Conflicting Views On Aerial Spraying
Aerial spraying has been controversial since the 1960s, due to environmental concerns about pesticide drift (raised for example by Rachel Carson's book Silent Spring). It is now often subject to restrictions, for example spraying pesticide is generally banned in Sweden, although exceptions can be made such as for an area plagued by mosquitoes during summer. Even the spread of fertilizer has raised concerns, for example in New Zealand fertilizer entering streams has been found to disproportionately promoted growth of species more able to exploit the increased nutrients, so leading to restrictions on topdressing near waterways. Even putting out forest fires has been criticized in the U.S.A. as preventing natural consumption of flammable material, and increasing long term risk.

Famous quotes containing the words conflicting, views, aerial and/or spraying:
“Certainly for us of the modern world, with its conflicting claims, its entangled interests, distracted by so many sorrows, so many preoccupations, so bewildering an experience, the problem of unity with ourselves in blitheness and repose, is far harder than it was for the Greek within the simple terms of antique life. Yet, not less than ever, the intellect demands completeness, centrality.”
—Walter Pater (18391894)
“The absolute things, the last things, the overlapping things, are the truly philosophic concerns; all superior minds feel seriously about them, and the mind with the shortest views is simply the mind of the more shallow man.”
—William James (18421910)
“Every year lays more earth upon us, which weighs us down from aerial regions, till we go under the earth at last.”

“[Ognev] recalled endless, heated, purely Russian arguments, when the wranglers, spraying spittle and banging their fists on the table, fail to understand yet interrupt one another, themselves not even noticing it, contradict themselves with every phrase, change the subject, then, having argued for two or three hours, begin to laugh.”
—Anton Pavlovich Chekhov (18601904)
