Like most major problems, the wastewater problem needs to be solved through a collective effort. The best way we can contribute towards that effort is to:
Conserve Water: The less water we use, the less wastewater we’re going to produce. A few simple ways we can do so is by fixing indoor leaks, reducing shower time, and by avoiding any wasteful washing habits. Switching to water-saving appliances will also help minimize the amount of wastewater produced. This helps water treatment plants process better because if there’s less wastewater, the quality of treatment will be better.
Minimize The Polluting Content Of Wastewater: The other factor that makes wastewater so harmful lies in the variety of chemicals that mix with human waste and food scraps. This can be averted by choosing the products we buy carefully. A good example of this is by using only low-phosphorus household products in order to reduce phosphate levels in wastewater.
Innovative Decentralized Water Technology: The decentralized technologies are Ecological Sanitation consisting of Septic Tanks, Constructed Wetlands, Composting Toilets, Biodigestor, Anaerobic Filter etc. These decentralized systems include the possibility for reusing the effluent and the potentiality for aquifer recharging. A problem in a unit doesn’t collapse the whole system. The local potentialities can be developed as small systems can be designed, built and managed by a local professional, improving the local economy.
Wastewater Regeneration Technologies: We need to create a self-sufficient treatment plant where the energy required for the plant is produced in the plant itself via the obtainment of biogas or other renewable energies.

Almost six years into the Sustainable Development Goals (SDGs), but the world is still far away from ensuring a quality education for all by 2030.
As COVID-19 cases rise and fall many education systems around the world are reopening fully, partially, or in a hybrid format, leaving millions of children to face a radically transformed educational experience.
Here are some insights into supporting immediate and long-term goals for educating children.
Support caregivers at home to help children learn while schools are closed.
Many parents or caregivers, especially with young children, have taken on new roles to help with at-home learning. To support them and remote education efforts, many LMICs have used SMS, phone calls, and other widely accessible, affordable, and low-technology methods of information delivery. While such methods are imperfect substitutes for schooling, research suggests they can help engage parents in their child’s education and contribute to learning, perhaps even after schools reopen. Other governments and organizations in areas where internet access is limited are also experimenting with radio and TV to support parents and augment student learning.
As schools reopen, educators should use low-stakes assessments to identify learning gaps.
Rather than jumping straight into grade-level curriculum, primary schools in LMICs should quickly assess learning levels to understand what children know (or don’t) and devise strategic responses. They can do so by using simple tools to frequently assess students, rather than focusing solely on high-stakes exams, which may significantly influence a child’s future.
Tailor children’s instruction to help them master foundational skills once learning gaps are identified.
Given low learning levels before the pandemic and recent learning loss due to school disruptions, it is important to focus on basic skills as schools reopen to ensure children maintain and build a foundation for a lifetime of learning. Decades of research also shows that tailoring instruction to children’s’ education levels increases learning.
As countries rebuild and reinvent themselves in response to COVID-19, there is an opportunity to accelerate the thinking on how to best support quality education for all.

Adverse health impacts can be indirect or invisible. Innovation that supports the whole community and tackles existing inequalities can improve people’s health and livelihoods in the long-term.
Solar-powered ice flake machine with an integrated water purification unit aims to bring cold chain management services to local areas, so that people fishing can do so for longer.
In fishing communities in Kenya, men are mainly responsible for fishing, while women carry out the post-harvest processing. This includes drying, smoking or deep-frying the fish. Unfortunately, this reduces the market value of the fish, and means it cannot be exported to overseas markets.
Solar powered ice flake machine will help keep the harvested fish fresh for longer, increasing the economic value of the fish.
At a community level, investment into improved food and job security can contribute to better overall health. Currently, fishermen can lose 25% of their stock due to poor storage. This project will benefit fishing communities in Kenya by reducing post-harvest fish loss. It could also help to grow the fish market and provide employment opportunities for women and youth. Keeping food fresh for longer will increase food security and reduce the likelihood of malnutrition, which 26% of children in Kenya currently suffer from. Improved employment, income and food security can all help people avoid going hungry and improve their overall health.

Transitioning: Many families dealing with poverty need help transitioning into a state of self-dependance. 15 Feeds Family is an organization that helps with this transition. They start by providing families with food, but then slowly find solutions to empower families to be self-sufficient. This is important, because self-sufficiency allows for a certain food income, when relying on donations does not always guarantee food.
Precision Agriculture: Advancements in precision agriculture, a farming management concept that incorporates internet of things (IoT) technology into farming techniques, offers another way to help feed the planet.
Gene-Edited Crops: Gene editing is essentially a much quicker form of breeding. New companies are being set up to help evolve the nutrition of food with the promise of delivering high quality, trusted ingredients that are traceably produced for complete transparency. The powerful new gene editing technology known as CRISPR allows researchers to correct genetic defects, treat and prevent the spread of diseases and improve crops. The latest advancements could result in healthier food alternatives for consumers with the same great taste that they love.
Urban Farming: Almost one-quarter of undernourished people live in an urban environment. Recently, there has been a big push for urban farming. It empowers families to gain control over their own food source. Moreover, it brings farms closer to where people live, this farming method is expected to be both efficient and cost-effective by reducing transportation expenses.
Food Donations: The impact of donations, both cash and food, have had an immense impact on world hunger. Organizations such as Food for All have customers donate $1-5 when checking out. Last year they raised a whopping $60 million to fight world hunger.

Energy efficiency reduces the effects of pollution and is also seen as a solution to the problem of minimizing greenhouse gas emissions. Energy efficiency isn’t just easier on the environment; it also saves you money!
Here are some things that can be used to make our home more environment friendly and energy efficient.
Smart Power Strips: Cut down standby power with Smart Strips, it allows you to connect multiple appliances to a single electrical outlet. Though with traditional power strips, devices plugged in often consume electricity even when you aren’t using them. This results in larger electrical bills and poor home energy efficiency. Smart power strips solve this problem by cutting power to connected items in standby mode.
LED Lighting: If you’re still using regular fixtures and bulbs, switching to LED lighting could greatly reduce your monthly energy bills. Aside from increasing your energy-efficiency and containing none of the toxic chemicals that most other light bulbs do, LED bulbs have a much longer lifespan and can be used for up to 100,000 hours before they need to be replaced.
Smart Thermostats: The thermostats work by adjusting the temperature in your house based on whether or not you’re home, and which rooms are in use. Smart thermostats help users take anywhere from 10 to 15 percent off their heating and cooling bills.
Energy Efficient Plumbing: Energy efficient toilets provide another excellent way to reduce your energy consumption, this time by saving water. If your toilet was made earlier than 1994, replacing it with a high-efficiency model can save you more than 4,000 gallons of water per year.
Energy Saving Apps: Energy Saving Apps like Homeselfe ask a few quick questions about your energy habits, and then generate a comprehensive report that provides ideas on how to improve your efficiency.

There are a lot of items that we use everyday and then get rid of them by throwing them in the garbage. Unfortunately, this results in piles of garbage increasing waste in landfills further causing a number of issues.
Landfill waste poses a huge problem as it has economic and environmental impact and secondly, due to slow decomposition rate which takes thousands of years, several acres of land has already been virtually rendered useless that could have been actually used for setting up new residential colonies or industries. Here are some simple changes you can make to reduce waste in your home:
Save Leftovers for Next Day. Too many people are careless enough to throw away half of a good meal and not save it for later. Eating leftovers more often will save on money and result in less food waste.
Donate Clothes, as throwing away of clothing is one of the biggest contributions we make to landfills today. Instead of throwing away these old clothes, make better use out of it.
Start composting, it is an easy and natural process that takes the remains of plants and kitchen waste and turns it into nutrient rich food which helps your plants grow. It helps you recycle your kitchen waste and reduces the amount of that is sent to landfills that proves safe for the environment.
Start relying on reusable containers. Once you start buying only what you need, take it to the next level by storing food properly, which will extend its life and keep things fresh for as long as possible.
Learn to repair rather than discard.
Ditch the plastic bags and at the very least, stop buying plastic water bottles.
Switch to Rechargeable batteries. Rechargeable batteries will save you money in the long run and keep disposable batteries out of landfills. Disposable batteries can prove very harmful for the environment as chemicals inside the batteries can leak.
Diverting waste away from landfills can help prevent pollution that harms our health and the environment.

The global water crisis has many causes, requiring many different solutions. Drinkable Book is one of the solutions.
It’s the first ever manual that provides safe water, sanitation, and hygiene education — all in one!
A group of researchers from the US, in collaboration with a non-profit organization, has designed a book with silver-impregnated pages that can be used to filter contaminated water. One page from this ‘drinkable book’ can potentially filter up to 100 liters of drinking water and may provide a cheap, sustainable solution for communities suffering from severe sanitation problems.
Each page of the book provides basic water and sanitation advice, such as the importance of keeping contaminants like rubbish and feces away from water, often unknown in developing countries.
