Good use of while read. You can redirect the entire loop instead of reopening download.txt 1000 times though:
Code:
while read line
do
        wget ...
done > download.txt

wget also has some features which make a loop unnecessary though Smilie

wget is able to read a list of files with -i. The -nv option is also useful, to make it still print completed files without printing all the complicated junk wget usually does.

Code:
wget -nv -i urls_list.dat > download.txt

This should be much faster than calling wget 1000 times since it is able to re-use the same connection if it's connecting to the same site. Concurrency may not be necessary ( and may not be desirable in many cases -- how fast is your connection? ) but if it is, I'd split the list into parts and use wget -i on those parts.

NAME
lwp-download - Fetch large files from the web SYNOPSIS
lwp-download [-a] [-s] <url> [<local path>] DESCRIPTION
The lwp-download program will save the file at url to a local file. If local path is not specified, then the current directory is assumed. If local path is a directory, then the last segment of the path of the url is appended to form a local filename. If the url path ends with slash the name "index" is used. With the -s option pick up the last segment of the filename from server provided sources like the Content- Disposition header or any redirect URLs. A file extension to match the server reported Content-Type might also be appended. If a file with the produced filename already exists, then lwp-download will prompt before it overwrites and will fail if its standard input is not a terminal. This form of invocation will also fail is no acceptable filename can be derived from the sources mentioned above. If local path is not a directory, then it is simply used as the path to save into. If the file already exists it's overwritten. The lwp-download program is implemented using the libwww-perl library. It is better suited to down load big files than the lwp-request program because it does not store the file in memory. Another benefit is that it will keep you updated about its progress and that you don't have much options to worry about. Use the "-a" option to save the file in text (ascii) mode. Might make a difference on dosish systems. EXAMPLE
