回答下列问题：

    Living among trees, plants and flowers can fill your life with beauty. And if you are a woman, it can also help you live longer. Researchers found that women who live in homes surrounded by plants appear to have lower death rates than women who live in areas with fewer plants.

    Researchers at Harvard University's T.H. Chan School of Public Health reported the finding. They looked at the information from one of the largest and oldest investigations of the women's health: the Nurse's Health Study. It began 40 years ago. It now has information on nearly 200,000 women.

    For the new study, the team looked at the death rates of more than 100,000 women between the years 2000 and 2008. Then the researchers compared the death rates of these women to the plants around their homes. The researchers also considered other things, such as the age of the women, money they earn and race. They also looked at whether or not the women smoked.

    The study found that the death rate among women who lived in the greenest spaces was 12% lower than those from the least green areas. The researchers were surprised to find such a strong connection between high vegetation levels and low death rates.

    The study suggested that living among trees, flowers and other plants lowered levels of depression. Researchers said women in greener areas spent more time with other people and exercised more. It is common knowledge that plants can help the environment in many ways. The new finding also suggested ways to the government and the city planners to grow even healthier living areas.
