Adding to climate change- water management. Cape Town, South Africa had over 10 years to find a solution to their water problem but delayed. I read that Bangalore, India might have used up to 80% of their groundwater... Water management can be solvable and lack of clean water affects 2 billion people. Not only that but climate change will dramatically affect coastal cities and couple hundred more million people especially in Asia. I've been researching water management lately trying to figure out what potential solutions I could work on but haven't figured anything out yet. There are sensors for identifying leaks or testing water. Better graphene filters for desalination. Problems with microplastics/pharmaceuticals in tap water that might be able to be fixed through reverse osmosis (RO) systems... I've considered importing a bunch of RO systems and starting an RO business to learn more. I recently learned that there might be 6 carcinogenic chemicals in New York City tap water that is unregulated and a byproduct of the bleach they use to sanitize the water... Water management is directly connected with population growth. When people move due to water scarcity or conflict from water scarcity it will only exacerbate cities more. Currently reading The Big Thirst and looking forward to reading Living with Water Scarcity.
