Why Human Beings Need Plants
Plants are all around us—in our gardens, parks, forests, and even in pots at home. They are green, beautiful, and very important for human beings. For Grade IV students like you, learning about plants is exciting because they help us live, grow, and stay healthy. In India, where we see plants like tulsi, neem, and mango trees, plants are a big part of our lives. Let’s explore why human beings need plants in a simple and fun way!
1. Plants Give Us Oxygen to Breathe
Plants are like nature’s air machines. They make oxygen, which is the air we breathe to stay alive. During a process called photosynthesis, plants use sunlight, water, and carbon dioxide to make their food and release oxygen. Without plants, there would be no oxygen for us to breathe!
Example: When you play in a park full of trees, you feel fresh because the trees are giving you clean oxygen.
In India: Trees like banyan and peepal are common in villages and cities. They give us oxygen and make the air cooler.
2. Plants Provide Food
Almost all the food we eat comes from plants, either directly or indirectly. Fruits, vegetables, grains, and spices all come from plants. Even animals we get food from, like cows, eat plants like grass.
Example: Think of your favorite meal, like rice, dal, and mangoes. Rice comes from the rice plant, dal from pulses, and mangoes from mango trees.
In India: We love foods like chapati (made from wheat), potatoes, and bananas, all from plants. Spices like turmeric and coriander also come from plants!
3. Plants Give Us Medicines
Many medicines we use to feel better when we’re sick come from plants. In India, plants have been used for healing for thousands of years in Ayurveda, a traditional way of medicine.
Example: The tulsi plant is often grown in Indian homes. Drinking tulsi tea can help with coughs and colds.
In India: The neem tree is called a “village pharmacy” because its leaves, bark, and seeds are used to treat skin problems and fevers.
4. Plants Keep the Environment Clean
Plants help clean the air by taking in harmful gases like carbon dioxide and trapping dust. They also stop soil from washing away during rains, which keeps our land strong.
Example: Trees along roads in your town reduce dust and pollution, making it easier to breathe.
In India: In cities like Delhi, where pollution can be high, planting more trees helps clean the air. Mangroves in coastal areas like the Sundarbans protect land from erosion.
5. Plants Give Us Shelter and Materials
Plants provide materials we use to build homes, make clothes, and create things we need every day. Wood from trees is used for furniture, and cotton from plants is used for clothes.
Example: The chair you sit on in class might be made from wood, and your school uniform might be made from cotton.
In India: Bamboo is used to build houses in villages, and jute from plants is used to make bags and ropes.
6. Plants Make Our World Beautiful
Plants make our surroundings colorful and happy. Flowers like marigolds and roses decorate our homes, schools, and festivals. Gardens and parks with plants are fun places to play and relax.
Example: During festivals like Diwali or Onam, we use flowers for rangoli and decorations.
In India: Jasmine and lotus flowers are loved for their beauty and are used in puja ceremonies.
7. Plants Help Animals and Insects
Plants provide food and homes for animals, birds, and insects. Bees make honey from flowers, and birds build nests in trees. If plants disappear, animals would suffer, and so would we.
Example: When you see butterflies in a garden, they’re visiting flowers for nectar.
In India: Peacocks and parrots depend on trees like mango and fig for food and shelter.
Why Should Grade IV Students Care?
As a Grade IV student, you see plants every day—at home, in school, or on the way to the market. Plants are our friends because they:
Help us breathe and stay healthy.
Give us yummy food and medicines.
Make our world clean, beautiful, and safe.

In India, we have a special connection with plants. We worship trees like peepal and tulsi, and we celebrate festivals with flowers and leaves. By learning about plants, you can help protect them by planting trees, watering plants, and not plucking leaves unnecessarily.
