Biodiversity is the greatest treasure we have... Its diminishment is to be prevented at all cost.
We advocate biodiversity for biodiversity's sake. It may take our extinction to set things straight.
Don't think in terms of comfort; think in terms of freedom. Don't think in terms of safety, think in terms of being more alive. And the only way to be more alive is to live dangerously, is to risk, is to go on an adventure. And the greatest adventure is not going to the moon - the greatest adventure is going to your own innermost core.
This is the rollcall of evolution happening in the space of a few generations, the greatest loss of living things that make up our biodiversity since the disappearance of the dinosaurs.
Whether we consciously realize it or not, the biodiversity with which we are most familiar, and the biodiversity with which we have most intimate historical, cultural and biological connections, is that associated with food plants.
The poverty fighters resent the climate-change folks; climate folks hold summits without reference to biodiversity; the food advocates resist the biodiversity protectors. They all need to go on safari together.
It is important to recognize that behind the razzmatazz of consumerism, we all remain dependent on basic natural resources - land, air, water and biodiversity - for every product and service. There can be no free lunch on the environment.
Instead of trying to understand agriculture in its own terms, acknowledge that agriculture ultimately comes out of nature. Right now agriculture is the No. 1 threat to biodiversity on the planet.
If we pollute the air, water and soil that keep us alive and well, and destroy the biodiversity that allows natural systems to function, no amount of money will save us.
It seems to me that the natural world is the greatest source of excitement; the greatest source of visual beauty; the greatest source of intellectual interest. It is the greatest source of so much in life that makes life worth living.
A World Cup in Brazil is the greatest event in which a footballer can play.
The thing that I think about most often is the loss of biodiversity. We talk about these food issues so often with concern to historically excluded communities, but I'm concerned with everyone having access to healthy foods. Consumers across the board are being robbed of biodiversity.
An agricultural landscape produces food but it also provides water, requires biodiversity to underpin soil function, pollination and other useful services, and also has value to society in terms of aesthetics and recreation
Apex predators are good for an environment in terms of biodiversity and trophic cascade - we have very few. But realistically, only a few areas could sustain free-roaming wolves in Britain, mostly in Scotland.
We have serious challenges regarding climate change, unsustainable use of natural resources, water scarcity, loss of biodiversity, forests and farmland. Not to mention the huge inequality still prevailing in several parts of the planet.
It is worth remembering that the time of greatest gain in terms of wisdom and inner strength is often that of greatest difficulty.
