This is the only genuine question I found in the comments here & I just came from teaching on this topic for our incoming class of forest & rangeland students so here is one person's take on what it can mean to #DecolonizeScience... https://twitter.com/johndawkins/status/1300874213625008128

To #DecolonizeScience is to approach science and knowledge making in a way which engages with the underlying colonial historical context, to form a critical understanding of the underlying assumptions, motivations, and values that inform science education and research

To #DecolonizeScience is also a means of shifting our focus towards healing and regenerating Indigenous lifeways (to inform all lifeways)

There are many other sources, readings, interpretations, and case study examples beyond this you can reach via Google. I'd start here for required reading though: https://www.zedbooks.net/shop/book/decolonizing-methodologies/
