Population Increase Affects Both Ecosystems and the Food Chain

An ecosystem is generally understood to be the combination of biological, physical and chemical factors that make up a particular locality and can be anything from a pond to a rainforest to a desert.

There are two components to an ecosystem, the abiotic components, such as sunlight, temperature, temperature, water or moisture, and soil chemistry, and the biotic, the living organisms from plants to insects to animals to humans, all of which interact together.

Ecology is a way of describing how the different component parts of an ecosystem interact and function whether it is the amount of energy produced by photosynthesis or how energy and materials flow along the food chain.

Energy transfers in a continuous cycle from growth to decay and back again throughout an ecosystem, and the rate at which it does so depends on a number of factors. However, energy transfer through the food chain becomes more inefficient as it progresses from what is called the primary producer (plant) level through the herbivorous primary consumer level and on to the carnivore level.

All of this is fine when the various elements of an ecosystem are in balance and working well together, but it doesn’t take much to destabilize it.

Climatic changes, such as prolonged drought or rainfall, can affect the balance or a change in the animal population, so there are probably many predators that can be supported in a given area.

Human activity has arguably one of the most important impacts on an ecosystem in a variety of ways. Once an area of ​​land is used for a specific purpose, such as agriculture, it can lead to several problems.

Once populations begin to cluster into communities and the economic system becomes increasingly dependent on urbanized life, along with greater scientific understanding of public health and medicine, death rates fall and populations begin to grow.

This puts more pressure on those who work the land to produce food to become more efficient and again innovations such as agricultural machinery – and eventually methods such as chemical and mineral-based pesticides and fertilizers must be used to control pests and crop diseases and to increase yield. from the ground.

Meanwhile, increasingly new and “efficient” farming methods create a hostile environment for wildlife, including their natural predators and pests, perhaps because the areas where they live and shelter such as fences have been removed to allow for larger agricultural vehicles to operate efficiently.

Intensive farming also means that there is no time for the soil to recover and restore nutrients naturally through the cycle of growth and decay. The human population continues to grow as life expectancy and birth rates increase and add stress on the ecosystem.

It is the result of many centuries of such “improvements” in food production and survival and population growth that has led to current concerns about food shortages and the need for farmers to increase food production.

But it has also become clear that increasing food production must be done sustainably as the flaws of previous farming methods have become apparent, not least because of the residual effects of some of the older generation fertilizers on human health, but also because of the damage caused to the ecosystems in which they are used.

Hence the current emphasis on sustainable farming methods and integrated pest management, but if the world is to support a population expected to reach more than 9 billion by 2050 without further damage to the world’s ecosystems, something must change. .

Biopesticide developers have been at the forefront of finding solutions, researching more natural (aka low-chemical) agricultural products—using natural ingredients to create biopesticides and yield enhancers that will protect the soil and help grow crops. yields from the limited amount of land available while minimizing waste caused by crops lost to disease and predators.

It is the work of such innovators that will hold the key to ensuring sufficient food and protecting the earth and its vulnerable ecosystems for the future.
