So basically, I will be applying to university in about 6 months, but I've been struggling to narrow down my options for a major. Being a person whose obsessed with Wildlife in general, I've thought of environmental science, zoology, agriculture, marine biology... my main dilemma is not knowing which of these (or anything similar) will be easiest to find a job with in Europe (I live in Denmark but don't necessarily plan on staying).would really appreciate help of any sort

My advice would be to go online and looking for the salary around your area (or where you are looking to go). This would allow you to see all of options that you have. In the end it's all up to you so the best of luck in your endeavors.

I will disagree, if salary alone is the issue, be a doctor.

But you need to consider what type of job you want, and follow a path to that.

If not, just do general studies for the first year to two,

Where in the world is there a university that requires that a first year student chose a major? It is totally unnecessary to even worry about classes yet, much less a major. Virtually every science and math and computer course, and even languages and history, will provide the broad base you need for ANY specialized career.

Being obsessed with wildlife means a career, no matter how you slice it. Some don't pay well, but there will be jobs all over the world. And if you go back for a PhD later, you will then really know what your obsession boils down to. And the wildlife of the earth is changing daily, so your value may change as each year goes by.

Many careers overlap. Yesterday's chemist might solve today's bee dying mystery. A computer programmer might be needed for a marine study. Geologists contribute to the knowledge of species extinction. The list goes on!

Make a list of the fields you are interested in, and find the courses requirements you need to qualify for each one. This will give you an idea of what you should be focusing on as far as the basic for the first few years while you decide your major. Your major can change, likely will, and there is also a minor study to consider, so you keep your options in front of you until you finally decide. This also give you an idea of which university best fits you, and that leads to a good guidance counselor to point you in the right direction.

Comes down to preparation and research before you make a decision. It's a process.

The problem is not knowing where you want to end up. For me, as long as the work is outside and interactive with nature and the animals, I'll be more than satisfied.

I'd visit my academic advisor during my first year of study. You should be taking general courses, and you can be an "undeclared" major for that year. Don't rush your decision. You have plenty of time to decide.
