Water is one of the basic necessities of life, which we use almost without thinking, and this can lead to significant waste. While we're always advised on how much water we should drink daily, we don't really hear much about the amount of water we are wasting, water scarcity, or how we can reduce usage. This World Water Day, we speak to Norizan Mohd Mazlan, the Head of Conservation in Peninsular Malaysia at WWF-Malaysia, about major issues that must be addressed to ensure the sustainability of our water resources here in Malaysia.
