Nigeria is struggling to end open defecation, but a grassroots campaign is trying to change that

Billions of people around the world lack access to safe sanitation, causing disease and deaths. In Ecuador a foundation developed a cheap, dry, composting toilet for poor rural families.

The Flint crisis displayed the deficiency of knowledge by medical doctors to environmental health concerns. In response, the national medical community is bringing more awarenesses and education to current and future doctors about the importance of long-term effects of the environment on health. More research in this area is necessary as well as more classes in medical schools. Universities across the U.S. are now developing such courses to change the future of patient care and crisis prevention.

The Brownfields Program, funded through the EPA, helps towns across Montana redevelop contaminated buildings into new areas for economic development. Since 2016, when Anaconda and several nearby towns became eligible for this funding, they have used federal funds to clean up petroleum spills and other leaks and create new locations for community life to flourish.

Uganda’s education ministry requires all schools to have incinerators to burn used sanitary pads. Lack of funding limits schools’ ability to comply. Even when incinerators exist, girls don’t necessarily use them. Educating both girls and boys about menstruation reduces stigma and increases the likelihood that girls feel comfortable enough to collect pads instead of throwing them in pit latrines.

Across the country, projects that mine landfills for reusable metals and soils are underway. Can such mining prove profitable enough to spur similar efforts on a grand scale? So far, some projects have seen profits while others have not. But as society increasingly values pollution and greenhouse gas reduction, incentives for refuse mining can only grow.

Innovative mine reclamation projects across five states in the Appalachian region allow local organizations, schools, and businesses to clean up and utilize abandoned mine land. From a school that's transforming abandoned mine land into a field of solar panels to a housing development project that uses abandoned mine federal grant money to build affordable and energy efficient housing, the Appalachian region is using a comprehensive approach to renew blighted mines.

The simple addition of adding handles to bathroom stalls in the Rohingya refugee camps in Bangladesh has helped the camps' pregnant women regain a sense of empowerment and dignity. Providing support and balance, the design of these latrines have benefited the elderly in the camps as well.

On World Toilet Day in 2014, the Kenyan government promised to build 180 public toilets in an ambitious move to combat the issue of public sanitation. The program went well once the keys were handed off to the National Youth Service of Kenya as a means of income, but issues quickly arose that could not be resolved because of a lack of further funds. The youth has since transformed their toilets into a rental space for local churches, such as Christ Miracle Church for All Nations in Laini Saba.

The state of Pennsylvania set to plant 86,000 hectares of riparian buffers, the practice of planting trees and shrubs along a river or stream to filter water. Other benefits of riparian buffers include things like restoring the soil and cooling the water. In order to meet their goal, the state scientists used a bottom approach, enlisting the help of local farmers by offering them grants to plant trees and showing farmers how they can profit off of riparian buffers. While the state is behind its goal, the state is planting about 1,000 to 2,000 hectares a year.

In 2020, a devastating explosion in Beirut that came from a warehouse released 800,000 and one million tons of construction and demolition waste and 20,000 tons of shattered glass into the city. The waste was being thrown into landfills. However, landfills are notoriously bad for the environment. Out of that rubble an idea was created; disposing waste sustainably. Rubble Mountains was created specifically to do this. They've been able to restore four quarries, use materials to create public amenities, and diverting up to 50 tons of demolition waste from landfills.
