The amount of waste produced in the United States each year is truly staggering, reaching a whopping 268 million tons. This waste has far-reaching social and environmental consequences, including contributing to greenhouse gas emissions, endangering wildlife, disrupting natural ecosystems, and posing risks to human health. Only 9% of all plastic waste produced has been recycled, leaving 91% to leech into our environment. As the tech industry booms, electronic waste increases, and the United States wastes more food than any other country.

2023 marks the 30th Anniversary of the Santa Clara Valley Open Space Authority. The agency was founded in 1993 as a public, independent special district – envisioned by dedicated local citizens and enacted by the California State Legislature – with the mission of forever protecting natural and agricultural lands and connecting people to nature. The Open Space Authority is funded by a voter-approved benefit assessment and parcel tax (Measures Q and T) and grants. The agency’s jurisdiction is 1,000 square miles and includes the cities of Campbell, Milpitas, San José, Santa Clara, Morgan Hill, and the unincorporated areas of Santa Clara County.
