5 Most Threatening Ecology Issues + (What You Can Do)


Ecology Issues

Are we doomed? This is the question that has been wandering around my thoughts in the past few days. It’s a hard and dark question, considering the fact, that the answer is a  burden on the shoulders of all of us. These 5 most threatening ecology issues definitely need to be popularized as well.

As a travel blogger, I often get into the point of asking myself whether what we do as tourists and travellers is sustainable and eco-friendly.

There are many issues with tourism and travel especially in countries known for their delicate nature and cultural heritage.

Tourism and ecology

I will discuss this further in another article, as I don’t currently feel ready to do that. There are way too many problems and grey areas and I don’t think I know that much about it now.

As some of you might know I was writing an article for a competition that evaluates students’ semi-scientific works. My topic was environment and I was writing about fast fashion.

This is however a bit different. I wanted to make a structured list with the most important issues of ecological crisis in 21th century. So here are the 5 most threatening ecology issues and what you can do with it.

1. Air Pollution

According to the World Economic Forum, air pollution is considered to be a biggest threat to our health.

It is proven that up to 52 000 people in USA die from exposure to emissions from power plants. This number is even higher in other countries. In the world, there are 4.2 million premature deaths (yearly) as a result of an exposure to outdoor pollution.

Outdoor pollution can be a reason for diseases such as lung cancer, acute lower respiratory infections, strokes and other.

Can natural fog and mist be replaced with smog? There’s a possibility.

The pollutants are not unfamiliar to us. The most dangerous include PM (particulate matter), O3 (ozone), NO2 (nitrogen dioxide) and SO2 (sulphur dioxide).

However, nobody is really safe. 3.8 million people die each year because of household exposure to smoke from dirty cookstovesand fuels.

Additionally, over 91% of the world’s population lives where air quality exceeds the guideline limits provided by WHO (World’s Health Organization).

Air pollution is very serious issue and is considered the most dangerous one. Unfiltered toxic fumes from factories are one of the biggest environmental threats.

2. Plastic: Good Servant But A Bad Master

Plastic was considered a miracle when it was founded by scientists. People were so happy about this material they started to use it everywhere they could. It has many convenient characteristics that allow us to use it in everyday life.

However, the situation has changed. The once beloved plastic is currently floating around in oceans, polluting the beaches in Bali, suffocating the sea animals and changing the ocean’s climate, thus worrying 3.5 billion people who depend on  the ocean as their food source.

I’ve once read the scary statistics that in one of every 4 lobsters there is an exceeded amount of plastic microfibres presumably from clothing. These microfibres can easily modify and accumulate in our bodies, or animal corpses.

Sea turtles can become extinct if we continue.

3. Rising Seas As Threatening Ecology Issue

Seas are rising due to climate change and global warming. According to the newest evidence, the Earth got hotter by 0.9°C which sounds like it’s not a lot. However, our planet thinks otherwise.

The icebergs are melting, which causes that polar bears are becoming cannibals. They are eating their mates in order to survive. They are more skinnier due to the lack of nutrients and many of them are weaker and dying.

Polar bears possible extinction is not the only thing we need to worry about. It’s also the flooding. Amsterdam, Venice and other popular tourist destinations can be underwater in following years.
It is said that if we cut our emissions, we can reduce the sea level rising by almost a third. That is obviously great news. But are we capable to globally agree and do the actions necessary?

4. Decrease In Food Production

Everyone knows that feeding a growing world’s population is a significant challenge. However with global warming and climate change at our doors it will be even harder.

A 2014 research suggests that we may have problem in crop production especially in wheat, rice and maize. The yield losses will happen more often than in the first half of the century and the adaptation of the plants is not that great either.

5. Climate Refugees

With taking into consideration humanitarian crisis hitting Europe in 2016 and the incredible amount of refugees coming, climate refugees will be even greater challenge.

It is estimated that roughly 2 billion people may lose their home by 2100. That’s one-fifth of the world’s whole population. Their home countries will be intolerable for human life, flooded or unable to grow corps.

With the population growing, what is the solution to this?

I don’t know. But I know that buying more time helps with deciding what to do.

Do Your Part 

Maybe you’re not a politician or person in power, but you are still able to do things that can help.

1. Drive Less, Use Public Transportation

This is not always as easy as it seems. There isn’t public transport everywhere, sometimes it’s way too slow or just incredibly inconvenient.

If you’re travelling with your friends, go in one car rather than take multiple ones. Your carbon footprint will be reduced at least a bit and you’ll have a good time together.

Try not to buy as much plastic as you can. 

2. Try Not To Buy Groceries In Plastic

Maybe you won’t save the world, but you at least don’t contribute to the landfills with your rubbish. Plastic can be found everywhere and it’s incredibly hard to decompose.
After all, when it decompose in the landfills it emits methane which is, as we all know, a toxic gas.

Straws will be prohibited in EU, but there are still problem in USA and Australia, countries where people consume the most. Even if you’re not from one of these countries, beware of plastic straws and rather say no to them.

3. Reduce Food Waste

We actually throw away 40% of food we buy. This statistics is so sad as there are many people in the world that live in poverty and would give everything for the  groceries we put in a bin.

Actually, with the global food waste that is produced every year we can feed almost 1 billion those in poverty.

What about the expiration dates? There are also misconceptions about the date of expire. For example, best if used beforemeans that the item is at its peak of freshness. It doesn’t specify when it’s unsafe to consume the product.

Use-by indicates when the item starts deterioting in quality and flavour. It’s not a safety guide, but according to USDA it’s the best date to follow.

These are some of the most important tips in order to be a bit more eco-friendly. There are many other points I haven’t made in this article. It is because some of them are very popular and wide-known (don’t waste water while showering, don’t have artificial lights on for very long, use LED diods etc.


Of course, there are many environmental issues I haven’t mentioned as well, but I chose those that are both very threatening and quite often forgotten (with exception to air pollution).

If you want to do more, create pressure on your local politicians and media to cover more on ecology.

Our Earth is worth fighting for.
