What is Environment?
An Environment can be defined as everything that is around us, which includes both living and nonliving things. The environment plays an important role in the existence of life.
Importance of the Ecosystem
An ecosystem is defined as the biological community of interacting organisms and their physical environment. It is mainly composed of both living and nonliving parts of the environment.
Plants, Animals, birds, microbes, humans and all other living species are all living parts of the environment and are also called the biotic components of the ecosystem. Sun, wind, rain, water, soil, air, food are all nonliving parts of the environment and are also called the abiotic components of the ecosystem.
Food chain and food webs, both play an important role in maintaining an equal balance of the ecosystem.
Impacts of Human activities on the Environment
Humans impact the environment in several ways. We all are dependent on more luxuries but not worried about its effects on the environment. With the increased population, several human activities and more demand towards the extravagances has led to the more destruction of the environment.
The most significant environmental issues include discharging of wastes into fresh and clean water bodies, polluting fresh air by burning fossil fuels for energy, throwing wastes and dumping garbages, deforestation, and lot more. All these Humanity’s effects on the global environment have led to global warming, emissions of greenhouse gas, depletion of natural resources, contribution to global climate change, and depletion of the ozone layer.
