Mathilda,15, is Turkana, a native people that has survived by raising cattle in a semiarid   region.  Mathilda's school, like most schools in the area, doesn't have access to clean water and sanitation facilities for its students. So instead of spending their whole school day learning, Mathilda and her classmates start their day by spending two hours to the closest river fetching water ---water that is anyway most likely not safe to drink. They do the same thing again in the afternoon, so they often lose around half of their school day fetching water. Mathilda has to do the same thing outside of school hours to get the water her family needs at home, leaving her little time for studying. Because of rising temperatures, water has become harder and harder to find here, and people have to spend more and more time trying to find it. This is just one small example of how climate change is making it harder to realize people's rights to water, education and security. Unfortunately, most higher-income countries remained silent on the issue. This is despite studies showing that communities already facing marginalization ,such as women and children, mostly suffer from climate change. This is especially the case for those in countries with limited resources and fragile ecosystems. Meanwhile, women consist of the majority of the world 's poor,and so are more dependent for their livelihood on natural resources that are threatened by climate change. And around the world, women and girls are the most likely to be responsible for fetching water for their families. This exposes them to danger and leaves them with less time to attend school, earn money, or simply to rest. But the fact is that the effects of climate change will be felt globally. Despite the difficulties she is facing, trying to get an education, Mathilda says she hopes to serve her community in a leadership role when she grows up. "All of the world's leaders need to work together to solve this problem that we are all facing," she said. We can conclude from the passage that  _  .
