Action and Mission of ecology
Ecology studies living things in their environment taking into account their interactions.
This set, which contains living things, their living environment and the relationships they maintain, forms an ecosystem.
The goal of ecology is to detect, analyze and combat possible ecosystem dysfunctions. It also seeks for human well-being in the form of harmony with its natural environment.
The environment is composed
– living things (fauna and flora) as well as
– non-living beings that are mineral components (water, rocks and invisible air).
These different components are not independent. They establish relationships that are indispensable to the life of living things.
Relationships of all kinds are established between one living being and another, between a living being and a mineral element.
The main mission of ecologyisto work to protect the environment in order to “save the planet”.
In order to have a real impact around theworld, several volunteers are active in many sectors to carry out joint actions.
DEFORESTATION CONSEQUENCES. Forests absorb a lot of sunlight for photosynthesis and only about 12 to 15% are reflected. … Trees also absorb carbon dioxide from the atmosphere for photosynthesis, and thus help regulate thenatural green house effect.
Deforested areas can eventually turn into deserts (this is desertification). Finally, the water vapour released by forests helps to increase air moisture and promotes rainfall. Deforestation can therefore reduce the amount of rainfall and cause droughts.
Consequences of climate change:
Extreme weather events such as storms, droughts, heavy rainfall… happen more and more frequently. The seasons have become very unstable, which has, among other things, consequences on agriculture and on flora and fauna.
To remedy this, planting trees becomes an emergency.
The usefulness of trees: Thetree is an oxygen producer, air purifier and source of life: Trees,carbon sinks sequester CO2 (carbon dioxide) in the atmosphereand then transform it and release it into oxygen. … Trees emit molecules (VOC: volatile Organic Compound) that serve as germs.
According to researchers, planting trees would help absorb two-thirds of the carbon in the atmosphere and there is enough space in the world to plant all these trees. On the same hand, a team of researchers from the University of Zurich even estimates that planting billions of seeds would be an ultra-effective remedy against CO2 emissions,which are responsible for the runaway mercury.
Sothere is no doubt, green is the color of hope and the symbol of healing, so the planet has everything to gain from draping itself ingreen.
Reforestation campaigns are beginning to make their effects felt. Fao’s biennial report, “The State of the World’s Forests,” notes a “slowing down of deforestation and an increase in forest areas in several regions.” FAO has taken stock of the fact that the “forest cover” covers nearly 4 billion hectares (30% of the world’s land area). On the one hand, 13 million hectares continue to disappear each year, but on the other, reforestation allows the balance of forest “net losses” to be established at 7.3 million hectares. That’s still 20,000 hectares a day: the equivalent of twice the size of Paris.
Ethiopia is the latest country to plant more than 350 million trees and by the end of 2019 plans to plant 4 billion trees.
This balance is fairly stable with a trend towards improvement, the UN agency points out.
As noted above, deforestation also has a big impact on agriculture.
The best solution to feed humanity today is organic farming.
Organic agriculture is not simply a “synthetic chemical-free” agriculture. It was clearly defined as an agriculture in the 1930s and 1940s that considers humans, the natural ecosystem, and the cultivated and raised agrosystem as a complex organism. It aims to put agriculture in natural cycles and give agricultural societies the means of their technical and economic autonomy.
Organic or agroecology agriculture is therefore a reformulation of the foundations of organic farming, it can be seen as a reinforcement of original organic agriculture (as opposed to organic industrial agriculture, sometimes encouraged by multinationals or too light regulations), especially in the context of tropical peasantry.
Developing organic farming requires reconstituting agricultural ecosystems and valuing peasantknowledge. It is the intensification of the associated crops that allows us to achieve the best yields per hectare. This intensification cannot use chemistry, as fertilizers destroy soil life and pesticides destabilize the agro-ecosystem; but various plants protect each other, and the combination of crops and livestock or the nesting of trees in the middle of crops helps ensure long-term fertility.
A few large-scale studies have studied the consequences of widespread organic agriculture worldwide: they all conclude that yields would decline slightly in Europe and North America but increase very sharply in the rest of the world… and that the overall balance sheet would be overwhelmingly positive.
Organic farming is the best technique to feed a humanity at 9 or 12 billion.
Organic farming is a dynamic sector that createsjobs.
Bio-sectors recruit in a wide range of sectors. Growth has been onhold for the past five years: employment in the organic sector is growing at an average rate of 9.5% per year.
One of the factors of this increase? “When you replace chemicals with human action, you need more manpower,”explains Florent Guhl, Director of the Bio Agency.
This dynamic is also reflected in the increase in organic land. This increase in surfaces will help meet the growing demand of the French for organic products.
The market for organically grown food products, an increase of 17% in one year.
