The companies tackling today’s environmental challenges


The first Earth Day was in 1970, and today, we must rise to meet these dual crises again as Earth Day marks 50 years.


The theme this year is ‘climate action’. The enormous challenge — but also the vast opportunities — of action on climate change have distinguished the issue as the most pressing topic for the 50th anniversary.


Climate change represents the biggest challenge to the future of humanity and the life-support systems that make our world habitable.


On April 22, 1970, 20 million Americans — 10% of the U.S. population at the time — took to the streets, college campuses and hundreds of cities to protest environmental ignorance and demand a new way forward for our planet.


The first Earth Day is credited with launching the modern environmental movement and is now recognized as the planet’s largest civic event. The first Earth Day, in 1970 launched a wave of action. The passage of landmark environmental laws in the United States. The Clean Air, Clean Water and Endangered Species Acts were created in response to the first Earth Day in 1970, as well as the creation of the Environmental Protection Agency (EPA). Many countries soon adopted similar laws.


Earth Day continues to hold major international significance: In 2016, the United Nations chose Earth Day as the day when the historic Paris Agreement on climate change was signed into force.


Here’s a quick introduction to some of the businesses within our collective who are tackling environmental challenges.


Meet the pioneers


Azotic Technologies

Working to reduce the global use of synthetic nitrogen fertiliser via their product N-Fix ®.


“Our team of scientists at BioCity are developing N-Fix®  as a platform technology based on enabling plant cells with the ability to fix their own nitrogen.   The bacteria are essentially giving nature a helping hand to transfer this naturally occurring bacteria derived from sugarcane into other crop species. The Company will commercialise a variety of technologies based on this platform.”
