Science journals are often the last bastions of the world’s traditional science, but some of them have seen their numbers decline.
Here are five articles that offer a warning about the future of science, and the importance of saving the world.

This study by the US Department of Energy suggests the world may need to rely on renewable energy for half of its energy needs by 2050.
The US is already using renewable energy to meet its electricity needs, and more are likely to follow in the coming years.
In 2016, the European Union launched the Energiewende, an initiative to increase renewable energy generation by at least 50 per cent by 2030.
That could mean at least half the EU’s power would come from renewables by 2030, as the EU is the world leader in renewable energy.
A study by MIT, published in the journal Environmental Research Letters, found that the amount of CO2 in the atmosphere has increased by 1.2 gigatonnes per year since 2000, and that the rate of warming is accelerating.
The study said that if global warming continues, it is likely that a “climate catastrophe” could occur within the next 100 years, due to CO2 levels being too high.
Scientists say that while climate change is a threat to humanity, the worst-case scenario is one in which global warming is 2 degrees Celsius or less.
The UN’s Intergovernmental Panel on Climate Change says that there is no realistic chance of avoiding a rise in global temperatures.
