Forests cover around 30 % of the Earth’s surface, are home to millions of species, capture and store carbon dioxide (CO2), influence the local climate and provide us with water. This month, Horizon examines how the health of the world’s forests impacts on climate change. We explore the link between deforestation, forest degradation and CO2 emissions, examine the push to combine farming and forestry for better land management, and find out how scientists are using tree rings and DNA to combat illegal logging.
Did you know there are 200 million insects for each human on the planet? This October, Horizon delves into the mysteries of this diverse set of creatures and their seemingly infinite survival skills. We talk to researchers about why it's vital to maintain the diverse range of insect species, find out how robots and ants can work together to solve problems and explore how the superpowers of bugs could be put to use for humans.
Heart disease kills almost two million people a year in the EU, so it is important to find different ways of keeping your heart healthy. This September, Horizon examines innovative ways of treating heart disease, including electric gene therapy to prevent heart attacks and a miniature heart implant. Plus, we look at how 4D imaging of mice and zebrafish can help regenerate human hearts.
The world is losing its trees, but at what cost? Better estimates of deforestation and degradation could shed light on the amount of CO2 emitted, refine climate models and help developing countries better manage their forests.
Understanding more about how solar storms interact with the outermost part of Earth's environment, known as the foreshock, could refine space weather forecasts to predict their effects at a local level and help protect vital technology, according to Dr Lucile Turc, a space physicist at the University of Helsinki, Finland.
New measurements of carbon emissions provide better estimates of deforestation effects.
Illegal logging is a billion-euro racket but trees have traceability built into their trunks.
Better space weather forecasts will help.
