By Depression can affect people over long periods of their lives. Some people experience this condition continuously, while for others, it occurs in episodes – with long stretches without symptoms. But when do people tend to experience it for the first time?The age when people experience depression for the first time is called the ‘age of onset.’ But this can be measured in different ways. One way is to find out when people first had the symptoms of depression. This is done by interviewing them about symptoms they have had in their lives so far – some people describe...…By Depression can affect people over long periods of their lives.

It is easy to underestimate how much the world can change within a lifetime. Bringing to mind how dramatically the world has changed can help us see how different the world could be in a few years or decades. by Max Roser February 22, 2023 Technology can change the world in ways that are unimaginable, until they happen. Switching on an electric light would have been unimaginable for our medieval ancestors. In their childhood, our grandparents would have struggled to imagine a world connected by smartphones and the Internet. Similarly, it is hard for us to imagine the arrival of all those...…It is easy to underestimate how much the world can change within a lifetime.

Putting a price on carbon helps us account for the real costs of fossil fuels in the market. Which countries have a carbon tax or trading system?The true cost of burning fossil fuels is not reflected in their market price. People often compare the monetary price of fossil fuels to low-carbon alternatives such as renewables or nuclear energy. But these comparisons do not capture each option’s social impact, even in a purely economic sense.Burning fossil fuels drives climate change. The impacts of climate change come at a cost – these impacts are already happening.They also cause local air...…Putting a price on carbon helps us account for the real costs of fossil fuels in the market.
