P1: One of the classic science-fiction treatments of the end of civilization was The Death of Grass, by John Christopher, in which a mysterious sickness struck down all the grass on which most of the world's agriculture is bad, from rice to wheat. (1) In the end, politics among the survivors of dia, war and famine were reduced to bitter
atricidal (手足相残)struggle over a defensible potato patch. Like mos
f the so-called "comfortable disaster" novels, this could be criticized for
timism. Depressing as a future of famine and the war of all against all might em, the conquences were largely limited to humans.
P2: However, the threatened extinction of inct populations around the world rais the
prospect of a much less general disaster, which would involve plants, birds, fish, small mammals, and everything el depending on incts. That's just the start. Other species, and wc ourlves, dependon the animals and plants that need incts. When they go, we go. (2)
This is not just a greater disaster. It's a much more reasonable one. The
仲大军most recent has concluded that inct biomass is decreasing around the world at a rate of 2.5% a year. At that rate, half the incts in the world will be gone in 50 years' time, and all of them in a century-though no one will be keeping track of centuries then.
P3: The chief driver of this disaster is unchecked human greed. In spite of our individual and even collective cleverness, 3A we behave as a species with as little foresight as a colony of nematode （线虫）worms that will consume everything that it can reach until all is gone and it dies off naturally. The challenge of behaving more intelligently than creatures that have no brain at all will not be easy. 3B But unlike the nematodes, we know what to do. The UN convention on biodiversity was signed in 1992 alongside the co
nvention on climate change. Giving it the strength to hold back our appetites is now urgent. Biodiversity is not an optional extra. It is the web that holds all life, including human life.

It appears that
most of the damage is being done in the developed world by farming practices. The u of giant fields, lack of shelter for incts of any sort at all, whether they are harmful to human interests or not, and where the plants are drenched in long-lasting pesticides, is fatal for uncounted billions of incts. 3C The effects of this kind of farming reach beyond the fields immediately affected, too. There has been a huge loss of aquatic inct species from the rivers into which the products of industrial agriculture are flushed by rain. 3D Even in German nature rerves, which are by definition protected from the u of pesticides, there have been steep falls in inct populations becau so many of the most widely ud ones are persistent and prevent breeding.
