16.08.2020 Animal of the week: Elephant

Hello. On the 12th of August it was International Elephant Day, so we decided that this week's post should be about elephants. Elephants are the largest living land mammals. There are three types of elephant; the African bush elephant; the African forest elephant and the Asian elephant. African elephants have larger ears, whereas Asian elephants have smaller ears. Elephants use their trunks to breath, bring food and drink to their mouths and to grasp objects. Elephants' legs are like pillars. They carry the Elephant's massive weight. African bush elephants weigh 6000kg, Asian elephants weigh 4000kg and African forest elephants weigh 2700kg. Basically, they are very heavy.Elephants eat grasses, small plants, bushes, fruit, twigs, tree bark, and roots. Elephants can live up to 70 years old in the wild. They communicate by sight, touch and smell. Sadly, these wonderful mammals are in danger. African elephants are listed as vulne...

Ozone layer

Hi everyone, What even is ozone? And the ozone layer? Where does the hole in the ozone layer come from and what does it mean? Is it dangerous? What can be done? Often the ozone-talk can be complicated and confusing, keeping an overview is hard and understanding all the problems always difficult. Let us break it down a bit for you: What is the ozone layer? We'll start with the basics: The ozone layer is part of the stratosphere, which is the second layer of the Earth's atmosphere, between 10 and 50 km above the Earth's surface and made up of protective gases. One of these protective gases is ozone. There is not much ozone in the atmosphere, only 0.3 molecule of ozone per 1 million molecules of air. This is because ozone is chemically unstable and only forms when ultra violet radiation (UV light) hits oxygen and breaks the bonds between the atoms. It fact it is so unstable that even when it has formed, it breaks down again relatively quickly. This leads to ozone turning back ...

10 animals on the edge of extinction you didn't know about no. 9 - South Island takahē

Hello Today we’re talking about the South Island takahē, porphyrio hochstetteri . They are flightless birds, endemic to New Zealand. Takahē are brightly coloured and weigh 2.3-3.8 kg. They have red legs and a large red beak. Their feathers are coloured blue and green. They have wings, but these are only used during courtship or rivalry displays. They are territorial, with one family’s territory reaching anywhere from 4 ha to 100 ha (0,04-1km^2). Pairs will live in the same territory each year. They breed once a year and will raise 1-3 chicks (normally 2) each year. Both parents raise the chicks together. In the wild, takahē live in native grasslands and have a lifespan of 16-18 years. If snow covers the ground then they will move into nearby forests. They eat tussock grasses, sedges and sometimes rushes. But they are opportunists, so they will occasionally go for insects or even ducklings and...

The Responsible Traveller by Karen Edwards || a practical guide to reducing your environmental and social impact // BOOK REVIEW

HI Everyone! Our January monthly post was a zero-waste challenge, but as we explained in our 2023 wrap up , this year we will be alternating a monthly challenge with a book review, of course related to the environment. This week, I'm going to share a recommendation for a fantastic book, all about how you can travel more sustainably and responsibly. I absolutely love travelling, but I'm also very aware of the impact it has on the world, and I am very keen to learn more about how I can further reduce my impact. That's why I bought this book around a year ago, and I've really enjoyed reading it and learning from it. This is a practical, small-format guide, sharing both basic information about the climate crisis and the impact of various travel activities, and how you can do your bit. It shares specific journeys that are more environmentally friendly options, for example long distance train journeys such as The Alaskan Railroad with its stunning alpine forests and wide ar...

Pollination

Hello everyone, Today we're talking about pollination and its importance in the world's ecosystems. First a bit of basic plant biology. To reproduce most plants do have a differentiation into male and female, but not in the same way that we see in mammals. Both male and female reproductive organs can be found on the same plant, although not in the same place. Male gametes are produced in the stamens and are then found in pollen. On the other hand, female reproductive organs are called pistils and egg cells are found in the ovule (normally in the flower heads). Pollination describes the process of transporting the pollen to the egg cells, making it an essential part of the reproduction of plants. Nearly all seed plants worldwide require pollination to reproduce. Cone bearing trees also need pollination. Pollination is almost always assisted by other organisms such as insects, birds and mammals to transport the pollen. In some species wind ...

Biodiversity

Hello, Today we're talking about biodiversity and why it's so important. As you probably know biodiversity describes the variety of living species, often referring to one specific place or ecosystem. For example, the Amazon rainforest is a very biodiverse ecosystem. The opposite of biodiverse is a monoculture. A monoculture often refers to farmland, where only one crop is produced. Palm oil plantations are normally monocultures, with rows and rows of palm trees and nothing else. I'm going to start by giving you an idea of the current situation. This year, the State of Nature 2023 report was published. This report looks at recent changes in biodiversity in the UK. To be frank, it's bad news. One in six (17%) of all UK species and almost half (43%) of bird species are at risk of extinction. 31% of amphibians and reptiles and 28% of fungi are also at risk. There has been a 54% decline in flowering plant species and a 34% decline in ...

Carbon credits

Hi everyone, Welcome back to Green World! Today we're talking about an industry that has expanded massively in the past few years. Carbon credits are one of the measures that companies are taking to reduce CO2 emissions . But how does it actually work? The companies that sell carbon credits fund projects to protect an area of forest or rainforest from deforestation . They then calculate how much carbon dioxide emissions they have saves by protecting this area. This means they can now sell 'negative carbon emissions' to companies. In this way, the companies are funding the protection of said area and are causing negative emissions while doing so meaning that the company can still emit greenhouse gases but can claim to be net zero. One carbon credit is basically the permission to emit one ton of CO2. This is good for the company as well as they are able to advertise as sustainable at a relatively low cost to actually reducing the...

Ecotourism: what it is, the advantages and the disadvantages

Hi Everyone! Today we wanted to talk about the idea of ecotourism, including the advantages and disadvantages of this concept. If you are looking to reduce your environmental and social impact when travelling, then this is the post for you! Ecotourism is a form of tourism which limits the damage to the environment and local community. It can involve helping in community projects such as planting trees, as well as taking part in local customs and festivals. It helps to keep the local culture alive, while preserving the natural environment. The advantages are abundant. By helping in a project conserving the environment, tourists gain a new understanding and appreciation for the natural world and may be inspired to make changes in their "real" life to live more sustainably. It provides a valuable insight to a country and community, perhaps also inspiring more respect for different people and the lives they lead. The projects also provide sustainable income sources for locals, h...

Zero-waste Challenge

Hi everyone, Welcome back to Green World for our first post of 2024! As explained in our wrap up post, this year the monthly series will switch between challenges and book reviews. We're starting with a challenge and this month we're challenging you to cut down on your waste! 1. No single use plastic bags challenge Plastic bags are a disaster for the environment and they're not always even usable for us. Some of the really thin plastic bags will just rip as soon as you put something in them which is a nightmare if you're out shopping and need to transport your groceries home. When these plastic bags are then thrown away, they cause significant damage to our planet. Plastic bags often clog waterways and sewers which is a massive problem. Waterways, such as streams, and their ecosystems depend on moving water and if they get too blocked, the migration of different species is hindered. If a dam starts to form with all of the sticks, rocks and more plastic that is being tr...
