<p>To our community,</p>

<p>On our journey to connect the world, we often discuss products we're building and updates on our business. Today I want to focus on the most important question of all: are we building the world we all want ?<p>

<p>History is the story of how we've learned to come together in ever greater numbers -- from tribes to cities to nations. At each step, we built social infrastructure like communities, media and governments to empower us to achieve things we couldn't on our own.</p>

<p>Today we are close to taking our next step. Our greatest opportunities are now global -- like spreading prosperity and freedom, promoting peace and understanding, lifting people out of poverty, and accelerating science. Our greatest challenges also need global responses -- like ending terrorism, fighting climate change, and preventing pandemics. Progress now requires humanity coming together not just as cities or nations, but also as a global community.</p>

<p>This is especially important right now. Facebook stands for bringing us closer together and building a global community. When we began, this idea was not controversial. Every year, the world got more connected and this was seen as a positive trend. Yet now, across the world there are people left behind by globalization, and movements for withdrawing from global connection. There are questions about whether we can make a global community that works for everyone, and whether the path ahead is to connect more or reverse course.</p>

<p>This is a time when many of us around the world are reflecting on how we can have the most positive impact. I am reminded of my favorite saying about technology: "We always overestimate what we can do in two years, and we underestimate what we can do in ten years." We may not have the power to create the world we want immediately, but we can all start working on the long term today. In times like these, the most important thing we at Facebook can do is develop the social infrastructure to give people the power to build a global community that works for all of us.</p>

<p>For the past decade, Facebook has focused on connecting friends and families. With that foundation, our next focus will be developing the social infrastructure for community -- for supporting us, for keeping us safe, for informing us, for civic engagement, and for inclusion of all.</p>

<p>Bringing us all together as a global community is a project bigger than any one organization or company, but Facebook can help contribute to answering these five important questions:</p>

<p>My hope is that more of us will commit our energy to building the long term social infrastructure to bring humanity together. The answers to these questions won't all come from Facebook, but I believe we can play a role.</p>

<p>Our job at Facebook is to help people make the greatest positive impact while mitigating areas where technology and social media can contribute to divisiveness and isolation. Facebook is a work in progress, and we are dedicated to learning and improving. We take our responsibility seriously, and today I want to talk about how we plan to do our part to build this global community.</p>

<p>It's an honor to be on this journey with you. Thank you for being part of this community, and thanks for everything you do to make the world more open and connected.</p>
