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...

Air pollution

Hi Everyone, Today we're talking about air pollution. We've all heard about air pollution, normally in connection to cars, coal mines or planes. But what are the consequences of too much air pollution and what can we do about it? One type of air pollution is known as PM2.5. These are particles less than 2.5 micrometers in diameter. This means that we cannot see them without technology such as microscopes. They are produced in a number of different ways including power generation, motor traffic, domestic heating and chemical reactions taking place in the air around us. Although these particles are very small and "invisible", they can cause a lot of damage. Research data now shows links between this form of air pollution and cancers, premature births, diabetes (especially type 2) and heart and lung disease. It is shown to cause 400 000 deaths across Europe every year. Unfortunately this form of air pollution is widespread. A guardian article explains how in Europe alone...

Coral reefs

Hello! We would love to introduce you to the topic of coral reefs and especially coral reef bleaching, as it is a greatly ignored but certainly significant topic. Have fun! 5 coral reef facts 1. The Great Barrier Reef is the largest living structure on the planet and is 2300 km long! 2. Less than 0.1% of the world's ocean surface is covered in coral reefs. 3. At least 25% of all marine animals live there. 4. Coral reefs are often known as the rainforests of the ocean. 5. In 1 square kilometre of coral reef, up to 35 tons of fish can be 'produced'. The 5 biggest coral reefs in the world 1. Great Barrier Reef (near Australia) 2. Red Sea Coral Reef (near Egypt, Israel and Djibouti) 3. New Caledonia Reef (Pacific Ocean near New Caledonia) 4. The Mesoamerican Barrier Reef (near Mexico, Belize, Guatemala and Honduras) 5. Florida Reef (Atlantic Ocean/Gulf of Mexico near Florida) What is coral? Coral is actually made up of small anim...

November Top Tips | sustainable activities and hobbies

Hello everyone, So this week, we are going to be talking about sustainable free time activities. This area can quite big when it comes to environmental impact, so here are some things that you can do in your free time, that are more sustainable. 1. Reading So reading is one of our favourite things to do. However, books are made of paper and the paper industry isn't great. Some ways you can get around this is by reading online (for example, on a kindle), or through borrowing books from a library or using book boxes. If there aren't any in your area then at least try to support independent bookshops! 2. Running If you love being active then this one is for you. Running is probably one of the most sustainable forms of sport. All you need are some running shoes and somewhere to run. There is obviously more high-tech gear but that isn't really necessary if it's just a hobby. 3. Gardening If you've got a small area of land o...

Green Pets: meet two new additions to my house plant family

Hi Everyone! This is a bit of a shorter post today but I have two new house plants! I love my new green pets so today I wanted to share them with you! >Neither of them have names yet so any suggestions welcome and appreciated :) Pilea: I love my new Pilea! My mum has one and managed to grow another from it and gave it to me. I also put it in a pot which originally had my Aloe Vera in it, but it grew too big! Anyway, I'm so glad my Pilea could find a home in it! I love the way this plant looks and it makes me very happy to look at! I actually don't know the name of the second one - I will insert it when I have found it! I got this one from my aunt in France who has one and made a cutting for me. I'm not sure if it'll survive but we'll see - it's certainly well-travelled! I'm not giving up hope yet and even if it doesn't make it she said she could cut me a new one! I will update on this ...

The life of ... a koala

Hello everyone, Today we're talking about koalas. Also known as koala bears, koalas are marsupials. So they're actually not bears. Koalas, phascolarctos cinereus , are tree dwelling and probably best known for spending most of the day sleeping. They live for up to 15 years in the wild although captive koalas generally live for longer. Koalas have a stout, gray body and a cream-coloured chest. They have a broad face, small yellow eyes and big fluffy ears. In adaptation to climbing, their feet are strong and clawed. Adult individuals in South Australia weigh 14kg and are 60-84cm big. Their Eastern cousins are considerably smaller. Koalas are found in Eastern and Southern Australia, where they live in eucalyptus trees. They feed on the leaves of these eucalyptus trees, eating up to 1.3kg a day. With a body weight of up to 14kg, this means they eat just under 10% of their body weight every single day. However, the le...

Evolution

Hi, So today, I am going to talk about evolution. We have mentioned this before in our Galapagos Ecosystem series but we’ve never gone over exactly what it is. So before Charles Darwin thought of his theory of evolution, the majority of people in Europe thought that all species were unrelated and that humans were not related to animals. This was mostly based on Christianity. Darwin studied hundreds of different species and on the Galápagos Islands , he first started to form his theory of evolution. Darwin's theory of evolution by natural selection, as it was later called, is best explained by the example of the giraffe. Let's assume that giraffes have short necks (as they did many centuries ago). Now a mother has two children. By chance, one has a slightly longer neck. This is a coincidence. As the giraffes feed on the lower leaves of the trees, these slower disappear. There aren't enough leaves for the giraffes. Thus the giraffe wi...

Sustainable food choices challenge

Hi everyone, Welcome back to our second challenge! Today we're talking about sustainable food choices. 1. No meat on Mondays challenge The production of meat, especially beef, is resource-intensive and contributes significantly to deforestation, greenhouse gas emissions, and water pollution. By dedicating one day a week to plant-based meals, you can decrease your carbon footprint and help to reduce the strain on natural resources. This challenge encourages a more sustainable and ethical approach to food consumption, gaining a better understanding of the environmental impact of meat production. Reducing meat intake is also associated with health benefits, including lower risks of heart disease and certain cancers, making it a win-win for both your personal well-being and the planet. 2. Local / seasonal eating challenge Choosing local and seasonal foods is important in helping to reduce the environmental impact of food production and transporta...

Green Pets || easy house plants to get you started // best house plants for beginners

Hi Everyone! Today I wanted to talk to you about some easy house plants you could look after to get you started on your green pets journey. These are plants that are easy to look after and that I recommend for an introduction into caring for house plants. If you are a beginner or want to look after some plants, then this is the post for you! 1. Cacti - moon cactus I don't actually have a cactus, but they are the obvious place to start. They need little water and thrive in warm conditions; they are described as "low maintenance". I have done some research and it looks like the moon cactus (Gymnocalycium mihanovichii) is the best one in terms of not being too fussy with needing minimal water and tolerates lower light levels. I would like a cactus at some point, but if you are just starting out wanting to care for some house plants, then this is the one to start with! 2. Aloe Vera One of my first house plants, this is one that is rela...

Jane Goodall

Born: 1934 When Jane was a little girl, she loved climbing trees and reading books. She dreamed that she could go to Africa and see the wild animals there. So Jane flew to Tanzania determined to study chimpanzees in their natural habitat. When she first arrived, none of the chimpanzees would let her get near them. They would always run away at first sight. Jane kept coming back until they let her come closer. However, Jane wanted to become friends with the chimpanzees. So she started the "banana club" which meant that she would share bananas with them every time she visited the chimpanzees. She discovered that chimpanzees have rituals, that they use tools, that their language comprises at least twenty sounds and that they are not vegetarians. Once she rescued an injured chimpanzee and nursed it back to health. When she released it back into the wild, the chimpanzee turned around and hugged her as if to say, "thank you and goodby...
