Environment, sustainability, and nature conservation talks
I have been monitoring and speaking on conservation, nature and sustainability topics for over 20 years. Through my travels, research trips, and my university teaching, I can illuminate and clarify important environmental issues from a real world standpoint. Click on a talk to find out more.
Where our energy comes from is a topic of vital importance for security, cost and environmental reasons. this entertaining and visually appealing talk looks at our energy options and evaluates their feasibility. It also looks at the political issues, and what are the devastating consequences when societies have their energy curtailed. Finally, it explores the human rights and foreign policy considerations that devolve from how we choose to source our energy. The talk ethically examine the choices ahead of us and the impacts on societies around the world.
Our lifestyles are having profound impacts on the Earth's ecosystems. How much of nature are we prepared to sacrifice to sustain our lifestyles, and does it matter? Are we living sustainably? Is it possible for everyone in the world to enjoy a decent material quality of life without losing the simple pleasure and wellbeing that having nature in our lives brings? What are the conservation challenges? I explore how 'progress' is measured and what environmental costs we are prepared to pay to maintain current living standards. This is a thought provoking and enlightening talk for a general audience.
Climate is changing, but then it's always changed. Why is climate change such a hot topic now? Is it important?
What is global warming? Should we take it seriously? How can we understand it when the science seems so impenetrable?
This talk aims to clarify the issues and techniques used in this fascinating detective story as science tries to tackle perhaps its biggest challenge: understanding the planet and the consequences of anthropogenic climate change.
In this talk I examine the impossibility of finding anywhere on Earth that has not been affected by mankind's activity, how we reconcile that with notions of wilderness, how we value nature, and the necessary redefining of what is now 'natural'.
Antarctic environmental science has loomed large in my professional life. Ozone depletion, climate change and plate tectonics have all given up secrets to scientists studying in one of the harshest environments in the world. Here I explore Antarctica with world class environmental scientists and look at why it is so important to our understanding of the planet and what the future might hold.
