Forest helps in cleaning the environment by absorbing toxic gases like carbon. They help to prevent soil erosion and uphold the fertility of the soil. They help to establish oxygen and carbon balance in nature, and hence, the forest is essential for maintaining an ecological balance. Healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. They provide raw materials and resources for medicines and other purposes. They are at the foundation of all civilization and sustain our economies.

A balanced ecosystem signifies a habitat which is sustainable. It consists of animals, plants, microorganisms and more which depend on each other and their surroundings. These ecosystems exhibit resourceful energy and material cycling. It also displays interconnectedness amid primary producers and predators. It provides habitat to wild plants and animals. It promotes various food chains and food webs. It controls essential ecological processes and promotes lives and involved in the recycling of nutrients between biotic and abiotic components. Environmental balance is maintained in the following ways: Through continuous operation of various natural cycles such as the water cycle, carbon cycle, oxygen cycle and nitrogen cycle. It is also maintained due to the existence of various food chains in the ecosystem. Half of the planet's rainforests have already disappeared. The Amazon is still the most extensive rainforest on earth, but a disastrously large part of it is now in danger of disappearing for good. Our goal is to prevent that disaster. Ecological balance is a state of dynamic equilibrium within a community of organisms in which genetic, species, and ecosystem diversity remain relatively stable, subject to gradual changes through natural succession. The environment regulates various natural cycles that happen daily. These cycles help in maintaining the natural balance between living things and the environment. Disturbance of these things can ultimately affect the life cycle of humans and other living beings. Since forests contain a large number of plants and trees, they help in maintaining the balance between oxygen and carbon dioxide in the atmosphere. Forests provide shelter to a wide range of animals. If the trees are destroyed, these animals also die as they do not have their natural habitat. This destruction makes many of the endangered species of plants and animals extinct. Forests play a role in the carbon cycle by absorbing carbon dioxide from animals.
This is just jargon. Terms balanced, healthy, etc. have no technical definitions. They are mantras of environmentalism that presumes to know the "perfect" state.
