Systemic racism is an issue so engrained within our culture that the effects of ones efforts can feel somewhat entirely negligible. So we must cast aside the pride of feeling as though our contributions shall change the world. Nevertheless, true selflessness is demonstrated most starkly when one cannot see the fruits of our labour. Inability to see the significance of the impact we make is no excuse not to make an effort. 
So, should we all make an effort to challenge prejudice in the field we feel most credible, then after such a collective movement of kindness, perhaps we will begin to see the systemic change required.
My niche feels to lie within the climbing community, of which I feel grateful for its kind characters and inclusivity. I know many are not so fortunate, but within climbing I have never experienced any hostility due to my ethnicity. With the exception of rare anomalies, I am content with the absence of active hostility towards ethnic minorities within our community. This is, without a doubt, the most common argument for one challenging change.
But the issue is far from over. It is a sad reality that our sport absolutely lacks diversity. So where does the issue lie? Well, to someone living in a world ripe with prejudice, peering into this community of weird and wonderful people scrambling up chunks of rock and plastic and quickly noticing the absence of ethnic minorities, how could they expect such a community to be anything but a reflection of the prejudice held by the broader society. Why would they even think to give it a chance?
So what feels to be the solution? I believe we require a critical mass of inclusion. Through a series of initiatives focussed on increasing accessibility, perhaps by wall entry subsidy or free events, and demonstrating visible inclusion, it is possible to bridge this gap and welcome all to a kind community. Before long, such inclusion could have a cascading effect once diversity of climbers begins to grow.
And this is the role of charities and movements such as Project 1. The beams to build our bridge.
