Staff members at the Brooklyn Botanical Garden are launching a campaign called “Fight for Sunlight” in an effort to stop a proposed complex from being built nearby.

Staff members say a proposed high-rise development on Franklin Avenue would cast shadows on the garden's conservatories, greenhouses and nurseries, blocking much needed sunlight for the plants.

The proposed plan includes a mixed-use development being built near the garden, including two 39-story towers.

Garden staff say if the towers are built, the plants would lose up to four hours of sunlight a day, threatening the growth of the plants.

Staff members are using the campaign as a way to take action against the proposed development, and using it as an opportunity to educate the public on the issue.

They say they hope that bringing awareness of the issue, developers will consider the impact of the project.
