Analysis of a Paragraph in my Proposal

My ah ha moment is the need to write distinct paragraphs with a clear issue, point and discussion

I have no questions but would like to inform you - Adam, that I revised my proposal a bit and have re-emailed it to geology230@gmail.com Thanks

Here is the first paragraph in my proposal.

Historically, sinkholes in North American karstic topography, have both endangered human life and caused significant damage to property. In 2004, the state of Florida alone can claim paying over 25 million dollars in property damage claims from sinkhole subsidence. Sinkholes are geologic features formed by the movement of rock or sediment into voids created by the dissolution of water-soluble rock (Dobecki, 2006). Such voids appear sporadically throughout North American karst, as both natural processes and human activity contribute to such dissolution. This paper proposes to investigate these sinkhole formations and how scientists can quickly detect and remediate these danger zones for the regional benefit to society.
