The 15 Most Beautiful Coral Reefs In The World

Humans play an important role as one of the top predators in these food webs. It is our responsibility to ensure that our fisheries are sustainable and that we are not polluting the ocean with toxins that bioaccumulate in food webs.

Without reefs, billions of sea life species would suffer, millions of people would lose their most significant food source, and economies would take a major hit. But it’s not just about the jobs. Coral reefs attract tourists to more than 100 countries and territories worldwide.

Coral reefs are endangered by a variety of factors, including: natural phenomena such as hurricanes, El Niño, and diseases; local threats such as overfishing, destructive fishing techniques, coastal development, pollution, and careless tourism; and the global effects of climate change—warming seas and increasing levels …

As a result, over 50 percent of the world’s coral reefs have died in the last 30 years and up to 90 percent may die within the next century—very few pristine coral reefs still exist. The impact of our changing climate on coral reefs was manifested by the third global bleaching event in 2015/16.

• Great Barrier Reef – Australia. Natural Feature.
• New Caledonia Barrier Reef – New Caledonia.
• Red Sea Coral Reef – Red Sea.
• Rainbow Reef – Fiji.
• Tubbataha Reefs Natural Park.
• Raja Ampat – Indonesia.
• Palancar Reef – Cozumel, Mexico.
• Great Chagos Archipelago – Indian Ocean.

Under the Endangered Species Act, 22 coral species are listed as threatened, and three are listed as endangered. The primary threats to coral reefs are climate change, pollution, and impacts from unsustainable fishing.

Nearly All Coral Reefs Will Disappear Over The Next 20 Years, Scientists Say. Over the next 20 years, scientists estimate about 70 to 90% of all coral reefs will disappear primarily as a result of warming ocean waters, ocean acidity, and pollution.

10 Surprising Marine Animals Close to Extinction

• Scalloped Hammerhead Sharks. Conservation Status: Endangered.
• Hawksbill Sea Turtle. Conservation Status: Critically endangered.
• River Dolphins.
• Mako Sharks.
• Galapagos Penguin.
• Humphead Wrasse.
• Hawaiian Monk Seal.
• Giant Devil Ray.

Extinct species

• Longjaw cisco (Coregonus alpenae)
• Coregonus bezola.
• Coregonus fera.
• Coregonus gutturosus.
• Gravenche (Coregonus hiemalis)
• Deepwater cisco (Coregonus johannae)
• Blackfin cisco (Coregonus nigripinnis)
• Houting (Coregonus oxyrinchus)

Persoonia laxa—This shrub from New South Wales, Australia, was collected just two times—in 1907 and 1908—in habitats that have since become “highly urbanized.” The NSW government still lists it as “presumed extinct,” but the IUCN placed it fully in the “extinct” category in 2020.

The ocean will no longer be able to perform many of its essential functions, leading to a lower quality of life. People will starve as they lose one of their main food sources. The effects of a world without fish in the sea would be felt by everyone.

Freshwater fish populations are collapsing. Nearly 1/3 of all freshwater fish are threatened with extinction. In 2020 alone, 16 freshwater fish species were declared extinct. Since 1970, mega-fish—those that weigh over 66lbs—have declined in number by 94% and migratory freshwater fish saw a 76 % decline.

According to study seafood could be extinct in the next 30 years. A study from an international team of ecologists and economists have predicted that by 2048 we could see completely fishless oceans. The cause: disappearance of species due to overfishing, pollution, habitat loss and climate change.

It would lead to major repercussions, affecting marine life as well as all forms of life including humans. Fish extinction would cause changes in the weather, disruption of aquatic ecosystems, poverty, hunger, economic losses, and overall chaos. This article will help you understand just how serious a problem this is.

Almost all tropical fish commonly kept in the home aquarium can easily go at least a few days without being fed. While a collection of large, healthy cichlids can easily go seven to 10 days without fish food, an aquarium full of baby fish will need to be fed after a day or two.

Don’t Feed Your Fish As for food, freshwater fish are quite capable of going for several days without a meal. Healthy adult fish can go for a week or two without feeding. However, young fish don’t have the fat stores of adult fish and they cannot go without eating very long.

As for whether the fish can handle a fast day, yes they can. Just like we can go a day without eating, so can a healthy fish. We and they can both go even longer than just 1 day.

Feeding tropical fish every second day is okay, provided they’re not frye. Baby fish, however, need to be fed twice a day. Adult fish can be fed every other day and in doing so, you’ll help ensure that tank environment remains safe for all inhabitants.
