The new medicinal herb and aroma garden at Stamford Hospital's Tully Health Center

In 2010, Ganga Duleep, master gardener and preceptor for UCONN, spotted an open space outside of Tully health Center at Stamford Hospital in Stamford, CT, while she was checking up on Thai basil plants. She saw an empty grass, and thought, why not plant a medical garden for better use. The idea of the garden was to naturally heal and cure illness. The garden has a variety of different plants each with different uses. Chinese rhubarb, curry leaf, lemongrass, aloe, and cinnamon, are some of the plants in the garden. In May 2011,

Duleep has shown a great example of human uses of plants, by planting a healing garden she has used plants for medicine.

1.3 Clothing

Most of our clothing come from plants. Throughout history, clothing has either been made of plant or animal fibres. Some of the earliest examples of clothing are made of wool or linen.

Linen is two to three times stronger than cotton and also cooler and lighter. Hemp fabric is made from the stems of the Cannabis sativa plant. The fabric is strong, durable and resistant to ultraviolet light and mold.[7]

Shelter is one of the elements of survival, along with food and water. Shelter offers people safety and security. Often a person’s shelter is a reflection of their personal habitat. In many part of the world, wood is used a lot for shelter. Wood is used to construct modern homes. Furniture is commonly composed of wood and cloth made from plant fibers. Walls are often covered with paper, and some paints and varnishes are derived from plant extracts. Bamboo can also be used to make shelter, because of its strong material.[8] Plants a re also used to make paper, with is very important today. Papyrus, a grasslike plant, was used more than four thousand years ago in the first endeavor, by Egyptians, to make paper. It is from this plant that paper has derived its name.[9]

1.5 Fossil Fuels

Fossil fuels have been provided by plants and animals that have died a long time ago. These plants are the origin of coal, oil, and gas that can be used for heating and cooking purposes. Humans have been using fossil fuels everywhere and in many different ways. Fossil fuels cover many types of fuels that are now used to power cars, homes, and even entire cities. The most common fuel is coal; it has been used at the dawn of the industrial revolution, but has over time changed its application as a source of energy. At first it was

used to steam engines of locomotives, later it became the main fuel source of power plants. Today it has still been the most used source of electric power. Gasoline plays an important role in our economy, because of its ability to power most today's automobiles and vehicles.[10] The demand for gas is increasing as more and more countries develop a market for cars and trucks. Most of the world supply of gasoline is in the Middle East, which is not very good for western countries because of their poor relations. The oldest form of fuel is wood, which is burned to create heat for warmth and for cooking.[11] Although fossil fuels have a great role in human lives, it is also a treat to the environment because of the pollution that is produced by the factories.
