With 200 offices all around the world, GHD employs 8500 people and has 90 years of experience. It provides engineering, architecture, environmental and construction services to private and public sector clients.

In that context, my Year 11 students learned that the Australian government checks the state of the national forests very precisely every year by collecting and analysing data of native plants, trees, soils and animals.

Marois spoke about contaminated soils, a big problem in Australia and asbestos. (l’amiante in French).

Marois presented also different environmental projects done by GHD, including wind farm projects, contamination assessment of a soil, improvement of water quality, mosquito monitoring, collecting plants and analysing data, assessing the level of noise or the quality of air and developing water networks for remote communities to improve their quality of life.

My students discovered that the new trend at the moment is solar energy with photovoltaic panels. And yes, according to Marois, global warming is not a myth.

Precise measures about water, air and soil show that the temperature is rising and that corals are getting whiter. Finally, Marois shared his philosophy with my students:

“The forests are yours tomorrow, so you have to take care[of] it. 40 per cent of energy worldwide is used for heating and air conditioning. We can reduce our energy consumption because[to] consume less means [to] pollute less”.

“Mais vous, que faites-vous pour l’environnement?”asked one of my students?

“I buy quality products and I keep them longer,” answered Arnaud.

“I don’t change my phone every year, I use fans instead of air conditioning at home, and avoid it while in my car. I also look at the origin of the products and give preference to Australian ones. Finally, I look at the ingredients to make sure they hare not harmful for my health”.

In a word, "l’environnement est partout", he said. (Environment is everywhere).

His final message was about the necessity to speak several languages because one language, even English, is not enough in our global world. He speaks himself French, English, Russian and Spanish.

“You must travel and get used to work with different communities. Travelling allows you to understand other cultures and accept them, be more open-minded. The new skill of this century will be flexibility: plusieurs langues, plusieurs pays, plusieurs clients. (several languages, several countries, several clients),” he explains.
