World Environment Day Special Quiz

Global wildlife trafficking is a lucrative criminal activity.What is currently the most trafficked mammal in the world?


B) Pangolin

C) Lemur

D) Great Ape


LEARN MORE: Pangolins are small nocturnal mammals, rangingin size from 30-100 centimetres, found in tropical regions throughout Africa and Asia. They have no teeth and are unable to move very quickly, but pangolins have a very special defense mechanism,including sharp, overlapping scales. When they are approached by predators,pangolins roll themselves into a ball, and these scales function like a suit of armour. In fact, their name is an adaptation of the Malay word, pengguling-which means "something that rolls up". They are the world's only Scaly mammal. Pangolins are threatened by deforestation of their natural habitats. They are hunted for their meat and Scales and they are the most frequently trafficked mammal in the world. of the eight species of pangolin, four are vulnerable, two are endangered, and two species are critically endangered, according to the International Union for the Conservation of Nature Red List of Threatened Species. International Trade in all eight species is illegal under CITES

2) What percentage of the planet's land is covered by forests?






LEARN MORE: While forests occupy less than a third of the Earth's surface, they are home to more than 80 per cent of all terrestrial species of animals, plants and insects; serve as a source of livelihood to more than a quarter of the world's population; offer sources of medicine; and soak up carbon dioxide. Globally, however, deforestation continues at an alarming rate, with 7 million hectares of forest destroyed every year - an area roughly the size of Portugal.

Of the plants grown for human consumption, approximately what percentage is pollinated by animals?





The correct answer is 75

LEARN MORE: Pollination is the fertilization process required by plants to reproduce. Eighty-seven of the leading 115 global food crops depend on animal pollination. This includes many of the foods we consume-berries, nuts, avocados, coffee and chocolate, among others. In economic terms, the contribution of pollinators to agriculture has been valued at more than US$200 billion per year Birds, insects and even small rodents are common pollinators, but some very large animals also pollinate plants. The black and white ruffed lemur, a mammal that can weigh up to 4kg, is the world's largest pollinator. Natural habitats provide diverse plant species, which flower at different times of the year, so food is consistently available to pollinators. However, great expanses of land are being converted to farmland with crops that only flower at certain times of year. The sporadic availability of food and lack of places to nest has caused many pollinators to die.

3) Approximately how many million people live in the Amazon rainforest?





Forest fires happen in the dry season (July-October), and as a result of natural ocurrences such as lightning strikes. However, fires are sometimes started intentionally and trees are often cleared to make space for industrial activities and large-scale agriculture. Today, it is estimated that more than three-quarters of Amazon forest-clearing is for the purpose of cattle-ranching.

Of all mammals on earth what percentage are wild?





Ihe correct ansWer is 4

: A study published in the Proceedings of Natural Science shows that farmed poultry today makes up 70% of all birds on the planet, with just 30% being wild. The picture is even more stark for mammals - 60% of all mammals on Earth are livestock, mostly cattle and pigs, 36% are human and just 4% are wild animals. Population growth, urbanization and improved incomes have driven consumer demand for meat and dairy products. Today, 60 per cent of all mammals on Earth are livestock and, the majority of which is cattle and pigs. Livestock produces greenhouse gas and represents 14.5 per cent of all Population growth, urbanization and improved incomes have driven consumer demand for meat and dairy products. Today, 60 per cent of all mammals on Earth are livestock and, the majority of which is cattle and pigs. Livestock produces greenhouse gas and represents 14.5 per cent of all anthropocentric emissions. Cattle are responsible for the most emissions, producing about 65 per cent of emissions from livestock.

In many areas, what percentage of coral cover

has died in the past 30 years?





The correct answer is 50

: Coral reefs are home to 25 per cent of marine life and are a major source of food to more than half a billion people. Every day, drugs derived from coral reefs are dispensed around the world for treating diseases such as cancer, arthritis, human bacterial infections, and viruses. The collective value of coral reefs is estimated at US$365 billion per year and tourism alone accounts for $36 billion in revenues, as travellers enjoy diving and snorkelling among coral Reefs. They also provide physical structures that dissipate wave energy,

What are diatoms?

Particles of dust that cause cancer in humans

A type of microscopic algae

Tiny particles of silica in the oceans

A species of grass that absorbs


The correct answer is'A

type of microscopic algae'

: Diatoms are a type of microscopic algae found in the ocean, waterways and soils. Their ornate cell walls are composed of silica-the same compound used in the production of glass. For this reason, diatoms are said to "live in glass houses." Through photosynthesis, diatoms produce roughly between 20 per cent and 40 per cent of the oxygen we breathe.

Of all the species protected by the Convention on the International Trade in Endangered Species, what percentage are plants?





The correct answer is 84

LEARN MORE: Of the 35,800 species protected by the Convention on the International Trade in Endangered Species, 30,000 are plants. It is estimated that there are 8 million species of plants and animals on Earth. However, we are losing species 1,000 times faster than at any other time in recorded human history. Up to 1 million animal and plant species are currenty threatened with extinction - many within decades.

Which of the following statements is not true?

There are around 100 species of


Bats are the only flying mammal.

Bats are night pollinators.

Bats serve as natural pest control


LEARN MORE: There are actually more than 1,100 species of bat. Of these, only three species are vampire bats and, contrary to modern myth, they rarely bite humans. In fact, bats are very helpful to humans. Their droppings are high in phosphorous and nitrogen, and serve as a fertilizer in many tropical regions. Every year, bats spread millions of seeds after ripe fruit passes through their digestive tract; and about 95 per cent of reforestation in the tropical rainforest is a result of their seed

Of all the species on Earth, approximately what percentage have we identified?





The correct answer is 10

: Of the 8 million species on the planet, we have identified no more than about one in ten. Every species draws from and contributes to the ecosystem in which it exists, in ways we may not even see. Whales store carbon from the atmosphere. Species like the helmeted hornbill and many other birds fly thousands of miles and disperse seeds that enable forests to provide myriad food sources. Many tree species are germinated through the digestive systems of elephants. Pangolins aerat soils to maintain soil health; and control pests eating up to 20,000 ants and
