'America, send us your ideas': Biden pledges to protect 30% of US lands by 2030

To reach this conservation goal, the country will have to conserve more than 400m acres of land and waterways in the next 10 years

It was an executive order that made waves in environmental circles: after only a week in office, President Joe Biden pledged to preserve 30% of US lands and waters by 2030.

The so-called 30 by 30 conservation goal has already met with bipartisan support in Congress, and it aligns with science-based global preservation targets to reach an eventual target of 50% by 2050.
