Sea turtles

Sea turtles have their habitats in all the world's oceans except the Arctic ocean. At this moment there is seven types of sea turtles in the world of which six is being listed as endangered species. Sea turtles are been on the Earth since Mesozoic but many of them are threatened with extinction all because of us humans.

Not only sea turtles are amazingly beautiful but they're also very advanced creatures with extraordinary sense for time and location and Earth's magnetic field is their navigational system.
It takes them 30 years to mature and only then adult female sea turtles return to the land to nest. Depending on turtle species female sea turtle can nest between 150-200 eggs and incubation lasts about two months. Only about 0,01 % of this eggs has a real chance to become a grown turtle one day because of many predators that lurk around.

Sea turtles are hunted almost everywhere on the world map, despite the fact that their hunting is illegal in many countries as they become food in fancy restaurants. Even in ancient times sea turtles were famous as exotic delicacies (China). But meat isn't the only hunting reason as their shell is traditional decorative ornamental material used in Japan and China.

Six out of seven sea turtles species are listed as either threatened or endangered species.

What people lack is the knowledge of these creatures significance in ecosystem and not only in oceans but on the beaches as well. If these wonderful creatures were to become extinct it could mean tremendous negative impact on oceans and beaches. Two species are already critically endangered Kemp's Ridley and Hawksbill turtles , and other species like Olive Ridley, and Green turtles aren't very far from them.

Their importance is just as vital in oceans as it is on beaches since turtles eat sea grass in ocean and sea grass must be kept short to remain healthy, and beds of healthy sea grass are essential breeding and development areas for many species of fish and other marine life and in beaches they contribute nutrients to beach (as well as dune, which is similar) vegetation from their eggs.

Many countries realized significance of these wonderful creatures and are working on laws and methods which would mean their survival. Sea turtle conservation started in 1970's and 1980's but it didn't resulted as expected since many turtles still make their way in turtle soups and some other delicacies and in Nicaragua turtle hunting has even become a way of living.

In order to help these creatures scientists studied their migration, nesting and hatching habits and mating habits to help us learn more about them so we could save them from extinction. But will that be enough? Only time will tell, but current situation isn't giving much hope.

The Sumatran rhino

The Sumatran rhino is the smallest living rhinoceros species weighing just 1,300-1,700 pounds. It has fringed ears, reddish-brown skin variably covered with long hair, and wrinkles around its eyes. It is probably the most endangered of the rhinoceros species and is the last surviving species in the same group as the extinct Woolly Rhinoceros. Numbers have declined over 50% due to poaching and habitat loss over the last 15 years. Fewer than 300 Sumatran Rhino survive in very small and highly fragmented populations in Southeast Asia with Indonesia and Malaysia being the only significant range states.

Sabah is the last preserve of the Borneo Sumatran Rhino, a subspecies of the Sumatran Rhino. WWF officials said that surveys in 1992 and 1995 in Sabah had found fewer than 13 rhinos, scattered over a vast area. While some of the Sumatran rhinos are kept in zoos, they are difficult to breed in captivity. The 2000 birth of a healthy calf to a rhino called Emi at the Cincinnati Zoo in Ohio was the first successful captive delivery in 112 years.

The Sumatran rhino are solitary animals that only come together to breed, but a 2005 survey results seem to indicate that the 13 rhinos are in an area in Sabah that’s untouched by poaching which means the rhinos have a reasonable chance to meet each other and breed. There is also evidence that there are young animals in the group so it would appear that breeding have already taken place. This has sparked hopes that the population of Borneo Sumatran Rhino can again flourish, at least in Sabah.

In this video: On April 24, 2007 it was announced that in the jungles of Malaysian Borneo cameras had captured night time footage of a Sumatran rhino eating, peering through jungle foliage, and sniffing the film equipment. The rhino in the two-minute footage is a rare Bornean subspecies of which only 25 to 50 are believed to be left on the island scientists estimate, mostly found in the dense interior jungles of Sabah, a state located on the northern portion of the island of Borneo. Although found in a commercial forest where logging is commonplace the video will be used to convince local governments to turn the area into a rhino conservation zone. This is the first-ever footage that shows the elusive Borneo rhino’s natural behavior in the wild.

Some interesting environmental facts:

Every second an area of rainforest the size of a rugby field is destroyed.

65% of all living things are found in the rainforest.

Using 1 tonne of banana fibers, to make paper instead of wood saves 17 trees.

More than 12 million acres a year of rainforest is cut down, this is bigger than the size of England, Scotland and Wales put together.

26% of humans in the world uses 86% of the earths natural materials.

Over 7.5 million tonnes of food is wasted per year, thats over £500 wasted per family.

30,000 children die each day worldwide from starvation due to lack of food.

Ask yourself is this right???

You can make a difference, there is still time if we act quickly,
just do your bit, do NOT assume somebody else will do it for you!

REDUCE your waste
REUSE what you already have before buying new stuff
RECYCLE to cut down landfill waste and to decrease the useage of new raw material used in manufacturing.
