Protecting our ecosystem

Our ecosystems are finding hard to cope with the different pressures and abuse, are unable to adjust. Continue diminishing resources and destroying our environment will be very soon too late to recover.

Ecosystem is the basic unit of the field of the scientific study of our nature. According to this discipline, an ecosystem is a physically defined environment. This includes all of the living things like plants, animals and organisms in a given area, interacting with each other, and also with their non-living environments such as weather, earth, sun, soil, climate and atmosphere. The ecosystems are the basics of the biosphere and they determine the health of the whole earth and its system.

The term ecosystem was first used in 1935 by the British environmentalist Arthur Tansley in a publication. Tansley came up with the idea to draw attention to the importance of transferring materials between organisms and their environment.

Cause and links between human an ecosystem. Human activities and behaviours have had a negative impact on the climate and ecosystem. Climate change is largely known as ethnography, and stems from a variety of human activities. This means that climate change is having a direct and indirect impact on human society. Ecological degradation and loss of biodiversity are also caused by various human activities. Chemicals released into the environment have a variety of adverse environmental effects. Dyeing environmental effects from fish and wildlife to deforestation can cause long-term or short-term changes in the normal functioning of an ecosystem, resulting in economic, social and aesthetic damage. This can result in loss of ecosystem services in both quality and quantity.

The adverse effects on ecosystems; toxic pollutants and other phenomena can undermine the natural stability of an ecosystem and cause irreversible changes and serious damage. The effects of ecosystem destruction are as follows: (i) deterioration of forests, due to air pollution and acid deposition (ii) harm of fish production from copper pollution (iii) damage of timber growth, due to nutrient losses caused by mercury poisoning of microbes and soil insects (iv) harms numbers of species in ship channels subjected to repeated oil spills (v) harm of commercially valuable salmon and endangered species like bald eagle, osprey from forest (vi) Occurred flood due to the erosion of soil and lack of trees (vii) Increasing of the sea levels due to the melting of the glaciers, caused by Global Warming (vii) Water shortage (fresh drinking water) (viii) Food scarcity as the lands become barren and the oceans become fishless (ix) Damage of biodiversity as whole species of living things disappear due to deforestation (x) Pollution will eventually become unmanageable and affect our health (xi) Increasing temperatures too much for all living things on the planet.

Hence, each of these pollutant-caused damages has altered ecosystem processes and components and thus affected aesthetic and commercial value of an ecosystem.

The most important mitigation measures to reduce impacts on the ecosystem. Decrease or remove the use of household chemicals and pesticides that can hurt the environment. We may make our own cleaning solutions using distilled vinegar and baking soda. We may also purchase green cleaning products.

Need to recycle as much waste as we can and reduce the amount of waste we produce. We may create separate bins in our house and label them for glass, plastic, paper and aluminium, taking bins to nearest recycling centre.

Decreasing our waste is one of the best ways to help the environment. Use disposable paper towels, use reusable towels that can be washed rather than thrown away. Use reusable bags at the grocery store rather than using disposable plastic or paper bags.

Decrease carbon footprint. There are numerous ways to cut back on how much pollute resulting in a smaller carbon footprint. In our houses, we may turn hot water heater down a few degrees, wash dishes in the sink rather than the dishwasher, take showers rather than baths, turn down air conditioner or heater, and use energy efficient light bulbs and electronics. Choose transportation that pollutes less, such as public transportation.

Select locally grown and sustainably grown foods. Industrial food systems need to carry food all over the country and internationally, and food pesticides are needed to grow in large quantities. The method of transporting food pollutes the environment, but local foods do not need to be transported long distances. Organically grown food is also more sustainable, as it does not use pesticides that harm the ecosystem.

Likewise, negative environmental impacts should be avoided, for instance by re-siting the project to a more suitable location. If relocation is not feasible, science-strong measures should be deployed to minimize harms. If environmental impacts are inevitable, there should be appropriate compensation or adjustment.

Ecological resistance and resilience are important when we consider the effects of disturbances caused by human activity. If a problem is severe enough, it can change an ecosystem without a recovery point, pushing the ecosystem into an area where it is no longer resilient. The ignorance and disorder can lead to permanent change or damage to our ecosystem.
