(Published October 2019) 14:00 — U.S. Farms Waste A Lot Of Water — But This Tech Could Help (Published September 2022) 29:56 — How The West Coast Drought Could Cause More ‘Water Wars’ (Published July 2021) 40:07 — Why Flood Insurance Is Failing The U.S. (Published November 2020)
Most of the freshwater is locked away in glaciers or deep underground. Less than one percent of it is available to us. So why can’t we just take all that seawater, filter out the salt, and have a nearly unlimited supply of clean, drinkable water? The western U.S. is experience a megadrought so severe, it is the driest two decades in at least 1,200 years. And no sector has felt the impact more than agriculture, which takes up about 70% of the world’s freshwater.
With water resources becoming more scarce, several companies are working to improve irrigation efficiency and help sustain food production in a future where extreme climate may be more common. Water is a cornerstone of economic activity, and when it runs low, communities face tough choices. The extreme drought conditions in the U.S. West are straining water resources and providing a fertile ground for wildfires. How will the West Coast face this climate challenge? And 2020 was the busiest hurricane season on record. Flooding is one of a storm’s most devastating consequences.
FEMA estimates one inch of flood water can cause up to $25,000 in damage. The U.S. began offering national flood insurance in 1968 but the program, called the NFIP, is now over $20 billion in debt. Private companies are starting to offer flood insurance as well. However, flood insurance is more complicated than it may appear. Watch the video to better understand how flood insurance works, and doesn’t work, in the U.S.

Germany is the leading or “framework nation” in what is called the NATO Battle Group Lithuania. With its alliance partners, German forces are serving “on the front line” – right on the Russian border. They’re guarding NATO’s northeast flank against any possible incursion and ensuring the Baltic states are supported during times of crisis and, if necessary, conflict.
In the spring of 2023, Germany’s military is in Rukla and Pabrade, among other places, for maneuvers. There it is practicing with NATO partners from Croatia, the Czechia and the Netherlands to handle a Russian attack on the Baltic states. In full agreement with the NATO motto “train as you fight,” practice and training are closely-oriented to a genuine threat.
The leader of the German contingent, Colonel Wolfgang Schmidt, points out the special historic significance and perceived peril in the Baltic. He says, “From historical experience, of course the perception of possible aggression – be it Russian or Belarusian – is far more intense here than in the Federal Republic of Germany.” He adds that not everyone has grasped the defense of “all that we stand for – modernity, freedom of opinion and speech and everything we describe as Western values begins here.” For a year, Schmidt says, the Ukraine has been fighting far more than their Russian attackers – they’re defending “our freedom,” too. This report follows a major exercise called “Griffin Lightning.” A platoon commander with the Dutch Armed Forces emphasizes the importance of maneuvers and cooperation among the multinational forces.
First Lieutenant Bent S. says, “We’re taking part in different exercises. Last week we were with the Norwegians. In a few weeks, the whole Battle Group will come together and we’ll train again with the Norwegians, Germans, Czechs and Croats. Nobody wants war, but if it really comes to it, we’ll be ready.” This documentary provides an exclusive look at NATO maneuvers in Lithuania, which are unfolding closer than ever before to a genuine military threat.
