Example: When providing health care, a doctor is obligated to use the collected data to help the patient; not for manipulation or reselling.

Climate change is scary, but we can’t afford to succumb to defeatism.

If politicians invest just an extra 2% of Global GDP in developing eco-friendly technologies, like solar & wind power, we could shield the world’s developing nations from worsening storms, floods & droughts. Currently, governments are failing to collect huge sums of money that are hidden away in tax havens by corporations and wealthy individuals. Every 4 years, the equivalent of 2% of annual Global GDP is lost through tax evasion.

In 2020, 2% of Global GDP was US$1.7 Trillion. That sounds like a lot of money, but it’s a small slice of the pie.
If politicians invest an additional 2% of Global GDP in clean energy, this would be enough to prevent the most catastrophic climate change scenarios. Here’s another example to show why there’s room for optimism about our future:
Based on the current price of rainforest land in South America, a one-time donation of 1% of annual Global GDP would let local conservationists turn the entire Amazon into a protected nature reserve.

It’s easy to get pessimistic about ecological collapse and its complex challenges. But when you dig into the numbers, a different story emerges. It turns out that if humanity invests an extra 2% of Global GDP in developing eco-friendly technologies and infrastructure every year… ImageImageImageImage …this would be enough to prevent catastrophic climate change. That’s less than what politicians spent on the military in 2020. And it’s the annual investment that can get us to a carbon-neutral economy by 2050.
