Solve the following python programming problem given the following code:
@ click.command (short_help = 'Write bounding boxes to stdout as GeoJSON.') 
@ click.argument ('INPUT', nargs = (- 1), type = click.Path (), required = True) 
@ precision_opt 
@ indent_opt 
@ compact_opt 
@ projection_geographic_opt 
@ projection_projected_opt 
@ projection_mercator_opt 
@ click.option ('--dst-crs', default = '', metavar = 'EPSG:NNNN', callback = to_lower, help = 'Output in specified coordinates.') 
@ sequence_opt 
@ use_rs_opt 
@ geojson_type_collection_opt (True) 
@ geojson_type_feature_opt (False) 
@ geojson_type_bbox_opt (False) 
@ click.pass_context 
def bounds(ctx, input, precision, indent, compact, projection, dst_crs, sequence, use_rs, geojson_type) : 
    'Write bounding boxes to stdout as GeoJSON for use with, e.g.,
    geojsonio

      $ rio bounds *.tif | geojsonio

    If a destination crs is passed via dst_crs, it takes precedence over
    the projection parameter.

        dump_kwds ['separators'] = (',', ':')

    Fix the buggy line: write_features (ctx, Collection (env), sequence = sequence, geojson_type = geojson_type, use_rs = use_rs, ** dump_kwds)
