Exploring the link between water conservation and climate change
Water is all around us. In the sky, in the sea, in our faucets, in the food we eat. It’s a vital resource – but there’s not an unlimited supply. It’s often the case in many parts of the world that we have too much or too little water, with flooding and droughts both being major issues across the globe.
But why does this happen, and what’s the link with climate change? And how can water conservation habits help? In this blog post, we explore this important issue.
What impact does climate change have on water levels?
According to the UN, “climate change is primarily a water crisis”. Sea levels are rising, which in turn causes flooding; then wildfires and high temperatures are damaging trees and other vegetation which we rely on to soak up groundwater and shore up our soil. The world is designed in perfect harmony, with each part of the ecosystem doing its job, so when high temperatures push things out of balance, it has a knock-on effect.
Additionally, all the water we drink tends to come from reservoirs, streams, lakes and other pools. When it’s very hot, there’s less water in these sources, which can lead to a water shortage. It’s all linked.
Why should you be conscious about your water usage?
Does a dripping faucet really matter? Does a shorter shower make a difference? Why should you use a watering can rather than a hosepipe?
Little changes in our homes can often feel insignificant in comparison to the scale of the wider climate crisis. However, every little bit helps. For context, data from the United States Environmental Protection Agency shows:
The average family in the US uses 300 gallons of water per day at home
70% of this is from indoor water usage
A shower accounts for about 20% of your water usage
Leaks account for about 12%
The research goes on to show that strain on water supplies can lead to:
Increased water costs
More regular watering restrictions outside
Loss of lakes and rivers that provide entertainment and employment
A need for expensive water treatment plants
It’s clear then that we all have a part to play in managing our water use – every little bit you can save adds up to make a difference.
Additionally, every bit of water that enters the average home is treated and checked. If you increase the amount flowing through the pipes every year, you increase the amount of energy needed to run these treatment works. This energy is potentially produced using greenhouse gases, which is then fuelling climate change. So, we all need to be sensible so that we’re using the right amount of water, rather than too much.
How can you reduce your water usage?
Ready to make some positive changes and cut down on your water usage? Here’s how.
Make sure you fix any leaks
As we’ve mentioned, leaks can account for around 12% of your water usage, so fixing any dripping faucets should be high on your priority list.
If you’re a confident DIY enthusiast, you can easily fix a faucet yourself by searching online for a video tutorial – just make sure you know how to turn off your water first to avoid any accidental flooding in your kitchen. Alternatively, call a professional to do the job for you.
Use cold water where possible
You might not think of it, but hot water uses more energy to generate than cold water, and usually you’ll leave the faucet running while it gets to temperature, sending water down the drain.
If you prefer to let the faucet run to get icy cold water, try filling a jug and keeping it in the fridge instead. This way, you can get a refreshing drink without wasting water.
Only run appliances when they’re full
You might be in the routine of running the dishwasher or washing machine every night, but this means you’re using more water than you need. On the opposite end of the scale, you might think you’re saving water by handwashing your dishes, but this isn’t always the case with modern dishwashers.
The best way to use these appliances is to only run them when they’re full, and save handwashing for just a few items. In this instance, use a bowl within your sink to avoid running a full basin of water for just a few cups or plates.
Make a difference
There are so many ways that you can reduce your water usage, and in turn, reduce your climate impact. Try and get into the habit of turning off faucets and being more conscious of your water usage and you’ll see a difference in your carbon footprint and your bills in no time.
