In the first line, you capitalize 'love' unnecessarily.
When I see this, I see many sentences crushed together.
Agreed!! Holy moly, that is a lot of sentences crushed together.
Every paragraph should have one main idea.
I love to read, cook, walk through nature, and ride my bicycle. I'm a caretaker of nature, and I can`t stand pollution or things which are against the nature. --- this is one paragraph. Add sentences that are about nature.
Start a new paragraph:
I love to meet people around the world, I'm member of a community world called CouchSurging.org where our objective is show, guide and ....experience in our room.--- this is a good paragrpah, because it is all about one subject: culture.
Okay... here is the important point. When you write the essay, establish a theme at the start: salsa dancing. When you talk about these other things, talk about them by showing what they have in common with salsa dancing. Make it so that your whole life is like dancing in a way. This is how to keep a theme throughout the essay.
Know what I mean? The trick is to make the essay clever by showing how you can discuss all these things in terms of salsa. As it is right now, it seems like a list of facts instead of an essay, but you can use salsa as a "unifying theme."
