Janet Smith wrote that "the waste protesters are just a bunch of Nimbys" (Letters, July 29) but, as governors of Downs Infant School, we have a duty of care to our children and staff.

Our issue is nothing to do with house prices but is about safeguarding people's health and wellbeing - and that alone.

Ms Smith wrote of the huge lorries trundling past the schools in Portslade. An extremely busy main road, with high levels of traffic, is already situated to the west of Downs Infant School.

The site of the proposed waste transfer station is to the east, adjacent to an area of particularly poor air quality caused by traffic pollution.

We are saying, enough is enough. The Hollingdean site has long been used for industrial practices and our school has not objected to these before.

It is the sheer scale of this waste proposal which we find wholly unacceptable.

I suspect that, should Ms Smith talk to the governors of Portslade schools, they would fully comprehend our vociferous opposition to this proposal.

-Rachel Attwell, chair of governors, Downs Infant School, Brighton
