In a world shaped by growth, consumption, and convenience, two materials quietly dominate our lives more than any others: water and concrete. One gives life, the other gives structure. But both come at a cost — one we can no longer afford to ignore. As climate challenges mount and resources grow strained, we must shift our relationship with these vital commodities. Here’s how.


Water: The Essential Commodity

Water is the number one most-used resource on Earth — not just for drinking, but for agriculture, sanitation, manufacturing, and energy production. The average person in the developed world uses between 100–300 litres of water per day, often without realizing it. From showers and toilets to dishwashers and lawn care, our habits have been built on the assumption that water is infinite. It’s not.

The Problem

  • Over-extraction of groundwater is causing aquifers to dry up.
  • Agriculture consumes up to 70% of global freshwater, often through inefficient methods like flood irrigation.
  • Climate change is shifting rainfall patterns and reducing snowpack, which many regions depend on for freshwater.
  • In places like Spain, poor water management and privatization are leading to overcharging, waste, and scarcity.

Solutions: Reducing Water Consumption

  1. Harvest Rainwater: Collecting and storing rainwater can significantly reduce dependence on municipal sources.
  2. Greywater Recycling: Reusing water from sinks, showers, and laundry for garden irrigation.
  3. Composting Toilets: These eliminate water use for flushing entirely — a game changer in off-grid and dry regions.
  4. Efficient Irrigation: Drip irrigation systems can cut water use by up to 60% compared to traditional methods.
  5. Water-Conscious Living: Fixing leaks, using water-saving appliances, and choosing local, low-water crops all help.


Concrete: The Silent Giant

Concrete is the second most-consumed material in the world after water. It’s in our homes, roads, bridges, schools — the foundation of the modern world. Every year, we produce over 4 billion tonnes of cement, the key ingredient in concrete. But the environmental toll is immense.

The Problem

  • Cement production alone accounts for around 8% of global CO₂ emissions.
  • Sand mining for concrete is destroying riverbeds, ecosystems, and coastlines.
  • Concrete-heavy urban design increases surface heat and disrupts natural water cycles.
  • Once poured, concrete is virtually impossible to recycle or repurpose in any meaningful way.

Solutions: Building Without (or With Less) Concrete

  1. Hempcrete: A biocomposite made of hemp shiv, lime, and water — lightweight, insulating, carbon-sequestering, and breathable.
  2. Compressed Earth Blocks (CEBs): Made from local soil with minimal cement or stabilizer, they offer durability with far less impact.
  3. Strawbale Construction: Highly insulating and renewable, strawbale homes are making a comeback in natural building circles.
  4. Timber & Bamboo: Responsibly sourced wood and engineered bamboo are strong, flexible, and far less carbon-intensive.
  5. Recycled Materials: Crushed glass, plastic waste, and even recycled concrete can be used in place of virgin materials.
  6. Modular Design: Building for disassembly ensures materials can be reused rather than wasted at the end of a structure’s life.


A Future Built on Balance

The question is not how to stop using water or concrete entirely — it’s how to reimagine our use of them. With awareness, innovation, and a willingness to return to nature-inspired solutions, we can live in harmony with the Earth, rather than in opposition to it.

The choice is ours. Every drop and every brick can either contribute to destruction or help shape a better world.
