<p>For the next four weeks, we'll be featuring a relevant part of an interview with one of five Solver teams. They represent very different solutions and talk about their work in very different ways. To start off, let's hear from Diana Yousef from <a href="http://www.change-water.com/" target="[object Object]">change:WATER Labs</a>, a Solver team from 2019.</p>
<p>In the video below, Diana describes an Impact Opportunity relating to the <a href="http://www.change-water.com/problem" target="[object Object]">problem of poor sanitation</a>. This problem has a global scope that affects billions of people, and her social enterprise has been focused on solving this problem through the use of portable toilets. As you watch this interview, take note of how Diana explains the problem, briefly cites evidence, and highlights change:WATER Labs' offering.</p>
<p>Diana presents a clear Impact Opportunity, with all three main components – it can be hard to cite sources in video. You can hear more from Diana in a <a href="/courses/course-v1:MITx+0.SolveX+2T2021/jump_to_id/9edf7d0ef3514a5aa48afc2e71cee1e0" target="_blank">library of videos here</a>, and we will explore interviews from this video library in future weeks of our course.</p>
<p>If you would like to see how Diana described this Impact Opportunity when applying to Solve, please consider reviewing her <a href="https://solve.mit.edu/challenges/healthy-cities/solutions/9244/application" target="[object Object]">example application</a> from 2019.</p>
