Sam Chaginy SP3A Geography

1st What according to you is a healthy environment?

A healthy environment is an atmosphere we can enjoy to live without it affecting human and animal health negatively, such as reduced life span, diseases and irritations in our bodies, no nature dwell but only cities with mass emissions every day without stopping, which I believe can lead to the end of the human species itself.

2nd What is the big threat for the environment in the different partner countries? Is there a solution? What can industry do? What can you do as an individual?

That they think more about their country's economy and prosperity instead of contributing to the health and the environment in globally. But they did not think of is that the prosperity and future lies precisely in the environment, it is the environment that determines, not the economy or the country's status, we must consider that we want to use our remaining natural resources in the best way before the situation becomes too critical, we must think long-term and long-term action in practice. We negatively affect the earth which will result that in the end she will fight back with much greater consequences.

Industry can make rules and decisions for a healthy environment that will contribute to good a environmental future. For example, establish some days you cannot make use of factories and power plants, and land and air traffic, such as man can take distance from and show some respect, but that it should be no type of disaster as a result.

As an individual I can show my regard and respect for the environment by regularly walking and cycling or by taking the bus or the train which proved to be most energy efficient transport compared to cars, ships, jets and propeller planes, and that don’t use fossil fuels that contribute to global warming due to emissions of carbon dioxide.

I can also wash my clothes ecologically and eat ecological food, and can hope that growers around the world switch to ecological farming. Even though it may be more expensive than usual, you can buy ecological products now and then instead of buying too much of the usual and let the food stand and mold. We can think about what we consume, so that before we buy anything you can divide your food in primary and secondary needs and ask yourself if I really need this? Ecological food is better for the environment even if it has been transported somewhat longer than a local formally farmed product. And it takes lots of fossil energy to produce chemical pesticides and fertilizers. In addition, it doesn’t ruin the land and we avoid getting the chemicals in us when we eat ecological food. Lots of food is being thrown in the world and it's bad for the environment but if you buy ecological food you will be more careful of your food and will probably not throw as much as before and can help reduce the problem.

I can also think of smaller routines like: using the bicycle more often, turning the lights off everytime I leave my house and only using the lights in my room i'm present in and the other rooms' lights shut off and throwing junk in the garbage, and electric stuff such as batteries in a seperate place and use batteries that are rechargeable so you don't need to throw them away, take fast showers lesser than 10 min since a short shower is better than a long bath, return your bottles of beer and wine and get money and support the enviorment, a microwaver use less energy than a fireplace to warm your food and it's faster, use cold water from the watertap and shut it off when you don't use it and dont let it flow water when you don't use it, if you wanna order something from a store make sure the transport is environmentally friendly, when your going to eat something at a restaurant make sure you order vegetarian food since it takes lesser energy to produce vegetarian products than meat products, and if you ever find your clothes smelling smoke or something dirty you can always air your clothes instead of washing them since they are just smelling dirty not looking dirty, I can keep on going and mention a thousand of things that are daily routines but these are just a few to keep you openminded.

Nuclear power is one of the greatest threats to the environment if we do not stop it in time, what one produces in a nuclear factory and what becomes waste has a major impact on the environment and we can take the Chernobyl accident as an example, if this would happen to it repeats itself it would destroy both nature and people, emissions at all reduces human life and damage the health of heart and pave the way for lung diseases. In China, there are cities where people’s life is reduced by 10 years because of the bad air that people live in.

The same applies to population growth, unless there is a balance between birth and death with a constant population growth it will affect the environment very much because people in particular are those affecting the environment the most and can lead to poverty and poverty is of course an important factor you want to stop. A study by the UN shows that world’s population will double in about 30 years. 90% of this increase will occur in poor countries. The UN has also discovered that birth numbers slowly declining, the year 2025 we will reach a constant level. UN will also struggle to halve world poverty until 2050. http://www.transten.nu/filarkiv/malinsjobom.PDF

3rd What will the environment in Europe look like in 2050?

Either it will have improved, but perhaps not as much as you think through all the countries have cooperated to a healthier environmental future or will the Unions and the major powers not have reached a decision about making some change and then maybe someday we will pay for it in 2050. But otherwise, I believe at all that the lack of natural resources will have been greater than before so the world will, after all, do not look as good though maybe, we can start using what we have access to in the best possible way.

All the oil will have run out and we need to support us on renewable fuels, and the ice will be melting, animal species will be endangered, which will lead to perhaps take one of each species in captivity, the water level will have risen enough so countries will need water barriers. I think solar will be the main energy source to use in future as the sun is always there for us and maybe one of the few energies we can rely on long-term.

The greenhouse effect

“Greenhouse effect or the phenomenon called greenhouse effect that long-wave radiation are prevented from leaving a planet's atmosphere because of the so-called greenhouse gases, which in Earth's case helps keep the planet's temperature at a livable levelhttp://sv.wikipedia.org/wiki/Växthuseffekten

What’s important to know is when the earth's temperature increases it will support the coming of more and more hurricanes, storms and flooding and more tropical diseases and epidemics. There is also a lack of clean water in many parts of the world and it will be hard to come by when water sources dry up. There are also theories that the greenhouse effect will not be the main reason for the earth’s change. There are theories about a new ice age coming.

Ice age

Why occurs an ice age?

The reason that an ice age occurs, is variations in the strength of the sunlight that hits the earth (something that is in shorter cold periods has been associated with the number of sunspots on the sun).

How are glaciers built up?

“One would think that it is a cold winter that causes the glaciers are built up, but it is rather that the summers get shorter and shorter and the snow that falls during the winter so do not have time to melt away completely before the next winter occurs.http://sv.wikipedia.org/wiki/Istid

But it’s time to ask ourselves and think of what we can do, t

he earth and climate have survived for more than 6 billion years and will probably continue to do so, but the main question is whether we will survive?

Here is a video taken from youtube that explain theories whether it's going to be a global warming or a global cooling:
