Celebrating World Environment Day

Introduction
 

World Environmental Day is annually celebrated on the 5th of June and is the most commemorated of all the environmental awareness days in over 100 countries. In 1972 the UN General Assembly chose June 5 as World Environment Day (WED), marking the first day of the Stockholm Conference on the Human Environment. It is a platform for public outreach to stimulate and deepen global awareness of the need to care for, preserve, and enhance Mother Nature. It is a day to acknowledge and personalise environmental issues and to evoke positive environmental action amongst all people. It inspires individual and collective action to do something positive for the environment, to realise that each of us has a responsibility to protect to it from further destruction, and to take care of it indefinitely.
 
People must become environmental agents of change. Notably, it is also a day to learn more about ways that people can help to ensure the future of our planet is safe and a cleaner and greener outlook for not only themselves, but, more prominently, for future generations to make greener lifestyle choices and support sustainable and equitable development. It is also known as the ‘people’s day’ for doing something to take care of the Earth. It puts a spotlight on all the achievements and effective actions that have been implemented to protect life-nurturing Mother Nature.
 
Each year a different global country is assigned as the host of WED where official celebrations occur and this year’s host is Angola. A greater emphasis is placed on the environmental challenges that this specific country is faced with and support is provided in an effort to address them.
 
Importance of WED
As a result of decades celebrating this momentous day, millions of people from all over the world have participated in imperative environmental action. Furthermore, it is celebrated to look at all the achievements that have been made towards protecting the environment. It reminds individuals and countries of the importance of caring for our environment. It encourages societies to actively participate in becoming an agent in curbing negative environmental impacts.
 
Being a part of the celebrations, it provides an opportunity for people to share ideas and activities to make the world a better, environmentally-friendly place. As the official WED 2016 website reminds as, “Remember that every action counts, so join us: every year, everywhere, everyone!”
 
Theme
Each year a specific theme for WED is chosen by the United Nations to promote awareness on a specific and pressing environmental issue. WED 2016’s theme is: The illegal trade in wildlife under the slogan ‘Go Wild for Life’.
 
Wildlife not only faces man-made and natural threats such as climate change, habitat loss, and collisions with vehicles, but also one incredibly yet totally avoidable danger: the lucrative illegal wildlife trade. Huge profits can be made from ivory and rhino and is a very attractive commodity. This year focuses specifically on highlighting the dangers illegal wildlife trade has on our wellbeing. This illegal yet booming trade is fast eroding Mother Nature’s precious biodiversity but it is depriving us of our wonderful natural heritage. If this trade isn’t curbed swiftly, extinction is imminent. Furthermore, the killing and smuggling undermine economies and ecosystems. Through this senselessly shocking practice, elephants, rhinos, tigers, gorillas, and sea turtles are threatened. Other lesser-known species that are also negatively impacted include helmeted hornbills, pangolins, wild orchids and timbers like Rosewood. Notably, efforts to counter this illegal trade, including stronger policies, awareness campaigns and investments in community conservation and law enforcement, have occurred. But a lot can still be done.
 
It is important to convey a zero-tolerance for this illegal trade. This year all people are encouraged to celebrate those species that are under sever threat in order to take action to help safeguard them for not only current, but also future generations to come.
 
The rationale behind this year’s theme is that the illegal trade in wildlife will ultimately lead to extinction (both at a local and global scale) of many animal and plant species. The extinction of elephant, tiger and sea turtle species will be detrimental for conservation efforts. Wildlife crime is a rising threat to economies and communities, especially in developing countries. The loss of a species is a destruction of the biodiversity that supports the natural systems and on which we depend for food security, medicines, fresh air, water, shelter and a clean environment. By reducing human-wildlife conflict and, simultaneously, engaging communities in conservation efforts, there will be an increase support for wildlife protection and provide incentive to reduce poaching.
 
Facts on illegal trade on wildlife
 
·        100,000 African elephants were killed in 2010-2012, out of a population estimated at less than 
      500,000.
·        Illegal trade in wildlife is worth $15-20 billion annually, and is one of the largest illegal trades in the world.
·        Poachers in Africa killed at least 1,338 rhinos in 2015, according to the International Union for Conservation of Nature (IUCN).
·        Rhino poaching in South Africa increased by almost 9,000% or 90-fold between 2007 and 2015 from 13 rhinos killed in 2007 to 1,175 rhinos killed in 2015.
·        An estimated 170 tonnes of ivory was illegally exported out of Africa between 2009 and 2014.
·        Between 2002 and 2011 there was a 2/3 plummet in Forest Elephant population due to poaching.
·        Since 2009 there has been a 60% decline African Savannah Elephants in the United Republic of Tanzania and a 50% decline in African Savannah Elephants in Mozambique.
·       Chimpanzees are now extinct in Gambia, Burkina Faso, Benin and Togo.

Delightful Dolphins

Dolphins are extraordinarily intelligent marine mammals and one of the most iconic species of the marine world. Here are just a few more interesting facts about these fantastic species:

Source: HD Animal Wallpapers
 ·         Dolphins are part of the family of toothed whales that includes orcas and pilot whales.

·         Their coloration varies, but are normally grey in colour with darker backs than the rest of their bodies.

·         There are 43 different species of dolphins that have been recognized.

·         The body of a dolphin is designed to help them move through the water quickly and without exerting huge amounts of energy. They rely on their pectoral fins and the fluke (tail) to help them navigate through the water.

·         Echolocation allows them to communicate in the water by identifying sound waves. It is a complex ability that stems from the melon that is located in the head of a dolphin.

·         Dolphins have very good vision, and they are able to see what is around them both in the water and when they are above the surface of it.

·         They have excellent hearing with the ability to hear about 10 times better than humans.

·         The sense of smell isn’t well developed for them though.

·         The sense of touch is very sensitive for dolphins and they use it for bonding within their pods.

·         They rely on a combination of their senses to avoid danger, to find food, and to socialize.

·         The name dolphin comes from the word womb, and it is believed to be the Greek saying for fish with a womb.

·         The young are called calves

·         The female adults are cows.

·         The male adults are bulls

·         A group of them is often called a pod.

Diet
·         Dolphins are carnivores

·         They consume an assortment of prey including fish, squid, and crustaceans.

·         They use echolocation to find prey and often hunt together by surrounding a school of fish, trapping them, and taking turns swimming through the school and catching fish.

·         Dolphins will also follow seabirds, other whales, and fishing boats to feed opportunistically on the fish they scare up or discard.

·         Even though dolphins have 100 teeth, they don’t use them for eating. They do use them to get the fish though and then they swallow them. They can consume up to 30 pounds fish per day.

·         They do what is necessary to get the food for the pod members. It can include jumps, zig zag patterns, circles, and a combination of efforts.

·         With an exceptionally high fat content, dolphin and other cetacean meat provides great nutrition for predators who stalk.

Size
The larger ones can weigh about 11 tons and be close to 30 feet long. The smaller ones are about 90 pounds and 4 feet long. Between those two spectrums you will find all weights and lengths. The species as well as their location play a huge role in their overall size.

Range
·         They are found typically in shallow seas of the continental shelves.

·         Most species live in shallow areas of tropical and temperate oceans.

·         Five species live in the world's rivers.

·         Most of the species of dolphins live in saltwater but there are some that are able to do well in the freshwater locations.

·         They are mainly found in the freshwater of the Amazon River.

·         They tend to live in the shallow water by the coast and they tend to live in warmer locations.

Behaviour
·         Dolphins are well known for their agility and playful behaviour

·         Many species will leap out of the water and spy-hop (rise vertically out of the water to view their surroundings). Some of them leap up to 30 feet in the air.

·         Dolphins live in social groups of five to several hundred.

·         They have to come to the surface to for water at different intervals to get air. This can be from 20 seconds to 30 minutes between when they get air.

·         They are curious.

·         To prevent drowning while sleeping only half of the dolphin’s brain goes to sleep while the other half remains awake so they can continue to breathe!

·         They form strong bonds within their pod.

·         They have been known to help humans in a variety of circumstances including rescues and with fishing.

·         Dolphins are extremely social creatures and actually seem to depend on this interaction while hunting, mating, and defending themselves and their pods.

Reproduction

·         Mating Season: Throughout the year, though in some areas there is a peak in spring and fall.

·         Gestation: 9-17 months depending on the species. When it is time to give birth, the female will distance herself from the pod, often going near the surface of the water.

·         Number of offspring: Usually one calf; twins are rare.


Source: PC Wallpapers
·         As soon as the calf is born, the mother must quickly take it to the surface so it can take its first breath. The calf will nurse from 11 months to 2 years, and after it is done nursing it will still stay with its mother until it is between 3 and 8 years old.

·         Dolphins give birth to live young, and nurse them with mammary glands, though it boggles the mind to imagine nursing underwater.

Theme for Earth Day 2016: Trees for the Earth

The theme of this year's Earth Day is: Trees for the Earth. 

Earth Day is annually celebrated on 22 April. It marks an important environmental day that is celebrated all over the world. The Earth Day Network aims to plant 7.8 billion trees. The organisation notes that "trees will be the first of five major goals we are undertaking in honor of the five-year countdown to our 50th anniversary". These positive initiatives will impact the environment which will ultimately lead to a cleaner, healthier and more sustainable planet for all.

There are several reasons why trees were chosen, mainly because (Earth Day Organisation 2016):
  • Trees help combat climate change. They absorb excess and harmful CO2 from our atmosphere. In fact, in a single year, an acre of mature trees absorbs the same amount of CO2 produced by driving the average car 26,000 miles.
  • Trees help us breathe clean air. Trees absorb odours and pollutant gases (nitrogen oxides, ammonia, sulfur dioxide and ozone) and filter particulates out of the air by trapping them on their leaves and bark.
  • Trees help communities. Trees help communities achieve long-term economic and environmental sustainability and provide food, energy and income.
