My commitment: Helping cities coexist with nature without destroying it

For the first time in history, the majority of people are living in urban areas. To avoid climate catastrophe, cities must invest in the infrastructure of the future—renewable energy, mass and personal transit, and advanced sewage and waste management. We must get away from using finite resources and instead close the loop to turn waste into sustainability.

My work explores public policy and city planning solutions to promoting sustainable lifestyles. From the transportation we take to our energy sources to how we manage our food waste, there are concrete solutions to making effective changes now that will ensure our survival in the future.
