I'm not a huge fan of Las Vegas. It's a fun place to go to play a bit of poker but it's so man-made. And being quite environmentally conscious, I couldn't believe the amount of neon lighting in the city.
Public figures talk and act as if environmental change will be linear and gradual. But the Earth's systems are highly complex, and complex systems do not respond to pressure in linear ways.
I became an environmentalist because I love the living world, but I spend much of my life thinking about electricity, industrial processes and civil engineering.
Economic growth is the aggregate effect of the quest to accumulate capital and extract profit. Capitalism collapses without growth, yet perpetual growth on a finite planet leads inexorably to environmental calamity.
Immense wealth translates automatically into immense environmental impacts, regardless of the intentions of those who possess it.
Like every other viable environmental policy, the search for clean energy begins at home.
Environmental degradation has one cause above all others: the propensity of human beings to take the benefit and leave the costs to someone else, preferably someone far away in space or time, whose protests can be safely ignored.
My main argument is that environmental destruction comes when people externalise their costs and pass them on to future generations. That is obviously something that large enterprises do and they become large by doing it.
We don't value food in Britain, so therefore the cheaper it is the better it is. We all eat far too much, we all pay far too little for our food. We have environmental problems, we have health problems, we have food transport problems.
Californians want to have clean air, clean water - not like the Trump Administration is trying to do with its rollback of environmental regulations, like the reversal of the Clean Power Plan.
It is undeniable that the looming environmental crisis is partly the consequence of population growth.
Genetic modification is a very powerful tool. But like any powerful tool, when using it, you have to take into account the environmental impact, the food safety aspects and so on. There must be a strong regulatory mechanism.
