World Environment Day in 2021
In 1972, the UN General Assembly designated 5 June as World Environment Day (WED). The first celebration, under the slogan “Only One Earth” took place in 1974. In the following years, World Environment Day has developed as a platform to raise awareness on the problems facing our environment such as air pollution, plastic pollution, illegal wildlife trade, sustainable consumption, sea-level increase, and food security, among others. Furthermore, World Environment Day helps drive change in consumption patterns and in national and international environmental policy.
World Environment Day 2021 Theme: Ecosystem Restoration
The theme of World Environment Day 2021 is Ecosystem Restoration. Ecosystem Restoration can happen by actively planting trees or by removing pressures on the ecosystem by protecting environment and reducing the increasing level of pollution.
Ecosystem Definition:
The simplest definition of an ecosystem is that it is a community or group of living organisms that live in and interact with each other in a specific environment.
For instance, tropical forests are ecosystems made up of living beings such as trees, plants, animals, insects and micro-organisms that are in constant interaction between themselves and that are affected by other physical (sun, temperature) or chemical (oxygen or nutrients) components.
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.
It’s also curious that although an ecosystem is always looking for stability, the ecosystem never perfectly succeeds at it. The various natural imbalances tend to offset each other permanently. Some ecosystems evolve very slowly while others can transform very quickly. Sometimes, in extreme cases, they can even disappear.
Ecosystems And Human Activities
We’ve managed to control fire, practice agriculture, and build transportation vehicles. We’ve built factories, dams, solar panels and we’re constantly finding new ways of exploring space. Still, the human race’s thirst to use, modify and transform natural ecosystems seems endless. For instance, when we transform a plain to grow cereal fields, we’re significantly modifying that local ecosystem. Sometimes, we even end up completely changing it from its original foundations.
Today, human activities have such an impact on ecosystems that we now speak of the Anthropocene timeline. This is a period that defines the significant human impact of human activities on the Earth’s atmospheric, biosphere, geologic and hydro logic systems. This period in time also considers changes happening due to climate change events, which is also mainly caused by human activities. We can see all these changes everywhere. When trees are taken down in the Amazonian forest, the ecosystems change as species struggle to survive and the local humidity and the climate both change. As well, building a dam also changes the distribution of water and affects the species living along the river’s course.
Why Is Preserving Ecosystems Important?
Like
all other living beings, humans are dependent 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
Slogans on World Environment Day
As the lock down happened last year, all of us witnessed the mother earth rejuvenating back to greener lands and cleaner skies. You might have heard chirping birds on your balcony and pleasant weather throughout the summer and winter season. While the human world is still striving to fight a dangerous virus, our environment took the opportunity to renew itself and heal from the wounds we left on it. World Environment Day is celebrated on June 5 every year to spread awareness about environment conservation as well as taking better actions to fight climate change. In this blog, we bring you the 25 best slogans for World Environment Day 2021 that you must check out!
