Global warming is the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere. Climate change includes both global warming driven by human-induced emissions of greenhouse gases and the resulting large-scale shifts in weather patterns

Ecosystem Services: Examples

Without ecosystem services, life on Earth as we know it wouldn’t exist. There are four main categories of ecosystem services: Provisioning services refer to the products secured by ecosystems. These include: • Water • Food (including cattle and seafood) • Pharmaceuticals, biochemicals, and industrial products • Energy (sunlight, hydropower, biomass) Regulating services are the ecosystem services that allow the regulation of ecosystem processes such as: • Climate regulation (and carbon absorption and storage via the oceans, trees, soil) • Waste decomposition (one of the most essential microbial process happening in soil) • Crop pollination (performed by agents such as bees that contribute to the reproduction of flowering plants) • Water and air purification and regulation • Control of pests and diseases Supporting and habitat services refer to the ability of ecosystems to give habitat for migratory species and to support the viability of gene-pools.This is possible thanks to: • Primary reproduction • Nutrient and seed dispersal Cultural services are the benefits ecosystem services bring to humans. Examples of these are: • Inspiration for intellectual (creativity), cultural (entertainment) and spiritual (why) purposes – Remember how it feels good to seeing and hearing wild birds – Animals, plants and even the funghi kingdom serve as inspiration in theaters, movies… – Many people go to natural sites when they want to be alone or reflect about life • Recreational experiences such as outdoors activities or ecotourism

Why Is Preserving Ecosystems Important?

All other living beings, humans are dependant on natural ecosystem services to survive. We need it to get the food we eat, the water we drink and to transform raw materials into our everyday products. So in order to keep our living conditions, it’s truly important that we preserve natural ecosystems. For example, the agriculture that provides our food depends on the characteristics of a specific ecosystem. Cereals or vegetables grow only under certain conditions of temperature and humidity. They also need certain natural processes, such as pollination, to take place. If we change these characteristics too intensely, there is the risk that we aren’t able to produce what we produce today, or at least not in the same way. That’s why there are some agricultural techniques that understand and manage food production

How Do Natural Ecosystems Work?

Natural ecosystems are “balanced” systems. This means the interactions between the different organisms that make up the ecosystem contribute to a certain stability. For example, in grassland ecosystems, herbivores consume grass, but also feed the soil with their droppings, which allows the grass to grow back and allows some sort of balance. Still, this doesn’t mean an ecosystem, even a healthy one, is static. In reality, ecosystems are constantly evolving as they are based on dynamic processes that are constantly changing. For instance, biocenosis are living organisms that interact with their environment and constantly transform it. How? Because animals compact the soil, plants create humidity or regulate the temperature and bacteria help in the microscopic world by protecting all sorts of animals from diseases and helping in their digestion process. As well, an ecosystem also evolves due to external or unforeseen events. A climatic or natural phenomenon, for example, can lead to transformations in the environment. In this way, biocenosis the ecosystem’s living organisms to adapt to these new constraints, and change happens.

“An ecosystem is defined as a community of lifeforms in concurrence with non-living components, interacting with each other.” What is an Ecosystem? The ecosystem is the structural and functional unit of ecology where the living organisms interact with each other and the surrounding environment. In other words, an ecosystem is a chain of interaction between organisms and their environment. The term “Ecosystem” was first coined by A.G.Tansley, an English botanist, in 1935. Read on to explore the structure, components, types and functions of the ecosystem in the ecosystem notes provided below. An ecosystem can be as small as an oasis in a desert, or as big as an ocean, spanning thousands of miles. There are two types of ecosystem: Terrestrial Ecosystem Aquatic Ecosystem
