Helium is also used(in combinations of breathing gases for deep-sea diving replacing nitrogen gas, which can hake people'sick at high pressures. Helium is collected as a by-product of the oil and gas industry. In the 1920s, the US government began to store helium at the National Helium Center (NHC), to_use in military flying machines. By the 1960s, the US military had new uses for helium, such as cleaning fuel tanks for rockets. By the 1990s, the NHC was in enormous debt from storing helium, so a law was passed in 1996 forcing the NHC to sell all of its helium by 等、 2A15 no matter the market price

Wales is a small but progressive country, the only country in the world to have legislated to protect the interests of future generations, the only country to have appointed someone independent to oversee this. Across the world, our systems of government, of politics, of economics have tended to act in the short term. And often, the decisions that are taken discount the interests of future generations and the planet. But in Wales, we're trying to change that by passing a law which requires not just our government but all of our main public institutions to demonstrate how they're acting for the long-term and how the decisions they take don't harm the interests of those yet to be born. And so as a mum of five and the world's only future generations commissioner, I want to share with you today some of the lessons we've learned about how we're trying to leave the world better than we found it. First of all, you must involve people in setting long-term goals. Ask them: What's the Wales or the world you want to leave behind to your children and your grandchildren? We held a national conversation -- the Wales We Want -- and people told us, "We want a low- carbon economy. We want you to help us keep people well rather than just treat them when they're ill. We want connected communities and a more equal Wales." And our government legislated to set seven national well-being goals to achieve that. Each institution has to demonstrate how they're meeting those goals, and they're held to account by me. You have to focus on the interconnections between different aspects of well-being. You need to talk often about why it's just as important to public health as it is to the environment to tackle high levels of air pollution, why diversity in the workforce is just as important to economic prosperity as it is to addressing inequality. Our institutions have a legal duty to act beyond their immediate remit to recognize those connections, work with unusual suspects. And so we're seeing hospitals in Wales working with the National Botanic Gardens to create spaces for nature on their sites. We're seeing offices in our environmental agency helping to find solutions to tackle childhood
