Each year on April 22, one billion people across the globe take action to promote conservation and sustainability. Earth Day can drive a year — and even a lifetime — of energy, enthusiasm, and commitment to protect our planet.

This year’s Earth Day theme — “Invest in Our Planet” — aligns perfectly with what the San Diego County Water Authority and its 24 member agencies have done for decades. It points to the necessity of dedicating time and resources to ensuring a sustainable water supply for our community. And it speaks to the thoughtful investments we make in infrastructure and innovation that keep the water flowing while being mindful of the environment.

Investing in our planet can take many forms, and the challenges we face differ from community to community. One investment I encourage San Diegans to think about this Earth Day is landscape transformation. This is important because the biggest users of water at homes are our landscapes — perhaps as much as 70% of our water use, depending on where we live.
