As the impact of climate change becomes clearer, experts say the world needs to do more than just stop producing greenhouse gases. Aggressive steps also must be taken to pull them out of the atmosphere. While engineers puzzle over high-tech solutions, scientists say nature offers tools today. The world's grasslands can soak up tons of carbon dioxide. VOA's Steve Baragona visited a Texas cattle ranch working to restore overgrazed land so it can join the fight against climate change.
The World Health Organization (WHO) says a campaign to distribute anti-malaria drugs to children in Nigeria's Borno state seems to be making an impact, with fewer cases reported. Nigeria is still the world's highest malaria-burdened country with 25 percent of all cases worldwide. As Timothy Obiezu reports from Maiduguri, there's still far more that needs to be done to check the spread of the disease.
