened by habitat loss, invasive species, climate change, pesticides, plastics in the environment, human-made structures and other animals. Bird’s Eye View looks at why wild birds are important, why they need help and what young people all over the world are doing and can do to give wild birds a boost.
After a hang glider crashes into the pool of the house where Dinah and Madge are house-sitting, the hapless pilot creates more than a splash of suspicion in Dinah's mind. Why does this itchy intruder make off with Dinah's inflatable turtle? Why is someone trying to drive their cat-mad neighbor away? And what is the connection with the balding stranger seen lurking behind the hedge? And when Madge's boyfriend starts a campaign to save the endangered spotted owl, it seems that a crooked politician may be out to destroy the habitat of the near-extinct animal. While Madge paints, Dinah brushes aside suggestions that she be a quiet, well-behaved guest in this posh North Vancouver neighborhood. There's just too much for Dinah and her friends—tree-fanatic Pantelli and irritatingly conscientious Talbot—to investigate in this hilariously suspenseful adventure. Along with learning about endangered animals and fragile ecosystems, Dinah runs across clueless reporters and greedy developers, all the while continuing to belt out her favorite songs and satisfy her healthy appetite.
