How to stay safe on a forest trip

My friend is planning a wildlife trip, to one of the deadly forests in the world. I was worried regarding safety of my friend , can someone show tips on protecting oneself from wild animals. Please give some insight into this...

which one of the "Deadly forests" are you talking about?

I suggest you buy a black market assault rifle and a professional hunting rifle. That way if the animal charges, you can try and kill it before it tears you apart. If you prefer handguns, make it a 45 caliber, a Magnum, or a Desert Eagle. The Desert Eagle is a rifle in the form of a hand gun, more like a cannon, but it makes nice holes in any animal you can actually hit with the heavy weapon, given its tendency to kick. Warning, It takes a while for a bear to realise it's dead, so killing it may be the last thing you do.

Best thing for bears is to raise your hands, and scream, unless it has a cub nearby. Then nothing nonviolent will save you. There is bear mace, but don't use human mace. That only makes the bear angrier.

A sword or spear might be useful if a tiger charges. Oh wait, Tigers only attack when your head is turned away from it, so wear one of those funny face masks on the back of your head all the time, even if there are no tigers. It may fool the odd cougar too.

Aside from that, the best solution is to stay out of their way. If a bear likes to attack your backpack, let it have it. Don't keep food in your car or tent. Keep it tied up in a tree in a bear proof container. Cars are not especially bear-proof if the bear is motivated.

Piranhas only attack people in the water, so just don't go into pirahna infested waters.

Make plenty of noise tramping around. Snakes appreciate the warning so they can get out of your way.

If a colony of army ants starts swarming near you, run away and pray you don't trip. You may go past the ants territory. Anything living on the ground or on trees eventually gets eaten, regardless of size.

everything contains some degree adventure factor, so my advice is, before planning to somewhere, first know it more, and that would be helpful for your adventure travel ~

I've seen pictures of polar bears being driven away by spray so that will work well in most cases, but the problem is when you are sleeping, what is going to stop the critter from reaching throuhg the tent and munchiing your friends head off. That is the worry. think about it enough and you won't sleep and that will solve the problem, you just stay up all night, crazed with fear, and having the time of your life.

We met a guy in Estonia - he had a long white beard and believed he was Santa Claus's helper (in fact he went to school with Santa) - anyway, he could make himself invisible and that kept him safe from both animals and police in forests.

Truly.

Well, that's what he said.
