Across the US Midwest, in Michigan, Ohio, Illinois, and Indiana, forests are dying out. Once abundant in varieties, they now look like they were defeated by forest fire yesterday. The cause of this shocked the experts. A small insect, an emerald ash borer, has caused damage that can be compared to a natural catastrophe. So, what is an emerald ash borer impact onecosystem?
With increasing population, environmental pollution has increased manifold in the last couple of decades. This affects human beings as well as other living things. But most vulnerable are infants and children. Environmental health risks for infants are more than adults because:
Rain forests are those forests which experience a high amount of rainfall. They are important ecosystems which have a sustainable model for the biotin species in them. Nearly 40-70% of all species originate in the rain forests. Tropical rain forests are a natural treasure with more than 25% of herbal medicines found here. Rain forests are characterized by dense vegetation and through photosynthesis, they contribute to more than 28% of the total oxygen movement on earth. Today, with so much deforestation, only about 6% of the earth’s surface is covered with rain forests. However, they are inhabited by more than half of the known species of animals and plants in the world.
Before we start understanding wildfire impact on ecosystems, let’s understand “wildfire.” Wildfire is an uncontrolled movement of fire inside forests and represents one of the most destructive natural forces. Annually, about 50 000 forest fires are registered in the world which takes an average of about 400 000 ha of forest.
Water pollution is the contamination of water bodies like lake, sea, river etc. The pollutants discharged into the waterbodies enter without proper treatment. The sewage and the waste can produce algae content in the water which is massively destructive for various water bodies. The polluted water contains highly toxic substances which are harmful to a human who depends on the sources of the water bodies as well as for the aquatic life. So we would now focus on the causes as well as the effects of water pollution on ecosystems.
Billions of people depend on fish for their food requirement. Also, there are a lot of people for whom fishing is a source of income. With the growing population, the demand for fish is also going up. This means that on a daily basis, fish are being captured from their marine habitats. Fishing is already a multimillion-dollar industry and a thriving business for many. So, we have technology helping men dive deeper and catch more fish. But are we ‘Overfishing’? If yes, then what are the effects of overfishing?
An ecosystem is identified by a set of different characteristics that connect the animal kingdom with the plant kingdom, a specific environment in which each entity needs the other to coexist. That is to say, its life process is linked directly, and in an evolutionary way,to the living organisms that make it a home.
The Ecosystem can be thought of as a single unit containing living things and non-living things, and the living things interact with the non-living things and also with the environment, working as a system. The Ecosystem and its Components are thought of as entities in a limited, defined space – for e.g., a forest or an ocean. However, according to some scientists and ecologists, the entire planet is an ecosystem. Ecosystems are controlled by both internal and external factors. The external factors such as the climatic conditions define how the ecosystem works, but do not get affected by the ecosystem itself.
In order to have an in-depth understanding of an ecosystem, you should first learn your basics. Though you have learnt it like several times in your lower grades, we will still start from the scratch, for the benefit of the people who slept in their science classes. What is an ecosystem? An ecosystem is a […]
Human beings form the highest point of the food chain and the ecosystem. While almost all the other components of the ecosystem are influenced by the ecosystem, human beings are the ones that influence and gain control over the ecosystem, at least for the most part of it. This is the reason why people can […]
