Reasons Why Water is Vital for a Sustainable Future

There are many things that are challenging the world today, and it is important that we start addressing them right now, so that in the future things won’t get too bad. Amongst the things that are challenging us include climate change, food security, infrastructure, energy, water and sanitization, urbanization and food security. This is why it is important for us to understand the big role that water plays, since one way or the other, it affects all of the mentioned things. We are going to look at some of the reasons why water is vital for a sustainable future.

Health and disease

There are many water related diseases such as diarrhea and amoeba, and this is because very many people the world over lack adequate sanitation facilities and defecates openly. That is costing the world a fortune, and especially if you take into consideration that almost 800,000 children die of diarrhea yearly due to unsafe water, poor sanitization and hygiene standards.

Malnutrition and child development

Safe drinking water and adequate sanitization are things that not everyone has access to, and especially in third world countries. These two even beat insufficient food when it comes to malnourishment. This has led to a stunt in growth since the nutrients and energy that children have are not directed at growth and development in a bid for survival.

Gender equality

According to surveys, women and children from some developing countries spend up to 40 billion years bearing the burden of fetching water. Almost 2/3 of the households in those places don’t have a source of drinking water on the properties.

Sustainable Energy

Countries that have water also need to look for ways of getting a sustainable energy source such as solar and wind. One example of the countries that have more than enough water but are still hit by water shortages is Brazil. More than 70% of their water is hydrogenated and yet they always have water shortages.


Deforestation and pollution are some of the things that are brought about by urbanization. This means that the rainfall reduces, the water reservoirs in growing cities running out of water.

Reasons Why Water is Vital for a Sustainable Future

Agriculture and Food Security

By the year 2050, production of grains would drop by almost a half because of water stress. This is something that could be faced more by developing and emerging communities. In 2014, drought affected California, the worst in a century. The same happened to Australia, and the government had to limit the water allocation to rice farmers.

Peace, Security and Climate Change

The rate at which greenhouse gas emissions increasing is alarming, and if the situation continues that way, we could be facing the biggest ever drought in the near future, even lasting longer than 35 years. That could lead to instability like the one witnessed in Syria between 2007 and 2010, most likely brought about by climate change. That is what is considered as the root cause of their current conflict.

The Best Water Filters

Now that we have been talking about why water is vital for sustainability, we might as well talk about water filters since they are an important part of the water that we use and consume. These reviews are based on the Pure Water Patriot, and they are aimed at helping you choose your next water filter. These reviews are done based on cost, performance, installation and the filter life.

Reverse Osmosis Water Filters

This is the perfect filter for eliminating all sorts of particles from the water, whether they are solid or dissolved. Water passes through a semipermeable membrane, the tiny holes trapping the smallest of particles. Initially, it filtered salt water from the sea, turning it into fresh water. Over time, the system has been improved into a 5 stage process to remove contaminants from water.


  • A superior process that extracts contaminants
  • Pure water on demand straight from the faucet
  • Low maintenance


  • Wastes quite a lot of water
  • Removes beneficial minerals and you would have to buy them to add them back

Whole House Water Filters

These water filters work best with the reverse osmosis system, working in two stages. It starts with a multi-gradient polypropylene sediment filter with different inner layer thicknesses that filter out most organic and inorganic matter. A catalytic carbon filter comes next, removing chemical contaminants from the water.


  • Every faucet and water outlet produces pure water
  • Once installed, aside from regular filter changes, it requires no maintenance Filters are long lasting
  • Little effect on water pressure


  • May need to be installed by a plumber
  • Hard to tell when filters need replacing

Counter Top Water Filters

Just because water looks clean, doesn’t mean that it is healthy it could contain impurities, and that is what brings about the importance of countertop water filtration system. They remove chlorine as well as other chemicals that are found in the water supplied by cities. The replaceable carbon cartridge ensures that all the contaminants are kept out of the drinking water.


  • Removes impurities
  • Easy to install and fits most faucets
  • Fast flow rate
  • Better performance as compared to pitcher water filters


  • The unit has to be on show
  • No water chilling option

Faucet Water Filters

This is the perfect option for those that don’t want to incur the high expense or tougher installation filters. With this simple system, one has to simply remove the aerator from their faucet and install the unit into the hole. These filters can go for almost three months before they need to be replaced, although it also depends on the amount of use given to them. They have indicators to show when they need to be changed. Water is pushed through the carbon filter by the water pressure.


  • Removes 10 times more contaminants than pitcher water filters
  • Easy to install
  • Easily replace filter
  • Is affordable


  • Doesn’t fit all faucet types
  • Slows water flow

Under Sink Water Filters

These are installed under the sink, filtering the water that moves through the pipes before exiting the faucet whenever one turns on their taps. It removes impurities from the water such as herbicides and parasites. It also brings down the amount fluoride, heavy metals and organic chemicals, improving the quality of the water. One problem to note is that installation may require a plumber since it could be tricky.


  • The fact that it is under the sink means that the kitchen remains clutter free
  • Large daily output producing lots of filtered water
  • More durable as compared to countertop filters


  • Installation can be tricky and may require the services of a plumber
  • Albeit being more durable, they are more expensive

Gravity Fed Water Filters

These are effective water filters that use two or more carbon filters to remove toxic elements and heavy metals from water. They are effective because the water and the filter media have a high contact time. They are easy to assemble, and do not rely on power to work, but gravity, whereby water is filled into a tank, the gravity letting the water flow through the filter before it is gathered in another tank.


  • Simple and efficient to use
  • Turn any unreliable water source into drinking water
  • No plumbed water supply needed
  • Long lasting filters


  • Replacement cost for some of the filter components can be expensive (take care when handling)
  • Relatively slow water output


Water is an important factor when it comes to sustainability, because it affects many things. On the other hand, if you have it in your home or office, you might want to consider getting a water purifier to make sure that you’re taking healthy water. Don’t risk your health when you can get any of the water filters reviewed above to keep the impurities away.
