This article aims to make the reader aware of the amount of energy used to produce water by the process of reverse osmosis in dry countries like Malta. It also investigates the ways in which energy is conserved during this process and gives sugestions to readers on how to save water in order to save energy.

Water – An Existence

A dam is a barrier that impounds water and is constructed from a variety of materials such as rock, wood, steel and concrete. It serves the primary purpose of retaining water, to manage or prevent water flow into specific land regions and furthermore to collect water or for storage of water which can be evenly distributed between locations. The picture shows the Chadwick Lakes water reservoir filled to the brim after heavy rainfall. This early dam system was constructed in 1886 under the direction of Sir Oswald Chadwick with the intention of using this magnificent resource in a more sustainable manner.

Beach Erosion

This photo shows the effects of coastal erosion at Għajn Tuffieħa. Erosion occurred rapidly here recently due to human intervention, including deforestation. To counteract the effects of coastal erosion, more vegetation was grown at Għajn Tuffieħa in the 1960s. One can also note the man-made staircase constructed directly on the sand dune and also two horrendous structures at the back. In some coastal areas, the sandy terrain is eroded and disappears over time. This occurs when sand is lost at a faster rate than it is replaced. Sand is lost when sediment and sand grains are blown or carried away by strong winds, waves and stone from the coast. Plants and scrub vegetation hold the sand particles in place. Lack of sand dunes therefore increases beach erosion. Sand is added to the beach by soil which crumbles and is carried by the wind and deposited on the coast.

Are we heading towards a sustainable world?

The first thing that one would say about this picture is that there is nothing wrong in it and it is one of the most amazing beaches in the island. But only some would notice that the street on the right of the picture is destroying the natural habitat and the beach. If you would ask a person of an elderly age you would find that the street wasn’t always there but the water would keep going in to where we now find the natural reserve. By building this street we destroyed the sand dunes and now when ever you pass on a windy day you could see that this is true since the sand would create small dunes on the street. Are we really heading towards a sustainable world? I think the answer is no. WE shouldn’t continue on building these kinds of streets if we are aiming to get a sustainable world.
