More than 500,000 birds — a third of the swallow population — have vanished from the countryside since 1970. Some conservationists blame bird-proof farm buildings while others suggest the widespread sse of eco-friendly farm chemicals. ——————————————————————————————————1/3—— Environment news 461 Club 440 440 BEAVERS RETURN TO BLIGHTY p465 Global News Action Eco Scene

But these insects are being driven away by new natural pesticides ssed on cattle. While the insecticides are said to be harmless to livestock and man, the British Trust for Ornithology says they could indirectly harm birds. "Birds, bats and badgers forage at cow- pats and the lack of fauna at them might be very damaging," the BOT says. ——————————————————————————————————2/3—— Education 660 Grooves 620 IT'S YOUR LIFE p480 Global News Action Eco Scene

But manufacturer MSD Ag Vet strongly denies this pesticide has any harmful effects on wildlife. Only young cattle are treated, it says leaving enough untreated pats for the insects to feed on. ——————————————————————————————————3/3—— Keep up with the green events 464 British Trust for Ornithology 01842 750050 Global News Action Eco Scene
