No water, no life, no blue, no green.
The ocean and fishes are the essence of human life, more than 3 billion people rely on wild caught and farmed sea food but how is this dependence affecting the ocean’s ecosystem? and is this large demand causing more harm than good?
Overfishing menaces the world’s ocean.
Since the 1800, the world witnessed the first overfishing incident when humans were seeking blubber for lamp oil and obliterated the whales around Stellwagen Bank in the United States. The problem accelerated in the 1930s, when subsidies and loans were granted for fishing and thus the appearance of big industrial fishing operations. In 1989, the industry has reached its peak by taking 90 million tons of fish from the ocean and after that yields began to stagnate or decline. We encountered a 30% decrease from 1989 and 1990.
Overfishing is causing fishes to go extinct where 1,616 fishes are on the verge of being extinct, 989 are endangered and 627 are critically endangered. Overfishing has caused a huge collapse of large fish population. The fishing industry began “fishing down” which created a bycatch problem, since when you throw a net, everything gets pulled including diverse not intended species such as sharks, turtles, dolphins…
Overfishing can be controlled through limiting the number of catches and increasing aquaculture and farming of seafood, where most of the world’s growth in aquaculture production has come from East Asia and the Pacific. In addition, fisheries management is implemented to make and impose the rules in order to prevent overfishing.
Overfishing is a major problem! And it is not going away by itself. As former president Bill Clinton said “we know that when we protect our oceans, we are protecting our futures”. Therefore, we recommend declaring certain areas banned for non-sustainable fishing and to bring more awareness to consumers over the type of fish they are buying if it’s from a sustainable source or a non- sustainable one.
However, will this be enough? is aquaculture a solution to our problem? or the beginning of a new one?

Life on Land
Earth is our home, our planet is home to every lifeform we know, these come in all shapes and sizes, from the most unfamiliar one to the one that you see every day. Sometimes we don’t act always good for each others and we considered each others as predators and prey. But we share the same roof, the same air, the same planet and we depend on each other for food and sustainability especially because in the most cases we share our habitats in close proximity.
To survive we should maintain our plant rich in biodiversity. As we have needs as humans, the nature has it owns and we must be careful not to harm any animal nor plants because this will affect us directly. Why?
It will be clear by the life chain representation: Plants (Flora) -> Animals (Fauna) -> Humans
Unfortunately, more than 200 species go extinct, If we don’t act species like the Asian elephant, Siberians tiger will continue to vanish until they are gone. The First 4 Graphs in the Dashboard reflect the dangerous situation for both flora and fauna , the number of threatened species is increasing hugely from 2017 to 2018 for Birds (More than 2,000 new species), Plants(More than 2,000 new species), Mammals(More than 400 new species) and Fish(more than 1,000 new species).
Biodiversity start in the distant and points towards the future
Well I guess Frans Lanting quote is sufficient to understand the importance of biodiversity for our future existence.
We might ask ourselves what is the main reason, and I’d like to take this opportunity to think what humans did for animals and plants habitat? Protecting wildlife habitats? Of Course NOOOOOOOOO
let’s define first the net forest depletion : unit resource rents times the excess of roundwood harvest over natural growth. By examining the Net Forest Depletion graph in the dashboard this Indicator increased significantly in the world from 1971 (2,603,842,725) to reach its peak in 2019 (55,145,163,033). In addition the forecasted part confirm that we will reach a higher number in 2030, so the situation will get only worsened.
Let’s not forget that the number of threatened species in increasing hugely yearly and Approx. more than 200 new species are threatened each year and this damage is caused mainly by the unsustainable humans activities like forest depletion which they constitute the habitats for all animals and plants.
It’s never too late, Let’s build safe habitats for threatened animals (Zoo),adapt the afforestation and recycling and concerning the role of government in protecting the life on land it could be by imposing strict rules for causing any damage for animals and plants, also by reducing environmental pollution especially in the water and air.
We only have this one planet; we got to figure out how to live in it without destroying it.
Thank You
